Subject: Input: add matrix keypad driver for Cirrus EP93xx

This is a keyboard driver for the Cirrus Logic EP93xx keypad matrix
peripheral. This driver is based on the pxa27x_keypad driver.

[dtor@mail.ru: Plug in input_dev->keycode so keymap can be changed
		from userspace.]

Subject: Intel IOMMU Pass Through Support

The patch adds kernel parameter intel_iommu=pt to set up pass through
mode in context mapping entry. This disables DMAR in linux kernel; but
KVM still runs on VT-d and interrupt remapping still works.

In this mode, kernel uses swiotlb for DMA API functions but other VT-d
functionalities are enabled for KVM. KVM always uses multi level
translation page table in VT-d. By default, pass though mode is disabled
in kernel.

This is useful when people don't want to enable VT-d DMAR in kernel but
still want to use KVM and interrupt remapping for reasons like DMAR
performance concern or debug purpose.

Subject: ACPI: Disable ARB_DISABLE on platforms where it is not needed

ARB_DISABLE is a NOP on all of the recent Intel platforms.

For such platforms, reduce contention on c3_lock
by skipping the fake ARB_DISABLE.

Subject: mtd: nand: davinci_nand, 4-bit ECC for smallpage

Minimal support for the 4-bit ECC engine found on DM355, DM365,
DA830/OMAP-L137, and similar recent DaVinci-family chips.

This is limited to small-page flash for now; there are some page
layout issues for large page chips.  Note that most boards using
this engine (like the DM355 EVM) include 2GiB large page chips.

Sanity tested on DM355 EVM after swapping the socketed NAND for
a small-page one.

Subject: CRIS: assignment/is equal confusion

Somehow, the assignments of rw->lock got written as comparisons.
The effect probably was that the read-write spinlocks never locked.
However, since the locks are only used in CONFIG_SMP and SMP CRIS is
experimental, it has never been identified as a problem.

Subject: CRISv32: Fix potential null reference in cryptocop driver.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The code didn't test the pointer to the newly allocated
memory, but a parameter sent in as value.
Since the input parameter was most often set, the code
would have used a null pointer if the kmalloc failed.
If the input parameter was not set, the code would
leak the allocated buffer.

define TIMER_VECT1 is always unset, and the error was never triggered.

Move the brace down below the #endif.

Subject: sh: Fix dynamic ftrace's NOP action.

Ftrace on sh handles nop'ing out trace function calls differently than
other architectures. Instead of inserting NOP instructions in place of
the call to the function tracer we branch over the call instructions
and continue executing the main body of the function.

This patch fixes a bug in the implementation of ftrace_modify_code()
where we check that the old value of the code we're about to replace
is an expected one. In the ftrace_make_call() code path
ftrace_modify_code() was comparing the old instruction value with NOP
instructions. The compare was failing because we never actually insert
NOP instructions. It makes sense to just get rid of the NOP
instructions in ftrace_nop and compare the old code with the address
of the function body if we're expecting ftrace to have nop'd out the
function trace call.

Subject: PCI/x86: don't assume prefetchable ranges are 64bit

We should not assign 64bit ranges to PCI devices that only take 32bit
prefetchable addresses.

Try to set IORESOURCE_MEM_64 in 64bit resource of pci_device/pci_bridge
and make the bus resource only have that bit set when all devices under
it support 64bit prefetchable memory.  Use that flag to allocate
resources from that range.

Subject: PCI: use ACPI _CRS data by default

At this point, it seems to solve more problems than it causes, so let's try using it by default.  It's an easy revert if it ends up causing trouble.

Subject: ACPI, PCI, x86: move MCFG parsing routine from ACPI to PCI file

Move
arch/x86/kernel/acpi/boot.c: acpi_parse_mcfg()
to
arch/x86/pci/mmconfig-shared.c: pci_parse_mcfg()
where it is used, and make it static.

Move associated globals and helper routine with it.

No functional change.

This code move is in preparation for SFI support,
which will allow the PCI code to find the MCFG table
on systems which do not support ACPI.

Subject: cpumask: arch_send_call_function_ipi_mask: sh

We're weaning the core code off handing cpumask's around on-stack.
This introduces arch_send_call_function_ipi_mask(), and by defining
it, the old arch_send_call_function_ipi is defined by the core code.

Subject: cpumask: use mm_cpumask() wrapper: sh

Makes code futureproof against the impending change to mm->cpu_vm_mask.

It's also a chance to use the new cpumask_ ops which take a pointer
(the older ones are deprecated, but there's no hurry for arch code).

Subject: sh: Bump the earlytimer bits back to time_init().

These were handled through late_time_init due to kmalloc() and friends
not being available earlier on previously. Now with slab caches being
available much earlier, this is no longer necessary, and we can move the
initialization up to an earlier point. One of the benefits with this is
that printk times are available a bit earlier!

Date: Sun, 14 Jun 2009 20:02:30 +0900
Subject: sh: Bump the earlytimer probe devices up.

Presently the earlytimer probe handles the clockevents driver, which
requires that the clockevents driver be registered first. This bumps it
up by 1 to include the clocksource device, which can be safely ignored
if it doesn't exist, as we will simply error out on that path and defer
to the jiffies clocksource.

Subject: sh: Make the atomic functions safe for irqsoff tracing

The irqsoff tracer uses the atomic_* functions internally, but the
implementations of those functions in arch/sh/include/asm/atomic-irq.h
disable irqs to achieve atomicity. A continuous loop ensues where we
disable interrupts, trace the interrupt disabling, call atomic_*
functions, disable interrupts, trace the interrupt disabling, etc..

The simplest solution to all this is to just convert uses of
local_irq_save()/local_irq_restore() the raw_* equivalents because the
raw_* equivalents don't call trace_hardirqs_on()/trace_hardirqs_off().

Subject: x86: hpet: Mark per cpu interrupts IRQF_TIMER to prevent resume
 failure

timer interrupts are excluded from being disabled during suspend. The
clock events code manages the disabling of clock events on its own
because the timer interrupt needs to be functional before the resume
code reenables the device interrupts.

The hpet per cpu timers request their interrupt without setting the
IRQF_TIMER flag so suspend_device_irqs() disables them as well which
results in a fatal resume failure on the boot CPU.

Adding IRQF_TIMER to the interupt flags when requesting the hpet per
cpu timer interrupts solves the problem.

Subject: perf_counter, x86: Fix kernel-space call-chains

Kernel-space call-chains were trimmed at the first entry because
we never processed anything beyond the first stack context.

Allow the backtrace to jump from NMI to IRQ stack then to task stack
and finally user-space stack.

Also calculate the stack and bp variables correctly so that the
stack walker does not exit early.

We can get deep traces as a result, visible in perf report -D output:

0x32af0 [0xe0]: PERF_EVENT (IP, 5): 15134: 0xffffffff815225fd period: 1
... chain: u:2, k:22, nr:24
.....  0: 0xffffffff815225fd
.....  1: 0xffffffff810ac51c
.....  2: 0xffffffff81018e29
.....  3: 0xffffffff81523939
.....  4: 0xffffffff81524b8f

.....  9: 0xffffffff810d9b74
..... 10: 0xffffffff810dbeec
..... 11: 0xffffffff810dc3fb

This is a 22-entries kernel-space chain.

(We still only record reliable stack entries.)

Subject: amd-iommu: flush domain tlb when attaching a new device

When kexec'ing to a new kernel (for example, when crashing and launching
a kdump session), the AMD IOMMU may have cached translations.  The kexec'd
kernel, during initialization, will invalidate the IOMMU device table
entries, but not the domain translations.  These stale entries can cause
a device's DMA to fail, makes it rough to write a dump to disk when the
disk controller can't DMA ;-)

Subject: amd-iommu: disable cmd buffer and evt logging before reprogramming
 iommu

The IOMMU spec states that IOMMU behavior may be undefined when the
IOMMU registers are rewritten while command or event buffer is enabled.
Disable them in IOMMU disable path.

Subject: perf_counter: x86: Fix call-chain support to use NMI-safe methods

__copy_from_user_inatomic() isn't NMI safe in that it can trigger
the page fault handler which is another trap and its return path
invokes IRET which will also close the NMI context.

Therefore use a GUP based approach to copy the stack frames over.

We tried an alternative solution as well: we used a forward ported
version of Mathieu Desnoyers's "NMI safe INT3 and Page Fault" patch
that modifies the exception return path to use an open-coded IRET with
explicit stack unrolling and TF checking.

This didnt work as it interacted with faulting user-space instructions,
causing them not to restart properly, which corrupts user-space
registers.

Solving that would probably involve disassembling those instructions
and backtracing the RIP. But even without that, the code was deemed
rather complex to the already non-trivial x86 entry assembly code,
so instead we went for this GUP based method that does a
software-walk of the pagetables.

Subject: perf_counter: Make set_perf_counter_pending() declaration common

At present, every architecture that supports perf_counters has to
declare set_perf_counter_pending() in its arch-specific headers.
This consolidates the declarations into a single declaration in one
common place, include/linux/perf_counter.h.  On powerpc, we continue
to provide a static inline definition of set_perf_counter_pending()
in the powerpc hw_irq.h.

Also, this removes from the x86 perf_counter.h the unused null
definitions of {test,clear}_perf_counter_pending.

Subject: x86: Add NMI types for kmap_atomic, fix

I just realized this has a kmap_atomic bug in...

The below would fix it - but it's complicating this code
some more.

Alternatively I would have to introduce something like
pte_offset_map_irq() which would make the irq/nmi detection and leave
the regular code paths alone, however that would mean either duplicating
the gup_fast() pagewalk or passing down a pte function pointer, which
would only duplicate the gup_pte_range() bit, neither is really
attractive ...

Subject: [CPUFREQ] Clean up convoluted code in
 arch/x86/kernel/tsc.c:time_cpufreq_notifier()

Christoph Hellwig noticed the following potential uninitialised use:

 > arch/x86/kernel/tsc.c: In function 'time_cpufreq_notifier':
 > arch/x86/kernel/tsc.c:634: warning: 'dummy' may be used uninitialized in this function
 >
 > where we do have CONFIG_SMP set, freq->flags & CPUFREQ_CONST_LOOPS is
 > true and ref_freq is false.

It seems plausable, though the circumstances for hitting it are really low.
Nearly all SMP capable cpufreq drivers set CPUFREQ_CONST_LOOPS.
powernow-k8 is really the only exception. The older CPUs were typically
only ever UP. (powernow-k7 never supported SMP for eg)

It's worth fixing regardless, as it cleans up the code.

Fix possible uninitialized use of dummy, by just removing it,
and making the setting of lpj more obvious.

By definition, "cpuinfo_cur_freq" should report the value from HW. So, don't
depend on the cached value. Instead read P-state directly from HW, while
taking into account the erratum 311 workaround for Fam 11h processors.

Subject: [CPUFREQ] cpumask: avoid playing with cpus_allowed in speedstep-ich.c

Impact: don't play with current's cpumask

It's generally a very bad idea to mug some process's cpumask: it could
legitimately and reasonably be changed by root, which could break us
(if done before our code) or them (if we restore the wrong value).

We use smp_call_function_single: this had the advantage of being more
efficient, too.

Subject: [CPUFREQ] cpumask: avoid cpumask games in
 arch/x86/kernel/cpu/cpufreq/speedstep-centrino.c

Impact: don't play with current's cpumask

It's generally a very bad idea to mug some process's cpumask: it could
legitimately and reasonably be changed by root, which could break us
(if done before our code) or them (if we restore the wrong value).

Use rdmsr_on_cpu and wrmsr_on_cpu instead.

cpumask: avoid playing with cpus_allowed in powernow-k8.c

It's generally a very bad idea to mug some process's cpumask: it could
legitimately and reasonably be changed by root, which could break us
(if done before our code) or them (if we restore the wrong value).

I did not replace powernowk8_target; it needs fixing, but it grabs a
mutex (so no smp_call_function_single here) but Mark points out it can
be called multiple times per second, so work_on_cpu is too heavy.

Subject: sh: smsc911x support for the rsk7203 board

This patch adds support for the LAN9118 ethernet on rsk7203.

The LAN9118 controller is hooked up using a 16-bit data bus,
but the rsk7203 board does not swap the byte lanes as needed
between the sh7203 processor and the the ethernet controller.

In the processor the CS memory window is configured in 16-bit
mode but the smsc911x driver is told to do 32-bit accesses to
improve performance. The SMSC911X_SWAP_FIFO flag is used
to tell the driver to do software byte swapping of fifo data.

Subject: sh: pci: Allow register_pci_controller() to handle overlapping
 regions.

Some host controllers (such as SH7786) have overlapping regions that are
fixed in hardware. The resource allocator does the right thing in
managing this space already, so the conflict case is non-fatal.

Subject: [ARM] MINI2440: Add machine support

The MINI2440 is a chinese made s3c2440 development board with
a large set of peripherals.
This patch provides machine support for almost all the features
of the board.

Since it can come with various "options" fitted, a kernel parameter
is used to specify the lcd size, backlight control and touchscreen.

Subject: [IA64] remove obsolete no_irq_type

The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
been kept around for migration reasons.  After more than two years it's
time to remove them finally.

This patch cleans up one of the remaining users.  When all such patches
hit mainline we can remove the defines and typedefs finally.

Impact: cleanup

convert the last remaining users to no_irq_chip

Convert the last remaining users to struct irq_chip and remove the
define.

Subject: powerpc: Add 86xx support for SWIOTLB

This is the final bit of code to allow enabling swiotlb on
mpc86xx.  The platform-specific code is very small and consists
of enabling SWIOTLB in the config file, registering the
swiotlb_setup_bus_notifier initcall, and setting pci_dma_ops
to point to swiotlb_pci_dma_ops if we have more memory than
can be mapped by the inbound PCI windows.

Subject: powerpc/85xx: Add SWIOTLB support to FSL boards

Add the platform-specific code for enabling SWIOTLB if needed on P2020DS,
MPC85xx DS, and MPC85xx MDS boards as they are capable of having >4G of
memory.

We determine if we need to enable swiotlb based on how much memory is in
the board and if it exceeds 4G or what we can map via PCI inbound
windows.

Subject: powerpc/mpc8272ads: fix device tree for 8 MB flash size

The current device tree for the MPC8272ADS assumes a mapping of 32 MB
of NOR flash at 0xFE00.0000, while there are actually only 8 MB on
the boards, mapped at 0xFF80.0000. When booting an uImage with such a
device tree, the kernel crashes because 0xFE00.0000 is not mapped.

Also introduce aliases for serial[01] and ethernet[01].

Subject: powerpc/83xx: Update sdhci nodes per new bindings

As of commit 404614728f857d0ac63d29c3a29d0cf392a15598 ("Update FSL
esdhc binding"), we use "fsl,esdhc" compatible entry as a base
match. U-Boot will use the same compatible to fixup esdhc nodes.

This patch updates 83xx dts files so that they conform to the new
bindings.

Subject: powerpc/mpc83xx: Fix usb mux setup for mpc834x

usb0 and usb1 mux settings in the sicrl register were swapped (twice!)
in mpc834x_usb_cfg(), leading to various strange issues with fsl-ehci
and full speed devices.

The USB port config on mpc834x is done using 2 muxes: Port 0 is always
used for MPH port 0, and port 1 can either be used for MPH port 1 or DR
(unless DR uses UTMI phy or OTG, then it uses both ports) - See 8349 RM
figure 1-4..

mpc8349_usb_cfg() had this inverted for the DR, and it also had the bit
positions of the usb0 / usb1 mux settings swapped. It would basically
work if you specified port1 instead of port0 for the MPH controller (and
happened to use ULPI phys), which is what all the 834x dts have done,
even though that configuration is physically invalid.

Instead fix mpc8349_usb_cfg() and adjust the dts files to match reality.

Subject: powerpc: Enable additional BAT registers in setup_745x_specifics()

Currently the kernel expects the additional four IBAT and DBAT registers
to be available, but doesn't enable these registers on 745x CPUs, which
have them disabled after reset. Thus set the HIGH_BAT_EN bit in HID0
register, if the corresponding MMU feature is defined.

Subject: powerpc/85xx: cuboot - Fix up ethernet3 MAC address on MPC85xx

Some MPC85xx platforms do support 4 ethernet ports, so make sure the boot
wrapper fixes up all of them in the fdt.

Since MAC addresses are at the end of the bd_t structure there is no harm
in expanding to support 4 MAC address on older 85xx systems that might not
have that many.

Currently the fsl,*lbc devices support 8 banks (ie OR and BR registers).
This is adequate for most pq2 and pq3 processors, but not the MPC8280 which

Subject: 83xx: add support for the kmeter1 board.

The following series implements basic board support for
the kmeter1 board from keymile, based on a MPC8360.

This series provides the following functionality:

- The board can boot with a serial console on UART1
- Ethernet:
    UCC1 in RGMII mode
    UCC2 in RGMII mode
    UCC4 in RMII mode
    UCC5 in RMII mode
    UCC6 in RMII mode
    UCC7 in RMII mode
    UCC8 in RMII mode

    following patch is necessary for working UCC in RMII mode:

    http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-April/070804.html

- Flash accessed via MTD layer

  On this hardware there is an Intel P30 flash, following patch
  series is necessary for working with this hardware:

  http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-April/070624.html

- I2C using I2C Bus 1 from the MPC8360 cpu

Subject: powerpc/bootwrapper: Custom build options for XPedite52xx targets

Some XPedite52xx boards have a legacy boot loader requiring some special
care in the boot wrapper.  The use of cuboot-85xx is needed to fix
up embedded device trees, and a custom link address is specified to
accommodate the boot loader and larger kernel image sizes used on X-ES
MPC85xx platforms.

Subject: powerpc/warp: Fix ISA_DMA_THRESHOLD default

If no device is passed to __dma_alloc_coherent, it defaults to using ISA_DMA_THRESHOLD
for the mask. This patch provides a reasonable default rather than 0.

Subject: powerpc: Introduce macro spin_event_timeout()

The macro spin_event_timeout() takes a condition and timeout value
(in microseconds) as parameters.  It spins until either the condition is true
or the timeout expires.  It returns the result of the condition when the loop
was terminated.

This primary purpose of this macro is to poll on a hardware register until a
status bit changes.  The timeout ensures that the loop still terminates if the
bit doesn't change as expected.  This macro makes it easier for driver
developers to perform this kind of operation properly.

Subject: powerpc: Add configurable -Werror for arch/powerpc

Add the option to build the code under arch/powerpc with -Werror.

The intention is to make it harder for people to inadvertantly introduce
warnings in the arch/powerpc code. It needs to be configurable so that
if a warning is introduced, people can easily work around it while it's
being fixed.

The option is a negative, ie. don't enable -Werror, so that it will be
turned on for allyes and allmodconfig builds.

The default is n, in the hope that developers will build with -Werror,
that will probably lead to some build breaks, I am prepared to be flamed.

It's not enabled for math-emu, which is a steaming pile of warnings.

Subject: powerpc: Fix invalid construct in our CPU selection Kconfig

commit 5b7c3c918c9c26c50d220b2b50359208cb5a1dbe introduced an invalid
construct in our CPU selection. This caused warnings, though it still
appeared to do the right thing.

This fixes it properly by having separate formal definitions of
PPC_BOOK3S_32 and PPC_BOOK3S_64 and one statement defining
PPC_BOOK3S based on the two above.

Subject: powerpc: Add memory clobber to mtspr()

Without this clobber, mtspr can be re-ordered by gcc vs. surrounding
memory accesses. While this might be ok for some cases, it's not in
others and I'm not confident that all callers get it right (In fact
I'm sure some of them don't).

So for now, let's make mtspr() itself contain a memory clobber until
we can audit and fix everything, at which point we can remove it
if we think it's worth doing so.

Subject: amd-iommu: resume cleanup

Now that enable_iommus() will call iommu_disable() for each iommu,
the call to disable_iommus() during resume is redundant.  Also, the order
for an invalidation is to invalidate device table entries first, then
domain translations.

Subject: x86: mm: Read cr2 before prefetching the mmap_lock

Prefetch instructions can generate spurious faults on certain
models of older CPUs. The faults themselves cannot be stopped
and they can occur pretty much anywhere - so the way we solve
them is that we detect certain patterns and ignore the fault.

There is one small path of code where we must not take faults
though: the #PF handler execution leading up to the reading
of the CR2 (the faulting address). If we take a fault there
then we destroy the CR2 value (with that of the prefetching
instruction's) and possibly mishandle user-space or
kernel-space pagefaults.

It turns out that in current upstream we do exactly that:

	prefetchw(&mm->mmap_sem);

	/* Get the faulting address: */
	address = read_cr2();

This is not good.

So turn around the order: first read the cr2 then prefetch
the lock address. Reading cr2 is plenty fast (2 cycles) so
delaying the prefetch by this amount shouldnt be a big issue
performance-wise.

[ And this might explain a mystery fault.c warning that sometimes
  occurs on one an old AMD/Semptron based test-system i have -
  which does have such prefetch problems. ]

Subject: [ARM] pxa/mioa701: add V3 gain configuration for Maxim 1586 voltage
 regulator

Maxim 1586 V3 gain can be configured by external resistors
(R24, R25) connected to the FB3 pin. To avoid accidental
overvoltage, it now requires this gain to be configured
explicitly.

Subject: [IA64] ia64 does not need umount2() syscall

ia64 doesn't have old and new versions of the umount system call.
It just has the new version.

Fixes this build warning:
<stdin>:395:2: warning: #warning syscall umount2 not implemented

Subject: PCI AER: support Multiple Error Received and no error source id

Based on PCI Express AER specs, a root port might receive multiple
TLP errors while it could only save a correctable error source id
and an uncorrectable error source id at the same time. In addition,
some root port hardware might be unable to provide a correct source
id, i.e., the source id, or the bus id part of the source id provided
by root port might be equal to 0.

The patchset implements the support in kernel by searching the device
tree under the root port.

Patch 1 changes parameter cb of function pci_walk_bus to return a value.
When cb return non-zero, pci_walk_bus stops more searching on the
device tree.

Subject: x86/ACPI: Correct maximum allowed _CRS returned resources and warn if
 exceeded

Issue a warning if _CRS returns too many resource descriptors to be
accommodated by the fixed size resource array instances.  If there is no
transparent bridge on the root bus "too many" is the
PCI_BUS_NUM_RESOURCES size of the resource array.  Otherwise, the last 3
slots of the resource array must be excluded making the maximum
(PCI_BUS_NUM_RESOURCES - 3).

The current code:
 - is silent when _CRS returns too many resource descriptors and
 - incorrectly allows use of the last 3 slots of the resource array
   for a root bus with a transparent bridge

Subject: [ARM] S3C64XX: Initial support for DVFS

This patch provides initial support for CPU frequency scaling on the
Samsung S3C ARM processors. Currently only S3C6410 processors are
supported, though addition of another data table with supported clock
rates should be sufficient to enable support for further CPUs.

Use the regulator framework to provide optional support for DVFS in
the S3C cpufreq driver. When a software controllable regulator is
configured the driver will use it to lower the supply voltage when
running at a lower frequency, giving improved power savings.

When regulator support is disabled or no regulator can be obtained
for VDDARM the driver will fall back to scaling only the frequency.

Subject: [ARM] GTA02/FreeRunner: Add machine definition

This patch introduces the Openmoko GTA02 machine definition.

Much of the code is based on Harald Welte's work, although it
has been largely rewritten several times.

This is intended to be the minimum machine definition to boot and
be able to run a rootfs from NAND on GTA02 / FreeRunner.  It does
not bring up the framebuffer / Glamo and lacks many other peripheral
drivers from outside the SoC.  But once we have this basis in
mainline kernel, we will be able to introduce the other drivers
and add them here.

Thanks to Sven Rebhan <odinshorse@googlemail.com> for his fixes to this
patch (Kconfig and defconfig files).

Subject: x86, mce: fix a race condition about mce_callin and no_way_out

If one CPU has no_way_out == 1, all other CPUs should have no_way_out
== 1. But despite global_nwo is read after mce_callin, global_nwo is
updated after mce_callin too. So it is possible that some CPU read
global_nwo before some other CPU update global_nwo, so that no_way_out
== 1 for some CPU, while no_way_out == 0 for some other CPU.

This patch fixes this race condition via moving mce_callin updating
after global_nwo updating, with a smp_wmb in between. A smp_rmb is
added between their reading too.

In mce_cpu_restart, mce_init_timer is called unconditionally.
If !mce_available (e.g. mce is disabled), there are no useful work
for timer.  Stop running it.

Subject: x86, mce: rename static variables around trigger

"trigger" is not straight forward name for valiable that holds name
of user mode helper program which triggered by machine check events.

This patch renames this valiable and kins to more recognizable names.

	trigger		=> mce_helper
	trigger_argv	=> mce_helper_argv
	notify_user	=> mce_need_notify

No functional changes.

From 9e55e44e39798541ba39d57f4b569deb555ae1ce Mon Sep 17 00:00:00 2001
From: Hidetoshi Seto <seto.hidetoshi@jp.fujitsu.com>
Date: Mon, 15 Jun 2009 17:22:15 +0900
Subject: x86, mce: unify mce.h

There are 2 headers:
	arch/x86/include/asm/mce.h
	arch/x86/kernel/cpu/mcheck/mce.h
and in the latter small header:
	#include <asm/mce.h>

This patch move all contents in the latter header into the former,
and fix all files using the latter to include the former instead.

Subject: x86, mce: make mce_disabled boolean

The mce_disabled on 32bit is a tristate variable [1,0,-1],
while 64bit version is boolean [0,1].
This patch makes mce_disabled always boolean, and use mce_p5_enabled
to indicate the third state instead.

Subject: x86: cap iomem_resource to addressable physical memory

iomem_resource is by default initialized to -1, which means 64 bits of
physical address space if 64-bit resources are enabled.  However, x86
CPUs cannot address 64 bits of physical address space.  Thus, we want
to cap the physical address space to what the union of all CPU can
actually address.

Without this patch, we may end up assigning inaccessible values to
uninitialized 64-bit PCI memory resources.

Subject: x86: correct the conversion of EFI memory types

This patch causes all the EFI_RESERVED_TYPE memory reservations to be recorded
in the e820 table as type E820_RESERVED.

(This patch replaces one called 'x86: vendor reserved memory type'.
 This version has been discussed a bit with Peter and Yinghai but not given
 a final opinion.)

Without this patch EFI_RESERVED_TYPE memory reservations may be
marked usable in the e820 table. There may be a collision between
kernel use and some reserver's use of this memory.

(An example use of this functionality is the UV system, which
 will access extremely large areas of memory with a memory engine
 that allows a user to address beyond the processor's range.  Such
 areas are reserved in the EFI table by the BIOS.
 Some loaders have a restricted number of entries possible in the e820 table,
 hence the need to record the reservations in the unrestricted EFI table.)

The call to do_add_efi_memmap() is only made if "add_efi_memmap" is specified
on the kernel command line.

So far, MPC512x used mpc512x_find_ips_freq() to get the bus frequency,
while MPC52xx used mpc52xx_find_ipb_freq().  Despite the different
clock names (IPS vs. IPB) the code was identical.

Use common code for both processor families.

Subject: powerpc/5121: make clock debug output more readable

This patch refactors clock.c by replacing printk calls with
pr_info/pr_cont, and uses '=' in output to connect key/value pairs

Subject: sh: Generic HAVE_PERF_COUNTER support.

This enables support for the generic software-based perf counters.

Hardware counter support could be added in the future, but the lack
of a performance counter IRQ makes this rather dubious.

Subject: sh: pci: Initial PCI-Express support for SH7786 Urquell board.

This adds initial support for the PCI-Express module in the SH7786,
particularly as it relates to the urquell platform. Presently it is
only supported in root complex mode, with endpoint mode still requiring
more debugging. 29/32-bit mode and lane configurations are selectable via
board mode pins, and are otherwise fixed.

Only 4x and 1x PCI channels are presently handled, the PCI bridge still
requires additional debugging and stabilization in hardware.

Subject: MIPS: TXx9: micro optimization for clocksource and clock_event

Use container structure for clocksource, clock_event_device and hold a
pointer to txx9_tmr_reg in it.

This saves a few instructions in clocksource and clock_event handlers.

+ * while the channel should occupy the FIFO buffer for effective

+ * Instead of dynamically assign the FIFO buffer to channels, I chose

From e6f72d3abafd50984decc2833c706e717f5ba04e Mon Sep 17 00:00:00 2001

Subject: MIPS: Replace some magic numbers with symbolic values in tlbex.c

The logic used to split the r4000 refill handler is liberally
sprinkled with magic numbers.  We attempt to explain what they are and
normalize them against a new symbolic value (MIPS64_REFILL_INSNS).

Subject: MIPS: Fold the TLB refill at the vmalloc path if possible.

Try to fold the 64-bit TLB refill handler opportunistically at the
beginning of the vmalloc path so as to avoid splitting execution flow in
half and wasting cycles for a branch required at that point then.  Resort
to doing the split if either of the newly created parts would not fit into
its designated slot.

Subject: MIPS: Allow R2 CPUs to turn off generation of 'ehb' instructions.

Some CPUs do not need ehb instructions after writing CP0 registers.
By allowing ehb generation to be overridden in
cpu-feature-overrides.h, we can save a few instructions in the TLB
handler hot paths.

Subject: MIPS: ioctl.h: Cleanup.

 o Rewrite to use <asm-generic/ioctl.h>.  Cuts down the file from 40 to
   16 lines.
 o Delete _IOC_VOID, _IOC_OUT, _IOC_IN and _IOC_INOUT.  They were added
   for 2.1.14 but I was not able to find any user - not even historical
   ones.

From 51e02b02e650183ff1277bcbad6a01d6ea0e9edb Mon Sep 17 00:00:00 2001
From: Manuel Lauss <manuel.lauss@googlemail.com>

Subject: MIPS: Alchemy: Rewrite GPIO support.

The current in-kernel Alchemy GPIO support is far too inflexible for
all my use cases.  To address this, the following changes are made:

* create generic functions which deal with manipulating the on-chip
  GPIO1/2 blocks.  Such functions are universally useful.
* Macros for GPIO2 shared interrupt management and block control.
* support for both built-in CONFIG_GPIOLIB and fast, inlined GPIO macros.

  If CONFIG_GPIOLIB is not enabled, provide linux gpio framework
  compatibility by directly inlining the GPIO1/2 functions.  GPIO access
  is limited to on-chip ones and they can be accessed as documented in
  the datasheets (GPIO0-31 and 200-215).

  If CONFIG_GPIOLIB is selected, two (2) gpio_chip-s, one for GPIO1 and
  one for GPIO2, are registered.  GPIOs can still be accessed by using
  the numberspace established in the databooks.

  However this is not yet flexible enough for my uses:  My Alchemy
  systems have a documented "external" gpio interface (fixed, different
  numberspace) and can support a variety of baseboards, some of which
  are equipped with I2C gpio expanders.  I want to be able to provide
  the default 16 GPIOs of the CPU board numbered as 0..15 and also
  support gpio expanders, if present, starting as gpio16.

  To achieve this, a new Kconfig symbol for Alchemy is introduced,
  CONFIG_ALCHEMY_GPIO_INDIRECT, which boards can enable to signal
  that they don't want the Alchemy numberspace exposed to the outside
  world, but instead want to provide their own.  Boards are now respon-
  sible for providing the linux gpio interface glue code (either in a
  custom gpio.h header (in board include directory) or with gpio_chips).

  To make the board-specific inlined gpio functions work, the MIPS
  Makefile must be changed so that the mach-au1x00/gpio.h header is
  included _after_ the board headers, by moving the inclusion of
  the mach-au1x00/ to the end of the header list.

  See arch/mips/include/asm/mach-au1x00/gpio.h for more info.

Subject: MIPS: TLB support for hugetlbfs.

The TLB handlers need to check for huge pages and give them special
handling.  Huge pages consist of two contiguous sub-pages of physical
memory.

* Loading entrylo0 and entrylo1 need to be handled specially.

* The page mask must be set for huge pages and then restored after
  writing the TLB entries.

* The PTE for huge pages resides in the PMD, we halt traversal of the
  tables there.

[Ralf: SMP support requires CPU hotplugging which MIPS currently doesn't
support.  As implemented in this patch cache and tlb flushing will also be
invoked with interrupts disabled so smp_call_function() will blow up in
charming ways.  So limit to !SMP.]

Subject: sched, x86: Fix cpufreq + sched_clock() TSC scaling

For freqency dependent TSCs we only scale the cycles, we do not account
for the discrepancy in absolute value.

Our current formula is: time = cycles * mult

(where mult is a function of the cpu-speed on variable tsc machines)

Suppose our current cycle count is 10, and we have a multiplier of 5,
then our time value would end up being 50.

Now cpufreq comes along and changes the multiplier to say 3 or 7,
which would result in our time being resp. 30 or 70.

That means that we can observe random jumps in the time value due to
frequency changes in both fwd and bwd direction.

So what this patch does is change the formula to:

  time = cycles * frequency + offset

And we calculate offset so that time_before == time_after, thereby
ridding us of these jumps in time.

[ Impact: fix/reduce sched_clock() jumps across frequency changing events ]

Subject: x86, io_apic.c: Work around compiler warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This compiler warning:

  arch/x86/kernel/apic/io_apic.c: In function ‘ioapic_write_entry’:
  arch/x86/kernel/apic/io_apic.c:466: warning: ‘eu’ is used uninitialized in this function
  arch/x86/kernel/apic/io_apic.c:465: note: ‘eu’ was declared here

Is bogus as 'eu' is always initialized. But annotate it away by
initializing the variable, to make it easier for people to notice
real warnings. A compiler that sees through this logic will
optimize away the initialization.

Subject: [IA64] Convert ia64 to use int-ll64.h

It is generally agreed that it would be beneficial for u64 to be an
unsigned long long on all architectures.  ia64 (in common with several
other 64-bit architectures) currently uses unsigned long.  Migrating
piecemeal is too painful; this giant patch fixes all compilation warnings
and errors that come as a result of switching to use int-ll64.h.

Note that userspace will still see __u64 defined as unsigned long.  This
is important as it affects C++ name mangling.

[Updated by Tony Luck to change efi.h:efi_freemem_callback_t to use
 u64 for start/end rather than unsigned long]

Subject: perf_counter: x86: Set the period in the intel overflow handler

Commit 9e350de37ac960 ("perf_counter: Accurate period data")
missed a spot, which caused all Intel-PMU samples to have a
period of 0.

This broke auto-freq sampling.

|    x86, apic: Fix dummy apic read operation together with broken MP handling
|

If we have apic disabled we don't even switch to APIC mode and do not
calling for connect_bsp_APIC. Though on SMP compiled kernel the
native_machine_shutdown does try to write the apic register anyway.

Fix it with explicit check if we really should touch apic registers.

Subject: ia64: Fix resource assignment for root busses

ia64 was assigning resources to root busses after allocations had
been made for child busses.  Calling pcibios_setup_root_windows() from
pcibios_fixup_bus() solves this problem by assigning the resources to
the root bus before child busses are scanned.

Subject: i386: fix return to 16-bit stack from NMI handler

Returning to a task with a 16-bit stack requires special care: the iret
instruction does not restore the high word of esp in that case. The
espfix code fixes this, but currently is not invoked on NMIs. This means
that a running task gets the upper word of esp clobbered due intervening
NMIs. To reproduce, compile and run the following program with the nmi
watchdog enabled (nmi_watchdog=2 on the command line). Using gdb you can
see that the high bits of esp contain garbage, while the low bits are
still correct.

This patch puts the espfix code back into the NMI code path.

The patch is slightly complicated due to the irqtrace infrastructure not
being NMI-safe. The NMI return path cannot call TRACE_IRQS_IRET.
Otherwise, the tail of the normal iret-code is correct for the nmi code
path too. To be able to share this code-path, the TRACE_IRQS_IRET was
move up a bit. The espfix code exists after the TRACE_IRQS_IRET, but
this code explicitly disables interrupts. This short interrupts-off
section is now not traced anymore. The return-to-kernel path now always
includes the preliminary test to decide if the espfix code should be
called. This is never the case, but doing it this way keeps the patch as
simple as possible and the few extra instructions should not affect
timing in any significant way.

Subject: i386: fix/simplify espfix stack switching, move it into assembly

The espfix code triggers if we have a protected mode userspace
application with a 16-bit stack. On returning to userspace, with iret,
the CPU doesn't restore the high word of the stack pointer. This is an
"official" bug, and the work-around used in the kernel is to temporarily
switch to a 32-bit stack segment/pointer pair where the high word of the
pointer is equal to the high word of the userspace stackpointer.

The current implementation uses THREAD_SIZE to determine the cut-off,
but there is no good reason not to use the more natural 64kb... However,
implementing this by simply substituting THREAD_SIZE with 65536 in
patch_espfix_desc crashed the test application. patch_espfix_desc tries
to do what is described above, but gets it subtly wrong if the userspace
stack pointer is just below a multiple of THREAD_SIZE: an overflow
occurs to bit 13... With a bit of luck, when the kernelspace
stackpointer is just below a 64kb-boundary, the overflow then ripples
trough to bit 16 and userspace will see its stack pointer changed by
65536.

This patch moves all espfix code into entry_32.S. Selecting a 16-bit
cut-off simplifies the code. The game with changing the limit dynamically
is removed too. It complicates matters and I see no value in it. Changing
only the top 16-bit word of ESP is one instruction and it also implies
that only two bytes of the ESPFIX GDT entry need to be changed and this
can be implemented in just a handful simple to understand instructions.
As a side effect, the operation to compute the original ESP from the
ESPFIX ESP and the GDT entry simplifies a bit too, and the remaining
three instructions have been expanded inline in entry_32.S.

impact: can now reliably run userspace with ESP=xxxxfffc on 16-bit
stack segment

Subject: x86: de-assembler-ize asm/desc.h

asm/desc.h is included in three assembly files, but the only macro
it defines, GET_DESC_BASE, is never used. This patch removes the
includes, removes the macro GET_DESC_BASE and the ASSEMBLY guard
from asm/desc.h.

Subject: sh: remove stray markers.

arch/sh has a couple of stray markers without any users introduced
in commit 3d58695edbfac785161bf282dc11fd42a483d6c9.  Remove them in
preparation of removing the markers in favour of the TRACE_EVENT
macro (and also because we don't keep dead code around).

From 105988c015943e77092a6568bc5fb7e386df6ccd Mon Sep 17 00:00:00 2001

Subject: perf_counter: powerpc: Enable use of software counters on 32-bit
 powerpc

This enables the perf_counter subsystem on 32-bit powerpc.  Since we
don't have any support for hardware counters on 32-bit powerpc yet,
only software counters can be used.

Besides selecting HAVE_PERF_COUNTERS for 32-bit powerpc as well as
64-bit, the main thing this does is add an implementation of
set_perf_counter_pending().  This needs to arrange for
perf_counter_do_pending() to be called when interrupts are enabled.
Rather than add code to local_irq_restore as 64-bit does, the 32-bit
set_perf_counter_pending() generates an interrupt by setting the
decrementer to 1 so that a decrementer interrupt will become pending
in 1 or 2 timebase ticks (if a decrementer interrupt isn't already
pending).  When interrupts are enabled, timer_interrupt() will be
called, and some new code in there calls perf_counter_do_pending().
We use a per-cpu array of flags to indicate whether we need to call
perf_counter_do_pending() or not.

This introduces a couple of new Kconfig symbols: PPC_HAVE_PMU_SUPPORT,
which is selected by processor families for which we have hardware PMU
support (currently only PPC64), and PPC_PERF_CTRS, which enables the
powerpc-specific perf_counter back-end.

Subject: perf_counter: powerpc: Use unsigned long for register and constraint
 values

This changes the powerpc perf_counter back-end to use unsigned long
types for hardware register values and for the value/mask pairs used
in checking whether a given set of events fit within the hardware
constraints.  This is in preparation for adding support for the PMU
on some 32-bit powerpc processors.  On 32-bit processors the hardware
registers are only 32 bits wide, and the PMU structure is generally
simpler, so 32 bits should be ample for expressing the hardware
constraints.  On 64-bit processors, unsigned long is 64 bits wide,
so using unsigned long vs. u64 (unsigned long long) makes no actual
difference.

This makes some other very minor changes: adjusting whitespace to line
things up in initialized structures, and simplifying some code in
hw_perf_disable().

Subject: perf_counter: powerpc: Change how processor-specific back-ends get
 selected

At present, the powerpc generic (processor-independent) perf_counter
code has list of processor back-end modules, and at initialization,
it looks at the PVR (processor version register) and has a switch
statement to select a suitable processor-specific back-end.

This is going to become inconvenient as we add more processor-specific
back-ends, so this inverts the order: now each back-end checks whether
it applies to the current processor, and registers itself if so.
Furthermore, instead of looking at the PVR, back-ends now check the
cur_cpu_spec->oprofile_cpu_type string and match on that.

Lastly, each back-end now specifies a name for itself so the core can
print a nice message when a back-end registers itself.

This doesn't provide any support for unregistering back-ends, but that
wouldn't be hard to do and would allow back-ends to be modules.

From 98fb1807b97e3e631b940f67544e265c64b984dc Mon Sep 17 00:00:00 2001
From: Paul Mackerras <paulus@samba.org>
Date: Wed, 17 Jun 2009 21:53:10 +1000
Subject: perf_counter: powerpc: Make powerpc perf_counter code safe for 32-bit
 kernels

This abstracts a few things in arch/powerpc/kernel/perf_counter.c
that are specific to 64-bit kernels, and provides definitions for
32-bit kernels.  In particular,

* Only 64-bit has MMCRA and the bits in it that give information
  about a PMU interrupt (sampled PR, HV, slot number etc.)
* Only 64-bit has the lppaca and the lppaca->pmcregs_in_use field
* Use of SDAR is confined to 64-bit for now
* Only 64-bit has soft/lazy interrupt disable and therefore
  pseudo-NMIs (interrupts that occur while interrupts are soft-disabled)
* Only 64-bit has PMC7 and PMC8
* Only 64-bit has the MSR_HV bit.

This also fixes the types used in a couple of places, where we were
using long types for things that need to be 64-bit.

From 7325927e5a20bfe0f006acf92801bf41c537d3d4 Mon Sep 17 00:00:00 2001
From: Paul Mackerras <paulus@samba.org>
Date: Wed, 17 Jun 2009 21:53:51 +1000
Subject: perf_counter: powerpc: Add processor back-end for MPC7450 family

This adds support for the performance monitor hardware on the
MPC7450 family of processors (7450, 7451, 7455, 7447/7457, 7447A,
7448), used in the later Apple G4 powermacs/powerbooks and other
machines.  These machines have 6 hardware counters with a unique
set of events which can be counted on each counter, with some
events being available on multiple counters.

Raw event codes for these processors are (PMC << 8) + PMCSEL.
If PMC is non-zero then the event is that selected by the given
PMCSEL value for that PMC (hardware counter).  If PMC is zero
then the event selected is one of the low-numbered ones that are
common to several PMCs.  In this case PMCSEL must be <= 22 and
the event is what that PMCSEL value would select on PMC1 (but
it may be placed any other PMC that has the same event for that
PMCSEL value).

For events that count cycles or occurrences that exceed a threshold,
the threshold requested can be specified in the 0x3f000 bits of the
raw event codes.  If the event uses the threshold multiplier bit
and that bit should be set, that is indicated with the 0x40000 bit
of the raw event code.

This fills in some of the generic cache events.  Unfortunately there
are quite a few blank spaces in the table, partly because these
processors tend to count cache hits rather than cache accesses.

Subject: sh: Fix declaration of __kernel_sigreturn and __kernel_rt_sigreturn

GCC 4.5.0 complains about the declaration of variables
__kernel_sigreturn and __kernel_rt_sigreturn because they have type
void.  Correctly declare these symbols as functions to fix the
following error,

arch/sh/kernel/signal_32.c: In function 'setup_frame':
arch/sh/kernel/signal_32.c:368:14: error: taking address of expression of type 'void'
arch/sh/kernel/signal_32.c: In function 'setup_rt_frame':
arch/sh/kernel/signal_32.c:452:14: error: taking address of expression of type 'void'
make[1]: *** [arch/sh/kernel/signal_32.o] Error 1
make: *** [arch/sh/kernel] Error 2

Subject: crypto: aes-ni - Do not sleep when using the FPU

Because AES-NI instructions will touch XMM state, corresponding code
must be enclosed within kernel_fpu_begin/end, which used
preempt_disable/enable. So sleep should be prevented between
kernel_fpu_begin/end.

Subject: gcov: add gcov profiling infrastructure

Enable the use of GCC's coverage testing tool gcov [1] with the Linux
kernel.  gcov may be useful for:

 * debugging (has this code been reached at all?)
 * test improvement (how do I change my test to cover these lines?)
 * minimizing kernel configurations (do I need this option if the
   associated code is never run?)

The profiling patch incorporates the following changes:

 * change kbuild to include profiling flags
 * provide functions needed by profiling code
 * present profiling data as files in debugfs

Note that on some architectures, enabling gcc's profiling option
"-fprofile-arcs" for the entire kernel may trigger compile/link/
run-time problems, some of which are caused by toolchain bugs and
others which require adjustment of architecture code.

For this reason profiling the entire kernel is initially restricted
to those architectures for which it is known to work without changes.
This restriction can be lifted once an architecture has been tested
and found compatible with gcc's profiling. Profiling of single files
or directories is still available on all platforms (see config help
text).

+Using gcov with the Linux kernel
+================================
+
+1. Introduction
+2. Preparation
+3. Customization
+4. Files
+5. Modules
+6. Separated build and test machines
+7. Troubleshooting
+Appendix A: sample script: gather_on_build.sh
+Appendix B: sample script: gather_on_test.sh
+
+
+1. Introduction
+===============
+
+gcov profiling kernel support enables the use of GCC's coverage testing
+tool gcov [1] with the Linux kernel. Coverage data of a running kernel
+is exported in gcov-compatible format via the "gcov" debugfs directory.
+To get coverage data for a specific file, change to the kernel build
+directory and use gcov with the -o option as follows (requires root):
+
+# cd /tmp/linux-out
+# gcov -o /sys/kernel/debug/gcov/tmp/linux-out/kernel spinlock.c
+
+This will create source code files annotated with execution counts
+in the current directory. In addition, graphical gcov front-ends such
+as lcov [2] can be used to automate the process of collecting data
+for the entire kernel and provide coverage overviews in HTML format.
+
+Possible uses:
+
+* debugging (has this line been reached at all?)
+* test improvement (how do I change my test to cover these lines?)
+* minimizing kernel configurations (do I need this option if the
+  associated code is never run?)
+
+--
+
+[1] http://gcc.gnu.org/onlinedocs/gcc/Gcov.html
+[2] http://ltp.sourceforge.net/coverage/lcov.php
+
+
+2. Preparation
+==============
+
+Configure the kernel with:
+
+        CONFIG_DEBUGFS=y
+        CONFIG_GCOV_KERNEL=y
+
+and to get coverage data for the entire kernel:
+
+        CONFIG_GCOV_PROFILE_ALL=y
+
+Note that kernels compiled with profiling flags will be significantly
+larger and run slower. Also CONFIG_GCOV_PROFILE_ALL may not be supported
+on all architectures.
+
+Profiling data will only become accessible once debugfs has been
+mounted:
+
+        mount -t debugfs none /sys/kernel/debug
+
+
+3. Customization
+================
+
+To enable profiling for specific files or directories, add a line
+similar to the following to the respective kernel Makefile:
+
+        For a single file (e.g. main.o):
+                GCOV_PROFILE_main.o := y
+
+        For all files in one directory:
+                GCOV_PROFILE := y
+
+To exclude files from being profiled even when CONFIG_GCOV_PROFILE_ALL
+is specified, use:
+
+                GCOV_PROFILE_main.o := n
+        and:
+                GCOV_PROFILE := n
+
+Only files which are linked to the main kernel image or are compiled as
+kernel modules are supported by this mechanism.
+
+
+4. Files
+========
+
+The gcov kernel support creates the following files in debugfs:
+
+        /sys/kernel/debug/gcov
+                Parent directory for all gcov-related files.
+
+        /sys/kernel/debug/gcov/reset
+                Global reset file: resets all coverage data to zero when
+                written to.
+
+        /sys/kernel/debug/gcov/path/to/compile/dir/file.gcda
+                The actual gcov data file as understood by the gcov
+                tool. Resets file coverage data to zero when written to.
+
+        /sys/kernel/debug/gcov/path/to/compile/dir/file.gcno
+                Symbolic link to a static data file required by the gcov
+                tool. This file is generated by gcc when compiling with
+                option -ftest-coverage.
+
+
+5. Modules
+==========
+
+Kernel modules may contain cleanup code which is only run during
+module unload time. The gcov mechanism provides a means to collect
+coverage data for such code by keeping a copy of the data associated
+with the unloaded module. This data remains available through debugfs.
+Once the module is loaded again, the associated coverage counters are
+initialized with the data from its previous instantiation.
+
+This behavior can be deactivated by specifying the gcov_persist kernel
+parameter:
+
+        gcov_persist=0
+
+At run-time, a user can also choose to discard data for an unloaded
+module by writing to its data file or the global reset file.
+
+
+6. Separated build and test machines
+====================================
+
+The gcov kernel profiling infrastructure is designed to work out-of-the
+box for setups where kernels are built and run on the same machine. In
+cases where the kernel runs on a separate machine, special preparations
+must be made, depending on where the gcov tool is used:
+
+a) gcov is run on the TEST machine
+
+The gcov tool version on the test machine must be compatible with the
+gcc version used for kernel build. Also the following files need to be
+copied from build to test machine:
+
+from the source tree:
+  - all C source files + headers
+
+from the build tree:
+  - all C source files + headers
+  - all .gcda and .gcno files
+  - all links to directories
+
+It is important to note that these files need to be placed into the
+exact same file system location on the test machine as on the build
+machine. If any of the path components is symbolic link, the actual
+directory needs to be used instead (due to make's CURDIR handling).
+
+b) gcov is run on the BUILD machine
+
+The following files need to be copied after each test case from test
+to build machine:
+
+from the gcov directory in sysfs:
+  - all .gcda files
+  - all links to .gcno files
+
+These files can be copied to any location on the build machine. gcov
+must then be called with the -o option pointing to that directory.
+
+Example directory setup on the build machine:
+
+  /tmp/linux:    kernel source tree
+  /tmp/out:      kernel build directory as specified by make O=
+  /tmp/coverage: location of the files copied from the test machine
+
+  [user@build] cd /tmp/out
+  [user@build] gcov -o /tmp/coverage/tmp/out/init main.c
+
+
+7. Troubleshooting
+==================
+
+Problem:  Compilation aborts during linker step.
+Cause:    Profiling flags are specified for source files which are not
+          linked to the main kernel or which are linked by a custom
+          linker procedure.
+Solution: Exclude affected source files from profiling by specifying
+          GCOV_PROFILE := n or GCOV_PROFILE_basename.o := n in the
+          corresponding Makefile.
+
+
+Appendix A: gather_on_build.sh
+==============================
+
+Sample script to gather coverage meta files on the build machine
+(see 6a):
+
+#!/bin/bash
+
+KSRC=$1
+KOBJ=$2
+DEST=$3
+
+if [ -z "$KSRC" ] || [ -z "$KOBJ" ] || [ -z "$DEST" ]; then
+  echo "Usage: $0 <ksrc directory> <kobj directory> <output.tar.gz>" >&2
+  exit 1
+fi
+
+KSRC=$(cd $KSRC; printf "all:\n\t@echo \${CURDIR}\n" | make -f -)
+KOBJ=$(cd $KOBJ; printf "all:\n\t@echo \${CURDIR}\n" | make -f -)
+
+find $KSRC $KOBJ \( -name '*.gcno' -o -name '*.[ch]' -o -type l \) -a \
+                 -perm /u+r,g+r | tar cfz $DEST -P -T -
+
+if [ $? -eq 0 ] ; then
+  echo "$DEST successfully created, copy to test system and unpack with:"
+  echo "  tar xfz $DEST -P"
+else
+  echo "Could not create file $DEST"
+fi
+
+
+Appendix B: gather_on_test.sh
+=============================
+
+Sample script to gather coverage data files on the test machine
+(see 6b):
+
+#!/bin/bash
+
+DEST=$1
+GCDA=/sys/kernel/debug/gcov
+
+if [ -z "$DEST" ] ; then
+  echo "Usage: $0 <output.tar.gz>" >&2
+  exit 1
+fi
+
+find $GCDA -name '*.gcno' -o -name '*.gcda' | tar cfz $DEST -T -
+
+if [ $? -eq 0 ] ; then
+  echo "$DEST successfully created, copy to build system and unpack with:"
+  echo "  tar xfz $DEST"
+else
+  echo "Could not create file $DEST"

+
+	For all files in one directory:

+	and:
+	        GCOV_PROFILE := n

Subject: gcov: enable GCOV_PROFILE_ALL for x86_64

Enable gcov profiling of the entire kernel on x86_64. Required changes
include disabling profiling for:

* arch/kernel/acpi/realmode and arch/kernel/boot/compressed:
  not linked to main kernel
* arch/vdso, arch/kernel/vsyscall_64 and arch/kernel/hpet:
  profiling causes segfaults during boot (incompatible context)

From: Steven Rostedt <srostedt@redhat.com>

Subject: function-graph: add stack frame test

In case gcc does something funny with the stack frames, or the return
from function code, we would like to detect that.

An arch may implement passing of a variable that is unique to the
function and can be saved on entering a function and can be tested
when exiting the function. Usually the frame pointer can be used for
this purpose.

This patch also implements this for x86. Where it passes in the stack
frame of the parent function, and will test that frame on exit.

There was a case in x86_32 with optimize for size (-Os) where, for a
few functions, gcc would align the stack frame and place a copy of the
return address into it. The function graph tracer modified the copy and
not the actual return address. On return from the funtion, it did not go
to the tracer hook, but returned to the parent. This broke the function
graph tracer, because the return of the parent (where gcc did not do
this funky manipulation) returned to the location that the child function
was suppose to. This caused strange kernel crashes.

This test detected the problem and pointed out where the issue was.

This modifies the parameters of one of the functions that the arch
specific code calls, so it includes changes to arch code to accommodate
the new prototype.

Note, I notice that the parsic arch implements its own push_return_trace.
This is now a generic function and the ftrace_push_return_trace should be
used instead. This patch does not touch that code.

Convert to test_bit() as that is what pretty much everyone uses and allows

Subject: Blackfin: pull in asm/io.h in ksyms for prototypes

Make sure we pull in asm/io.h when exporting symbols for the I/O functions
so we don't end up with a build failure due to missing prototypes.

Subject: Blackfin: only build irqpanic.c when needed

The irq_panic function is only used when CONFIG_DEBUG_ICACHE_CHECK is
enabled, so move the conditional build to the Makefile rather than
wrapping all of the contents of the file.

-/* Core file format: The core file is written in such a way that gdb

-   obstacles to being able to view the contents of the floating point
-   registers, and until these are solved you will not be able to view the
-   contents of them.  Actually, you can read in the core file and look at
-   the contents of the user struct to find out what the floating point
-   registers contain.
-   The actual file contents are as follows:
-   UPAGE: 1 page consisting of a user struct that tells gdb what is present
-   in the file.  Directly after this is a copy of the task_struct, which
-   is currently not used by gdb, but it may come in useful at some point.
-   All of the registers are stored as part of the upage.  The upage should
-   always be only one page.
-   DATA: The data area is stored.  We use current->end_text to
-   current->brk to pick up all of the user variables, plus any memory
-   that may have been malloced.  No attempt is made to determine if a page
-   is demand-zero or if a page is totally unused, we just cover the entire
-   range.  All of the addresses are rounded in such a way that an integral
-   number of pages is written.
-   STACK: We need the stack information in order to get a meaningful
-   backtrace.  We need to write the data from (esp) to
-   current->start_stack, so we round each of these off in order to be able
-   to write an integer number of pages.
-   The minimum core file size is 3 pages, or 12288 bytes.

Subject: sparc64: Fix UP bootup regression.

Commit b696fdc259f0d94348a9327bed352fac44d4883d ("sparc64: Defer
cpu_data() setup until end of per-cpu data initialization.") broke
bootup for UP builds because the cpu_data() initialization only
occurs in setup_per_cpu_areas() which is never compiled in nor
called in UP builds.

Fix this up by calling the setups directly from init_64.c when
non-SMP.

Subject: perf_counter: Make callchain samples extensible

Before exposing upstream tools to a callchain-samples ABI, tidy it
up to make it more extensible in the future:

Use markers in the IP chain to denote context, use (u64)-1..-4095 range
for these context markers because we use them for ERR_PTR(), so these
addresses are unlikely to be mapped.

Subject: perf_counter, x86: Improve interactions with fast-gup

Improve a few details in perfcounter call-chain recording that
makes use of fast-GUP:

- Use ACCESS_ONCE() to observe the pte value. ptes are fundamentally
  racy and can be changed on another CPU, so we have to be careful
  about how we access them. The PAE branch is already careful with
  read-barriers - but the non-PAE and 64-bit side needs an
  ACCESS_ONCE() to make sure the pte value is observed only once.

- make the checks a bit stricter so that we can feed it any kind of
  cra^H^H^H user-space input ;-)

Add alignment fault fixup support for 32-bit Thumb-2 LDM, LDRD, POP,
PUSH, STM and STRD instructions.  Alignment fault fixup support for
the remaining 32-bit Thumb-2 load/store instruction cases is not
included since ARMv6 and later processors include hardware support
for loads and stores of unaligned words and halfwords.

Subject: [ARM] 5558/1: Add extra checks to ARM unwinder to avoid tracing
 corrupt stacks

There are situations where the unwinder goes beyond stack boundaries and
unwinds random data. This patch moves the stack boundaries check after
the unwind_exec_insn() call and adds an extra check for possible
infinite loops (like "mov pc, lr" with pc == lr).

The patch also fixes a bug in the unwind instructions interpreter. The
0xb0 instruction can only set PC to LR if this wasn't already set by
a previous instruction (this is used on exceptions taken while in kernel
mode where svc_entry is annotated with ".save {r0 - pc}").

Subject: [ARM] 5559/1: Limit the stack unwinding caused by a kthread exit

When a kthread function returns, it branches to do_exit(). However, the
unwinding information isn't valid anymore and any stack trace caused by
do_exit() may be incorrect. This patch adds a kernel_thread_exit()
function and annotated with '.cantunwind' so that the unwinder stops
when reaching it.

Subject: OMAP3 clock: add a short delay when lowering CORE clk rate

When changing the SDRAM clock from 166MHz to 83MHz via the CORE DPLL M2
divider, add a short delay before returning to SDRAM to allow the SDRC
time to stabilize.  Without this delay, the system is prone to random
panics upon re-entering SDRAM.

This time delay varies based on MPU frequency.  At 500MHz MPU frequency at
room temperature, 64 loops seems to work okay; so add another 32 loops for
environmental and process variation.

Subject: OMAP3 clock/SDRC: program SDRC_MR register during SDRC clock change

Program the SDRC_MR_0 register as well during SDRC clock changes.
This register allows selection of the memory CAS latency.  Some SDRAM
chips, such as the Qimonda HYB18M512160AF6, have a lower CAS latency
at lower clock rates.

Subject: OMAP3 SDRC: set FIXEDDELAY when disabling SDRC DLL

Correspondence with the TI OMAP hardware team indicates that
SDRC_DLLA_CTRL.FIXEDDELAY should be initialized to 0x0f.  This number
was apparently derived from process validation.  This is only used
when the SDRC DLL is unlocked (e.g., SDRC clock frequency less than
83MHz).

Subject: ACPI: pdc init related memory leak with physical CPU hotplug

arch_acpi_processor_cleanup_pdc() in x86 and ia64 results in memory allocated
for _PDC objects that is never freed and will cause memory leak in case of
physical CPU remove and add. Patch fixes the memory leak by freeing the
objects soon after _PDC is evaluated.

Subject: microblaze: remove init_mm

Alexey removed the definition for init_mm from all architectures
but forgot microblaze, which was only recently added.
This fixes the microblaze build by dropping it there as well.

Subject: x86: don't use 'access_ok()' as a range check in
 get_user_pages_fast()

It's really not right to use 'access_ok()', since that is meant for the
normal "get_user()" and "copy_from/to_user()" accesses, which are done
through the TLB, rather than through the page tables.

Why? access_ok() does both too few, and too many checks.  Too many,
because it is meant for regular kernel accesses that will not honor the
'user' bit in the page tables, and because it honors the USER_DS vs
KERNEL_DS distinction that we shouldn't care about in GUP.  And too few,
because it doesn't do the 'canonical' check on the address on x86-64,
since the TLB will do that for us.

So instead of using a function that isn't meant for this, and does
something else and much more complicated, just do the real rules: we
don't want the range to overflow, and on x86-64, we want it to be a
canonical low address (on 32-bit, all addresses are canonical).

Subject: x86, 64-bit: Clean up user address masking

The discussion about using "access_ok()" in get_user_pages_fast() (see
commit 7f8189068726492950bf1a2dcfd9b51314560abf: "x86: don't use
'access_ok()' as a range check in get_user_pages_fast()" for details and
end result), made us notice that x86-64 was really being very sloppy
about virtual address checking.

So be way more careful and straightforward about masking x86-64 virtual
addresses:

 - All the VIRTUAL_MASK* variants now cover half of the address
   space, it's not like we can use the full mask on a signed
   integer, and the larger mask just invites mistakes when
   applying it to either half of the 48-bit address space.

 - /proc/kcore's kc_offset_to_vaddr() becomes a lot more
   obvious when it transforms a file offset into a
   (kernel-half) virtual address.

 - Unify/simplify the 32-bit and 64-bit USER_DS definition to
   be based on TASK_SIZE_MAX.

This cleanup and more careful/obvious user virtual address checking also
uncovered a buglet in the x86-64 implementation of strnlen_user(): it
would do an "access_ok()" check on the whole potential area, even if the
string itself was much shorter, and thus return an error even for valid
strings. Our sloppy checking had hidden this.

So this fixes 'strnlen_user()' to do this properly, the same way we
already handled user strings in 'strncpy_from_user()'.  Namely by just
checking the first byte, and then relying on fault handling for the
rest.  That always works, since we impose a guard page that cannot be
mapped at the end of the user space address space (and even if we
didn't, we'd have the address space hole).

Subject: x86: Set cpu_llc_id on AMD CPUs

This counts when building sched domains in case NUMA information
is not available.

( See cpu_coregroup_mask() which uses llc_shared_map which in turn is
  created based on cpu_llc_id. )

Currently Linux builds domains as follows:
(example from a dual socket quad-core system)

 CPU0 attaching sched-domain:
  domain 0: span 0-7 level CPU
   groups: 0 1 2 3 4 5 6 7

  ...

 CPU7 attaching sched-domain:
  domain 0: span 0-7 level CPU
   groups: 7 0 1 2 3 4 5 6

Ever since that is borked for multi-core AMD CPU systems.
This patch fixes that and now we get a proper:

 CPU0 attaching sched-domain:
  domain 0: span 0-3 level MC
   groups: 0 1 2 3
   domain 1: span 0-7 level CPU
    groups: 0-3 4-7

  ...

 CPU7 attaching sched-domain:
  domain 0: span 4-7 level MC
   groups: 7 4 5 6
   domain 1: span 0-7 level CPU
    groups: 4-7 0-3

This allows scheduler to assign tasks to cores on different sockets
(i.e. that don't share last level cache) for performance reasons.

From d06063cc221fdefcab86589e79ddfdb7c0e14b63 Mon Sep 17 00:00:00 2001
From: Linus Torvalds <torvalds@linux-foundation.org>
Date: Fri, 10 Apr 2009 09:01:23 -0700
Subject: Move FAULT_FLAG_xyz into handle_mm_fault() callers

This allows the callers to now pass down the full set of FAULT_FLAG_xyz
flags to handle_mm_fault().  All callers have been (mechanically)
converted to the new calling convention, there's almost certainly room
for architectures to clean up their code and then add FAULT_FLAG_RETRY
when that support is added.

In the failure path, setup_pcpu_remap() tries to free the area which
has already been freed to make holes in the large page.  Fix it.

Subject: x86: rename remap percpu first chunk allocator to lpage

The "remap" allocator remaps large pages to build the first chunk;
however, the name isn't very good because 4k allocator remaps too and
the whole point of the remap allocator is using large page mapping.
The allocator will be generalized and exported outside of x86, rename
it to lpage before that happens.

percpu_alloc kernel parameter is updated to accept both "remap" and
"lpage" for lpage allocator.

[ Impact: code cleanup, kernel parameter argument updated ]

Make the following changes in preparation of coming pageattr updates.

* Define and use array of struct pcpul_ent instead of array of
  pointers.  The only difference is ->cpu field which is set but
  unused yet.

* Rename variables according to the above change.

* Rename local variable vm to pcpul_vm and move it out of the
  function.

Subject: x86: fix pageattr handling for lpage percpu allocator and re-enable
 it

lpage allocator aliases a PMD page for each cpu and returns whatever
is unused to the page allocator.  When the pageattr of the recycled
pages are changed, this makes the two aliases point to the overlapping
regions with different attributes which isn't allowed and known to
cause subtle data corruption in certain cases.

This can be handled in simliar manner to the x86_64 highmap alias.
pageattr code should detect if the target pages have PMD alias and
split the PMD alias and synchronize the attributes.

pcpur allocator is updated to keep the allocated PMD pages map sorted
in ascending address order and provide pcpu_lpage_remapped() function
which binary searches the array to determine whether the given address
is aliased and if so to which address.  pageattr is updated to use
pcpu_lpage_remapped() to detect the PMD alias and split it up as
necessary from cpa_process_alias().

Jan Beulich spotted the original problem and incorrect usage of vaddr
instead of laddr for lookup.

With this, lpage percpu allocator should work correctly.  Re-enable
it.

Subject: x86: implement percpu_alloc kernel parameter

According to Andi, it isn't clear whether lpage allocator is worth the
trouble as there are many processors where PMD TLB is far scarcer than
PTE TLB.  The advantage or disadvantage probably depends on the actual
size of percpu area and specific processor.  As performance
degradation due to TLB pressure tends to be highly workload specific
and subtle, it is difficult to decide which way to go without more
data.

This patch implements percpu_alloc kernel parameter to allow selecting
which first chunk allocator to use to ease debugging and testing.

While at it, make sure all the failure paths report why something
failed to help determining why certain allocator isn't working.  Also,
kill the "Great future plan" comment which had already been realized
quite some time ago.

[ Impact: allow explicit percpu first chunk allocator selection ]

Subject: x86: ensure percpu lpage doesn't consume too much vmalloc space

On extreme configuration (e.g. 32bit 32-way NUMA machine), lpage
percpu first chunk allocator can consume too much of vmalloc space.
Make it fall back to 4k allocator if the consumption goes over 20%.

[ Impact: add sanity check for lpage percpu first chunk allocator ]

Subject: xtensa: allow variant to initialize own irq chips
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There was already a PLATFORM_NR_IRQS define, which is now accompanied
by a VARIANT_NR_IRQS. To be able to initialize these interrupts,
init_IRQ now calls a variant specific hook.

Changes compared to v1:
- adapted to new CONFIG_VARIANT_IRQ_EXT
- removed definition and call of platform_init_IRQ as there already
  is a platform_init_irq defined in asm/platform.h with a weak default
  in kernel/platform.c
- renamed variant_init_IRQ to variant_init_irq

Note that I could not find the call site of platform_init_irq although
it is stated in platform.h that it is called from init_IRQ.

From f24e552c2dc3221dc7bd2296fd8a705283c4b2d7 Mon Sep 17 00:00:00 2001
From: Oskar Schirmer <os@emlix.com>

Subject: xtensa: s6000 dma engine support

There are four slightly different dma engines on the s6000 family.
One for memory-memory transfers, the other three for memory-device.

This patch implements a platform-specific kernel-API to control these
engines.  It is needed for the network, video, audio peripherals on
s6000.

From 0b3eb21b2f2222c4c1e3e21fc3cd427404d3991a Mon Sep 17 00:00:00 2001
From: Daniel Glöckner <dg@emlix.com>
Date: Tue, 5 May 2009 15:03:22 +0000
Subject: xtensa: support s6000 gpio irqs and alternate function selection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement an irq chip to handle interrupts via gpio.  The GPIO chip
initialization function now takes a bitmask denoting pins that should
be configured for their alternate function.

changes compared to v1:
- fixed bug on edge interrupt configuration
- accommodated to function name change
- moved definition of VARIANT_NR_IRQS to this patch
- renamed __XTENSA_S6000_IRQ_H to _XTENSA_S6000_IRQ_H as requested

Subject: [S390] s390: remove DEBUG_MALLOC

The kernel now has kmemleak and kmemtrace so there's no reason to keep
this ugly s390 hack around. I am not sure how it's supposed to work on
SMP anyway as it uses a global variable to temporarily store the return
value of all kmalloc() calls:

  void *b;

  #define kmalloc(x...) (PRINT_INFO(" kmalloc %p\n",b=kmalloc(x)),b)

Remove unneeded sanity checks from do_QDIO since this is the hot path.
Change the type of bufnr and count to unsigned int so the check for the
maximum value works.

Subject: [S390] kprobes: defer setting of ctlblk state

get_krobe_ctlblk returns a per cpu kprobe control block which holds
the state of the current cpu wrt to kprobe.
When inserting/removing a kprobe the state of the cpu which replaces
the code is changed to KPROBE_SWAP_INST. This however is done when
preemption is still enabled. So the state of the current cpu doesn't
necessarily reflect the real state.
To fix this move the code that changes the state to non-preemptible
context.

A few typos seems to have sneaked into the HCLK gate defines, causing the
usb host clock to not get enabled. Fix them according to the reference
manual and throw in the 3d accel bit for good measure.

Subject: [ARM] S3C: Fix gpio-config off-by-one bug

Fix gpio-config off-by-one bug. Without this patch, touching GPA0 pin on
S3C64XX platform causes kernel oops.

Subject: [ARM] idle: clean up pm_idle calling, obey hlt_counter

pm_idle is used by infrastructure (eg, cpuidle) which expects architectures
to call it in a certain way.  Arrange for ARM to follow x86's lead on this
and call pm_idle() with interrupts already disabled.  However, we expect
pm_idle() to enable interrupts before it returns.

Also, OMAP wants to be able to disable hlt-ing, so allow hlt_counter to
prevent all calls to pm_idle.

Subject: Blackfin: unify memory region checks between kgdb and traps

The kgdb (in multiple places) and traps code developed pretty much
identical checks for how to access different regions of the Blackfin
memory map, but each wasn't 100%, so unify them to avoid duplication,
bitrot, and bugs with edge cases.

Subject: Blackfin: redo handling of bad irqs

With the common IRQ code initializing much more of the irq_desc state, we
can't blindly initialize it ourselves to the local bad_irq state.  If we
do, we end up wrongly clobbering many fields.  So punt most of the bad irq
code as the common layers will handle the default state, and simply call
handle_bad_irq() directly when the IRQ we are processing is invalid.

Subject: Blackfin: fix accidental reset in some boot modes

We read the SWRST (Software Reset) register to get at the last reset
state, and then we may configure the DOUBLE_FAULT bit to control behavior
when a double fault occurs.  But if the lower bits of the register is
already set (like UART boot mode on a BF54x), we inadvertently make the
system reset by writing to the SYSTEM_RESET field at the same time.  So
make sure the lower 4 bits are always cleared.

Subject: Blackfin: decouple unrelated cache settings to get exact behavior

The current cache options don't really represent the hardware features.
They end up setting different aspects of the hardware so that the end
result is to turn on/off the cache.  Unfortunately, when we hit cache
problems with the hardware, it's difficult to test different settings to
root cause the problem.  The current settings also don't cleanly allow for
different caching behaviors with different regions of memory.

So split the configure options such that they properly reflect the settings
that are applied to the hardware.

Subject: Blackfin: stick the CPU name into boot image name

Rather than use "Linux" in the boot image name (as this is redundant --
the image type is already set to "linux"), use the CPU name.  This makes
it fairly obvious when a wrong image is accidentally booted.  Otherwise
there is no kernel output and you waste time scratching your head
wondering wtf just happened.

Subject: Blackfin: unify memory map headers

Many aspects of the Blackfin memory map is exactly the same across all
variants.  Rather than copy and paste all of these duplicated values in
each header, unify all of these into the common Blackfin memory map header
file.  In the process, push down BF561 SMP specific stuff to the BF561
specific header to keep the noise down.

Subject: Blackfin: fix early crash when booting on wrong cpu

Make sure we process the kernel command line before poking the hardware,
so that we can process early printk.  This helps ensure that if you boot
a kernel configured for a different processor, something will be left in
the log buffer.

punt it to keep the noise down.

Subject: Blackfin: fix dma-mapping build errors

The recent deprecation of dma_sync_{sg,single} ironically broke Blackfin
systems.  This is because we don't define dma_sync_sg_for_cpu at all, so
until the DMA asm-generic conversion/cleanup is done after the next
release, simply stub out the dma_sync_sg_for_{cpu,device} functions.

at this point, switch to the local_ variant so the flush happens on the

Subject: x86: Move init_gbpages() to setup_arch()

The init_gbpages() function is conditionally called from
init_memory_mapping() function. There are two call-sites where
this 'after_bootmem' condition can be true: setup_arch() and
mem_init() via pci_iommu_alloc().

Therefore, it's safe to move the call to init_gbpages() to
setup_arch() as it's always called before mem_init().

This removes an after_bootmem use - paving the way to remove
all uses of that state variable.

Subject: OMAP1: Fix N770 MMC support

Some of the N770's MMC configuration options seem to have been
dropped. This patch adds them back in again.

Note that only the .ocr_mask change was /critical/, but I've added the
.max_freq setting back as well, as the original sources had it. Can
anyone confirm if this is unnecessary?

Secondly, there is support in the original code for a 4wire/higher
speed mode. As I don't have the requisite N770 hardware (I think it
was a rev2 N770?) to test this, I can't really add it back.

Subject: OMAP2/3: Add omap_type() for determining GP/EMU/HS

The omap_type() function is added and returns the DEVICETYPE field of
the CONTROL_STATUS register.  The result can be used for conditional
code based on whether device is GP (general purpose), EMU or
HS (high security). Also move the type defines so omap1 code
compile does not require ifdefs for sections using these defines.

This code is needed for the following fix to set the SRAM
size correctly for HS omaps.  Also at least PM and watchdog
code will need this function.

CONFIG_S3C24XX_PWM was defined in arch/arm/plat-s3c24xx/Kconfig but
not used anywhere else as the corresponding makefile used
CONFIG_HAVE_PWM (selected by CONFIG_S3C24XX_PWM) to compile the PWM
driver.

Change the makefile to use CONFIG_S3C24XX_PWM to compile this driver
to ensure it is only build when needed.

Subject: ARM: add support for the EET board, based on the i.MX31 pcm037 module

The "EET" variant of the pcm037 board has an OLED display, using a S6E63D6
display controller on the first SPI interface, using GPIO57 as a chip-select
for it. S6E63D6 is initialised in the boot-loader, so we only have to take care
of the LCD. EET also adds several buttons and LEDs on GPIOs. This patch adds a
"pcm037_variant=" kernel command line parameter to specify at boot-time which
board the kernel is running on, default is "pcm970", specify "eet" for the EET
board.

Subject: powerpc/qe: add polling timeout to qe_issue_cmd()

The qe_issue_cmd() function (Freescale PowerPC QUICC Engine library) polls
on a register until a status bit changes, but does not include a timeout
to handle the situation if the bit never changes.  Change the code to use
the new spin_event_timeout() macro, which simplifies polling on a register
without a timeout.

Subject: powerpc/85xx: Make eSDHC 1-bit only transfer mode default for
 MPC8569E-MDS

For yet unknown reason 4-bit mode doesn't work on MPC8569E-MDS boards,
so make 1-bit mode default. When we resolve the issue, u-boot will
remove sdhci,1-bit-only property from the device tree, while SDHCI
will still work with older u-boots.

Commit 52da219e9664e537a745877b0efa7cf2b1ff2996 removed
the s3c_device_iis, but didn't replace it with anything
so a number of s3c24xx machines are currently failing
to build.

As a temporary fix, re-instate s3c_device_iis until a
proper replacement can be done for it.

Subject: [ARM] S3C: Fix S3C24XX build to not include s3c64xx IIS devices

Commit 52da219e9664e537a745877b0efa7cf2b1ff2996 added IIS
platform devices, but these do not build on s3c24xx systems
and the file depends on SND_S3C24XX_SOC, which is selected
for all S3C64XX/S3C24XX systems.

As a quick fix, make the dev-audio.o file depends on
SND_S3C64XX_SOC_I2S instead.

Subject: Intel-IOMMU, intr-remap: source-id checking

To support domain-isolation usages, the platform hardware must be
capable of uniquely identifying the requestor (source-id) for each
interrupt message. Without source-id checking for interrupt remapping
, a rouge guest/VM with assigned devices can launch interrupt attacks
to bring down anothe guest/VM or the VMM itself.

This patch adds source-id checking for interrupt remapping, and then
really isolates interrupts for guests/VMs with assigned devices.

Because PCI subsystem is not initialized yet when set up IOAPIC
entries, use read_pci_config_byte to access PCI config space directly.

Subject: [ARM] GTA02: build fixes (s3c2410_nand_set usage)

This patch fixes two errors we get when building GTA02 kernel.

~ use_bbt is incorrect, we need flash_bbt.

~ We do not need .force_soft_ecc because we can unset
  CONFIG_MTD_NAND_S3C2410_HWECC.

Subject: perf_counter, x86: Set global control MSR correctly

Previous code made an assumption that the power on value of global
control MSR has enabled all fixed and general purpose counters properly.

However, this is not the case for certain Intel processors, such as
Atom - and it might also be firmware dependent.

Each enable bit in IA32_PERF_GLOBAL_CTRL is AND'ed with the
enable bits for all privilege levels in the respective IA32_PERFEVTSELx
or IA32_PERF_FIXED_CTR_CTRL MSRs to start/stop the counting of
respective counters. Counting is enabled if the AND'ed results is true;
counting is disabled when the result is false.

The end result is that all fixed counters are always disabled on Atom
processors because the assumption is just invalid.

Fix this by not initializing the ctrl-mask out of the global MSR,
but setting it to perf_counter_mask.

Subject: x86: Fix uv bau sending buffer initialization

The initialization of the UV Broadcast Assist Unit's sending
buffers was making an invalid assumption about the
initialization of an MMR that defines its address.

The BIOS will not be providing that MMR.  So
uv_activation_descriptor_init() should unconditionally set it.

Tested on UV simulator.

Some of the were relying into smp.h being dragged in by another header
which of course is fragile.  <asm/cpu-info.h> uses smp_processor_id()
only in macros and including smp.h there leads to an include loop, so
don't change cpu-info.h.

From 44eeab67416711db9b84610ef18c99a60415dff8 Mon Sep 17 00:00:00 2001

Subject: MIPS: Hibernation: Remove SMP TLB and cacheflushing code.

We can't perform any flushes on SMP from swsusp_arch_resume because
interrupts are disabled.  A cross-CPU flush is unnecessary anyway
because all but the local CPU have already been disabled.  A local
flush is not needed either because we didn't change any mappings.  So
just delete the code.

From: Ralf Baechle <ralf@linux-mips.org>
Date: Tue, 23 Jun 2009 10:00:31 +0100
Subject: MIPS: Add arch generic CPU hotplug

Each platform has to add support for CPU hotplugging itself by providing
suitable definitions for the cpu_disable and cpu_die of the smp_ops
methods and setting SYS_SUPPORTS_HOTPLUG_CPU.  A platform should only set
SYS_SUPPORTS_HOTPLUG_CPU once all it's smp_ops definitions have the
necessary changes.  This patch contains the changes to the dummy smp_ops
definition for uni-processor systems.

Parts of the code contributed by Cavium Inc.

Subject: MIPS: SMP: Allow suspend and hibernation if CPU hotplug is available

The SMP implementation of suspend and hibernate depends on CPU hotplugging.
In the past we didn't have CPU hotplug so suspend and hibernation were not
possible on SMP systems.

Subject: Revert "PCI: use ACPI _CRS data by default"

This reverts commit 9e9f46c44e487af0a82eb61b624553e2f7118f5b.

Quoting from the commit message:

 "At this point, it seems to solve more problems than it causes, so let's
  try using it by default.  It's an easy revert if it ends up causing
  trouble."

And guess what? The _CRS code causes trouble.

Subject: [ARM] 5560/1: Avoid buffer overrun in case of an invalid IRQ

handle_bad_irq() expects the IRQ number to be valid (used for statistics),
so it cannot be called with an illegal vector. The problem was reported
by a static analysis tool.

The change makes bad_irq_desc redundant, so delete it.

Subject: [ARM] 5565/2: Use PAGE_SIZE and RO_DATA() in link script

Update the link script for ARM to use PAGE_SIZE instead of hard-
coded 4096. Also the old RODATA macro is deprecated
for the RO_DATA(PAGE_SIZE) macro. As a consequence the PAGE_SIZE
was changed from (1UL << PAGE_SHIFT) to (_AC(1,UL) << PAGE_SHIFT)
because the linker does not understand the "UL" suffix to numeric
constants.

Subject: x86: Add sysctl to allow panic on IOCK NMI error

This patch introduces a new sysctl:

    /proc/sys/kernel/panic_on_io_nmi

which defaults to 0 (off).

When enabled, the kernel panics when the kernel receives an NMI
caused by an IO error.

The IO error triggered NMI indicates a serious system
condition, which could result in IO data corruption. Rather
than contiuing, panicing and dumping might be a better choice,
so one can figure out what's causing the IO error.

This could be especially important to companies running IO
intensive applications where corruption must be avoided, e.g. a
bank's databases.

[ SuSE has been shipping it for a while, it was done at the
  request of a large database vendor, for their users. ]

If CONFIG_NO_HZ + CONFIG_SMP, timer added via add_timer() might
be migrated on other cpu.  Use add_timer_on() instead.

Subject: x86, setup: Fix typo "CONFIG_x86_64" in <asm/boot.h>

CONFIG_X86_64 was misspelled (wrong case), which caused the x86-64
kernel to advertise itself as more relocatable than it really is.
This could in theory cause boot failures once bootloaders start
support the new relocation fields.

Subject: sparc: fix tftpboot.img build

Kjetil Oftedal mentioned that piggyback_32 was failing
when building a sparc image.

I tracked this down to the fact that the kernel no longer
provided an absolute symbol named "end".

Commit 86ed40bd6fe511d26bb8f3fa65a84cb65c235366 ("sparc: unify sections.h")
renamed end to _end but failed to update piggyback_32.

Subject: sparc32: Fix makefile not generating required files

The tftpboot build was failing with missing file errors.

It turns out that $(obj)/image wasn't being generated which was causing the a.out conversion to be skipped and hence piggyback to be called with nonexistent files.

Subject: powerpc: Swiotlb breaks pseries

Turning on SWIOTLB selects or enables PPC_NEED_DMA_SYNC_OPS, which means
we get the non empty versions of dma_sync_* in asm/dma-mapping.h

On my pseries machine the dma_ops have no such routines and we die with
a null pointer - this patch gets it booting, is there a more elegant way
to do it?

Subject: powerpc/mpic: Fix mapping of "DCR" based MPIC variants

Commit 31207dab7d2e63795eb15823947bd2f7025b08e2
"Fix incorrect allocation of interrupt rev-map"
introduced a regression crashing on boot on machines using
a "DCR" based MPIC, such as the Cell blades.

The reason is that the irq host data structure is initialized
much later as a result of that patch, causing our calls to
mpic_map() do be done before we have a host setup.

Unfortunately, this breaks _mpic_map_dcr() which uses the
mpic->irqhost to get to the device node.

This fixes it by, instead, passing the device node explicitely
to mpic_map().

Subject: powerpc/warp: Platform fix for i2c change

A change to the i2c subsystem breaks the warp platform code. The patch
is cleaner anyway, the old way was a bit crufty.

For those with keen eyes, the gratuitous change in the string from
PIKA to Warp is just so the logs look a bit nicer. The following two
lines tend to be printed one after another.

  Warp POST OK
  Warp DTM thread running.

Yeah, this will be the third patch to warp.c submitted in this
release....

Cheers,
   Sean

The i2c_client struct changed, breaking the code that looked for the ad7414
chip. Use the new of_find_i2c_device_by_node function added in 2.6.29.

The kernel reserves the I/O address space from 0x0 to 0xfff for legacy
ISA devices. Change the ranges property for the PCI2ISA bridge to match
the kernels behavior, even if the ranges property isn't used for now.

Subject: powerpc/pmac: Fix issues with PowerMac "PowerSurge" SMP

The old PowerSurge SMP (ie, dual or quad 604 machines) code has
numerous issues in modern world.

One is cpu_possible_map is set too late (the device-tree is bogus)
so we fail to allocate the interrupt stacks and crash. Another
problem is the fact the timebase is frozen by the bringup of the
second CPU so the delays in the generic code will hang, we need
to move some of the calling procedure to inside the powermac code.

This makes it boot again for me

Subject: powerpc: Fix output from show_regs

For some reason we've had an explicit KERN_INFO for GPR dumps.  With
recent changes we get output like:

<6>GPR00: 00000000 ef855eb0 ef858000 00000001 000000d0 f1000000 ffbc8000 ffffffff

The KERN_INFO is causing the <6>.  Don't see any reason to keep it
around.

Subject: powerpc: Fix mpic alloc warning

Since we can use kmalloc earlier we are getting the following since the
mpic_alloc() code calls alloc_bootmem().  Move to using kzalloc() to
remove the warning.

Subject: powerpc/mm: Make k(un)map_atomic out of line

Those functions are way too big to be inline, besides, kmap_atomic()
wants to call debug_kmap_atomic() which isn't exported for modules
and causes module link failures.

Subject: powerpc: Map more memory early on 601 processors

The 32-bit kernel relies on some memory being mapped covering
the kernel text,data and bss at least, early during boot before
the full MMU setup is done. On 32-bit "classic" processors, this
is done using BAT registers.

On 601, the size of BATs is limited to 8M and we use 2 of them
for that initial mapping. This can become quite tight when enabling
features like lockdep, so let's use a 3rd one to bump that mapping
from 16M to 24M. We keep the 4th BAT free as it can be useful for
debugging early boot code to map things like serial ports.

Subject: powerpc: Add irqtrace support for 32-bit powerpc

Based on initial work from: Dale Farnsworth <dale@farnsworth.org>

Add the low level irq tracing hooks for 32-bit powerpc needed
to enable full lockdep functionality.

The approach taken to deal with the code in entry_32.S is that
we don't trace all the transitions of MSR:EE when we just turn
it off to peek at TI_FLAGS without races. Only when we are
calling into C code or returning from exceptions with a state
that have changed from what lockdep thinks.

There's a little bugger though: If we take an exception that
keeps interrupts enabled (such as an alignment exception) while
interrupts are enabled, we will call trace_hardirqs_on() on the
way back spurriously. Not a big deal, but to get rid of it would
require remembering in pt_regs that the exception was one of the
type that kept interrupts enabled which we don't know at this
stage. (Well, we could test all cases for regs->trap but that
sucks too much).

Subject: powerpc/rtas: Turn rtas lock into a raw spinlock

RTAS currently uses a normal spinlock. However it can be called from
contexts where this is not necessarily a good idea. For example, it
can be called while syncing timebases, with the core timebase being
frozen. Unfortunately, that will deadlock in case of lock contention
when spinlock debugging is enabled as the spin lock debugging code
will try to use __delay() which ... relies on the timebase being
enabled.

Also RTAS can be used in some low level IRQ handling code path so it
may as well be a raw spinlock for -rt sake.

Subject: powerpc: Use one common impl. of RTAS timebase sync and use raw
 spinlock

Several platforms use their own copy of what is essentially the same code,
using RTAS to synchronize the timebases when bringing up new CPUs. This
moves it all into a single common implementation and additionally
turns the spinlock into a raw spinlock since the former can rely on
the timebase not being frozen when spinlock debugging is enabled, and finally
masks interrupts while the timebase is disabled.

Subject: powerpc/mm: Fix potential access to freed pages when using hugetlbfs

When using 64k page sizes, our PTE pages are split in two halves,
the second half containing the "extension" used to keep track of
individual 4k pages when not using HW 64k pages.

However, our page tables used for hugetlb have a slightly different
format and don't carry that "second half".

Our code that batched PTEs to be invalidated unconditionally reads
the "second half" (to put it into the batch), which means that when
called to invalidate hugetlb PTEs, it will access unrelated memory.

It breaks when CONFIG_DEBUG_PAGEALLOC is enabled.

This fixes it by only accessing the second half when the _PAGE_COMBO
bit is set in the first half, which indicates that we are dealing with
a "combo" page which represents 16x4k subpages. Anything else shouldn't
have this bit set and thus not require loading from the second half.

Subject: asm-generic/vmlinux.lds.h: shuffle INIT_TASK* macro names in
 vmlinux.lds.h

We recently added a INIT_TASK(align) in include/asm-generic/vmlinux.lds.h,
but there is already a macro INIT_TASK in include/linux/init_task.h, which
is quite confusing.  We should switch the macro in the linker script to
INIT_TASK_DATA. (Sorry that I missed this in reviewing the patch).  Since
the macros are new, there is only one user of the INIT_TASK in
vmlinux.lds.h, arch/mn10300/kernel/vmlinux.lds.S.

However, we are currently using INIT_TASK_DATA for laying down an entire
.data.init_task section.  So rename that to INIT_TASK_DATA_SECTION.

I would be worried about changing the meaning of INIT_TASK_DATA, but the
old INIT_TASK_DATA implementation had no users, and in fact if anyone had
tried to use it, it would have failed to compile because it didn't pass
the alignment to the old INIT_TASK.

This reverts commit 95ee14e4379c5e19c0897c872350570402014742.
Mikael Petterson <mikepe@it.uu.se> reported that at least one of his
systems will not boot as a result.  We have ruled out the detection
algorithm malfunctioning, so it is not a matter of producing the
incorrect bitmasks; rather, something in the application of them
fails.

Revert the commit until we can root cause and correct this problem.

-stable team: this means the underlying commit should be rejected.

Subject: KVM: ia64: fix ia64 build due to missing kallsyms_lookup() and double
 export

Fix problem with double export of certain symbols from vsprintf.c
which we do not wish to export from the kvm-intel.ko module.

In addition, we do not have access to kallsyms_lookup() from the
module, so make sure to #undef CONFIG_KALLSYMS

Subject: KVM: s390: Allow stfle instruction in the guest

2.6.31-rc introduced an architecture level set checker based on facility
bits. e.g. if the kernel is compiled to run only on z9, several facility
bits are checked very early and the kernel refuses to boot if a z9 specific
facility is missing.
Until now kvm on s390 did not implement the store facility extended (STFLE)
instruction. A 2.6.31-rc kernel that was compiled for z9 or higher did not
boot in kvm. This patch implements stfle.

This patch should go in before 2.6.31.

Subject: KVM: VMX: Handle vmx instruction vmexits

IF a guest tries to use vmx instructions, inject a #UD to let it know the
instruction is not implemented, rather than crashing.

This prevents guest userspace from crashing the guest kernel.

In commit 7fe29e0faacb650d31b9e9f538203a157bec821d we ignored the
reads to the P6 EVNTSEL MSRs. That fixed crashes on Intel machines.

Ignore the reads to K7 EVNTSEL MSRs as well to fix this on AMD
hosts.

This fixes Kaspersky antivirus crashing Windows guests on AMD hosts.

Subject: intel-iommu: Clean up identity mapping code, remove
 CONFIG_DMAR_GFX_WA

There's no need for the GFX workaround now we have 'iommu=pt' for the
cases where people really care about performance. There's no need to
have a special case for just one type of device.

This also speeds up the iommu=pt path and reduces memory usage by
setting up the si_domain _once_ and then using it for all devices,
rather than giving each device its own private page tables.

It seems that mn10300 made it upstream after Jan Beulich's pci_dac_dma_*
cleanup work and still defines pci_dac_dma_supported(). This API is not
required by the PCI subsystem anymore, so remove it.

This happens to work at the moment but isn't a good idea so fix it the
simple way.

Subject: [IA64] address compiler warnings perfmon.c/salinfo.c

perfmon.c has a dubious cast directly from "int" to "void *". Add
an intermediate cast to "long" to keep gcc happy.

salinfo.c uses "down_trylock()" in a highly creative way (explained
in the comments in the file) ... but it does kick out this warning:

 arch/ia64/kernel/salinfo.c:195: warning: ignoring return value of 'down_trylock'

which people occasionally try to "fix" in ways that do not work. Use some
casts to keep gcc quiet.

The merge of the 32- and 64-bit fixmap headers made a latent

it is possible for FIX_OHCI1394_BASE to overlap the FIX_BTMAP_*

Subject: alpha: fix percpu build breakage

alpha percpu access requires custom SHIFT_PERCPU_PTR() definition for
modules to work around addressing range limitation.  This is done via
generating inline assembly using C preprocessing which forces the
assembler to generate external reference.  This happens behind the
compiler's back and makes the compiler think that static percpu variables
in modules are unused.

This used to be worked around by using __unused attribute for percpu
variables which prevent the compiler from omitting the variable; however,
recent declare/definition attribute unification change broke this as
__used can't be used for declaration.  Also, in the process,
PER_CPU_ATTRIBUTES definition in alpha percpu.h got broken.

This patch adds PER_CPU_DEF_ATTRIBUTES which is only used for definitions
and make alpha use it to add __used for percpu variables in modules.  This
also fixes the PER_CPU_ATTRIBUTES double definition bug.

|
|    page-allocator: clear N_HIGH_MEMORY map before we set it again
|
|    SRAT tables may contains nodes of very small size.  The arch code may
|    decide to not activate such a node.  However, currently the early boot
|    code sets N_HIGH_MEMORY for such nodes.  These nodes therefore seem to be
|    active although these nodes have no present pages.
|
|    For 64bit N_HIGH_MEMORY == N_NORMAL_MEMORY, so that works for 64 bit too

unintentionally and incorrectly clears the cpuset.mems cgroup attribute on
an i386 kvm guest, meaning that cpuset.mems can not be used.

Fix this by only clearing node_states[N_NORMAL_MEMORY] for 64bit only.
and need to do save/restore for that in find_zone_movable_pfn

Subject: sh: fix se7724 ceu names

Use "ceu0" and "ceu1" as CEU names instead of "ceu".
This fixes "memchunk" kernel command line selection
on the solution engine 7724 board.

With this patch applied use "memchunk.ceu0=1m" or
"memchunk.ceu1=1m" on kernel command line to override
physically memory size to one meg for CEU0 or CEU1.

Subject: Fix pci_unmap_addr() et al on i386.

We can run a 32-bit kernel on boxes with an IOMMU, so we need
pci_unmap_addr() etc. to work -- without it, drivers will leak mappings.

To be honest, this whole thing looks like it's more pain than it's
worth; I'm half inclined to remove the no-op #else case altogether.

But this is the minimal fix, which just does the right thing if
CONFIG_DMAR is set.

Subject: perf_counter: Ignore the nmi call frames in the x86-64 backtraces

About every callchains recorded with perf record are filled up
including the internal perfcounter nmi frame:

 perf_callchain
 perf_counter_overflow
 intel_pmu_handle_irq
 perf_counter_nmi_handler
 notifier_call_chain
 atomic_notifier_call_chain
 notify_die
 do_nmi
 nmi

We want ignore this frame as it's not interesting for
instrumentation. To solve this, we simply ignore every frames
from nmi context.

Subject: x86: Fix printk call in print_local_apic()

Instead of this:

[   75.690022] <7>printing local APIC contents on CPU#0/0:
[   75.704406] ... APIC ID:      00000000 (0)
[   75.707905] ... APIC VERSION: 00060015
[   75.722551] ... APIC TASKPRI: 00000000 (00)
[   75.725473] ... APIC PROCPRI: 00000000
[   75.728592] ... APIC LDR: 00000001
[   75.742137] ... APIC SPIV: 000001ff
[   75.744101] ... APIC ISR field:
[   75.746648] 0123456789abcdef0123456789abcdef
[   75.746649] <7>00000000000000000000000000000000

Improve the code to be saner and simpler and just print out
the bitfield in a single line using hexa values - not as a
(rather pointless) binary bitfield.

Partially reused Linus's initial fix for this.

Subject: amd-iommu: handle alias entries correctly in init code

An alias entry in the ACPI table means that the device can send requests to the
IOMMU with both device ids, its own and the alias. This is not handled properly
in the ACPI init code. This patch fixes the issue.

Subject: [ARM] 5579/1: Updated U300 defconfig

This defconfig update selects all the new U300 drivers merged for
2.6.31-rc1 in the merge window and add defaults for the new
config options. It compiles and boots nicely from initramfs on
the U300.

Subject: [ARM] 5581/1: U300 clock updates

This adds a few default locks to the clocks (the clocks were used
before the locks were initialized by code), then renames the clocks
a bit to fit with the latest driver names (some changed during
review). Lastly it moves the initialization of the clock debugfs
entry to module_init() initcall level since the debugfs isn't up
in core_initcall().

From 1bc6f83813441d15a74dfa97966fb68fa1bdec76 Mon Sep 17 00:00:00 2001

Subject: amd-iommu: set evt_buf_size correctly

The setting of this variable got lost during the suspend/resume
implementation.  But keeping this variable zero causes a divide-by-zero
error in the interrupt handler. This patch fixes this.

Subject: x86: fix power-of-2 round_up/round_down macros

These macros had two bugs:
 - the type of the mask was not correctly expanded to the full size of
   the argument being expanded, resulting in possible loss of high bits
   when mixing types.
 - the alignment argument was evaluated twice, despite the macro looking
   like a fancy function (but it really does need to be a macro, since
   it works on arbitrary integer types)

Noticed by Peter Anvin, and with a fix that is a modification of his
suggestion (bug noticed by Yinghai Lu).

Subject: x86: add boundary check for 32bit res before expand e820 resource to
 alignment

fix hang with HIGHMEM_64G and 32bit resource.  According to hpa and
Linus, use (resource_size_t)-1 to fend off big ranges.

Subject: [ARM] 5576/1: Update kb9202_defconfig

The default configuration file for the KwikByte kb9202 board was based on a 2.6.13-rc2 kernel and doesn't produce a bootable kernel. Update the
configuration in order to produce a bootable image.

Subject: parisc: Remove casts from atomic macros

The atomic operations on parisc are defined as macros. The macros
includes casts which disallows the use of some syntax elements and
produces error like this:

net/phonet/pep.c: In function 'pipe_rcv_status':
net/phonet/pep.c:262: error: lvalue required as left operand of assignment

The patch removes this superfluous casts.

Doing an IPI with local interrupts off triggers a warning. We
don't need to be quite so ridiculously paranoid. Also, clean up
a bit of the code a little.

Subject: parisc: fix ldcw inline assembler

There are two reasons to expose the memory *a in the asm:

1) To prevent the compiler from discarding a preceeding write to *a, and
2) to prevent it from caching *a in a register over the asm.

The change has had a few days testing with a SMP build of 2.6.22.19
running on a rp3440.

This patch is about the correctness of the __ldcw() macro itself.
The use of the macro should be confined to small inline functions
to try to limit the effect of clobbering memory on GCC's optimization
of loads and stores.

Subject: parisc: remove obsolete hw_interrupt_type

The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
been kept around for migration reasons.  After more than two years it's
time to remove them finally.

This patch cleans up one of the remaining users.  When all such patches
hit mainline we can remove the defines and typedefs finally.

Impact: cleanup

Convert the last remaining users to struct irq_chip and remove the
define.

Subject: parisc: fix "delay!" timer handling

Rewrote timer_interrupt() to properly handle the "delayed!" case.

If we used floating point math to compute the number of ticks that had
elapsed since the last timer interrupt, it could take up to 12K cycles
(emperical!) to handle the interrupt. Existing code assumed it would
never take more than 8k cycles. We end up programming Interval Timer
to a value less than "current" cycle counter.  Thus have to wait until
Interval Timer "wrapped" and would then get the "delayed!" printk that
I moved below.

Since we don't really know what the upper limit is, I prefer to read
CR16 again after we've programmed it to make sure we won't have to
wait for CR16 to wrap.

Further, the printk was between reading CR16 (cycle couner) and writing CR16
(the interval timer). This would cause us to continue to set the interval
timer to a value that was "behind" the cycle counter. Rinse and repeat.
So no printk's between reading CR16 and setting next interval timer.

Tested on A500 (550 Mhz PA8600).

Kyle, Helge, and other parisc's,
Please test on 32-bit before committing.
I think I have it right but recognize I might not.

TODO: I wanted to use "do_div()" in order to get both remainder
and value back with one division op. That should help with the
latency alot but can be applied seperately from this patch.

thanks,
grant

Subject: parisc: ensure broadcast tlb purge runs single threaded

The TLB flushing functions on hppa, which causes PxTLB broadcasts on the system
bus, needs to be protected by irq-safe spinlocks to avoid irq handlers to deadlock
the kernel. The deadlocks only happened during I/O intensive loads and triggered
pretty seldom, which is why this bug went so long unnoticed.

Subject: parisc: use generic atomic64 on 32-bit

Somewhat redundant since our atomic_t uses hashed-locks on 32-bit
anyway... Maybe we can clean those up to be generic too someday.

This removes the following boot time warning:

Subject: x86: atomic64: The atomic64_t data type should be 8 bytes aligned on
 32-bit too

Locked instructions on two cache lines at once are painful. If
atomic64_t uses two cache lines, my test program is 10x slower.

The chance for that is significant: 4/32 or 12.5%.

Make sure an atomic64_t is 8 bytes aligned.

Subject: x86: atomic64: Move the 32-bit atomic64_t implementation to a .c file

Linus noted that the atomic64_t primitives are all inlines
currently which is crazy because these functions have a large
register footprint anyway.

Move them to a separate file: arch/x86/lib/atomic64_32.c

Also, while at it, rename all uses of 'unsigned long long' to
the much shorter u64.

This makes the appearance of the prototypes a lot nicer - and
it also uncovered a few bugs where (yet unused) API variants
had 'long' as their return type instead of u64.

[ More intrusive changes are not yet done in this patch. ]

Subject: x86: atomic64: Improve atomic64_read()

Linus noticed that the 32-bit version of atomic64_read() was
being overly complex with re-reading the value and doing a
retry loop over that.

Instead we can just rely on cmpxchg8b returning either the new
value or returning the current value.

We can use any 'old' value, which will be faster as it can be
loaded via immediates. Using some value that is not equal to
the real value in memory the instruction gets faster.

This also has the advantage that the CPU could avoid dirtying
the cacheline.

Subject: x86: atomic64: Improve atomic64_add_return()

Linus noted (based on Eric Dumazet's numbers) that we would
probably be better off not trying an atomic_read() in
atomic64_add_return() but intead intentionally let the first
cmpxchg8b fail - to get a cache-friendly 'give me ownership
of this cacheline' transaction. That can then be followed
by the real cmpxchg8b which sets the value local to the CPU.

Subject: x86: atomic64: Reduce size of functions

cmpxchg8b is a huge instruction in terms of register footprint,
we almost never want to inline it, not even within the same
code module.

GCC 4.3 still messes up for two functions, under-judging the
true cost of this instruction - so annotate two key functions
to reduce the bloat:

Subject: x86: Fix fixmap page order for FIX_TEXT_POKE0,1

Masami reported:

> Since the fixmap pages are assigned higher address to lower,
> text_poke() has to use it with inverted order (FIX_TEXT_POKE1
> to FIX_TEXT_POKE0).

I prefer to just invert the order of the fixmap declaration.
It's simpler and more straightforward.

Backward fixmaps seems to be used by both x86 32 and 64.

It's really rare but a nasty bug, because it only hurts when
instructions to patch are crossing a page boundary. If this
happens, the fixmap write accesses will spill on the following
fixmap, which may very well crash the system. And this does not
crash the system, it could leave illegal instructions in place.
Thanks Masami for finding this.

It seems to have crept into the 2.6.30-rc series, so this calls
for a -stable inclusion.

Subject: x86, kvm: Fix section mismatches in kvm.c

The function paravirt_ops_setup() has been refering the
variable no_timer_check, which is a __initdata. Thus generates
the following warning. paravirt_ops_setup() function is called
from kvm_guest_init() which is a __init function. So to fix
this we mark paravirt_ops_setup as __init.

The sections-check output that warned us about this was:

   LD      arch/x86/built-in.o
  WARNING: arch/x86/built-in.o(.text+0x166ce): Section mismatch in
  reference from the function paravirt_ops_setup() to the variable
  .init.data:no_timer_check
  The function paravirt_ops_setup() references
  the variable __initdata no_timer_check.
  This is often because paravirt_ops_setup lacks a __initdata
  annotation or the annotation of no_timer_check is wrong.

Subject: x86: atomic64: Code atomic(64)_read and atomic(64)_set in C not CPP

Occasionally we get bugs where atomic_read or atomic_set are
used on atomic64_t variables or vice versa.  These bugs don't
generate warnings on x86 because atomic_read and atomic_set are
coded as macros rather than C functions, so we don't get any
type-checking on their arguments; similarly for atomic64_read
and atomic64_set in 64-bit kernels.

This converts them to C functions so that the arguments are
type-checked and bugs like this will get caught more easily. It
also converts atomic_cmpxchg and atomic_xchg, and
atomic64_cmpxchg and atomic64_xchg on 64-bit, so we get
type-checking on their arguments too.

Compiling a typical 64-bit x86 config, this generates no new
warnings, and the vmlinux text is 86 bytes smaller.

Subject: MIPS: Define __arch_swab64 for all mips r2 cpus

Some CPUs implement mipsr2, but because they are a super-set of mips64r2 do
not define CONFIG_CPU_MIPS64_R2.  Cavium OCTEON falls into this category.
We would still like to use the optimized implementation, so since we have
already checked for CONFIG_CPU_MIPSR2, checking for CONFIG_64BIT instead of
CONFIG_CPU_MIPS64_R2 is sufficient.

Most of the CMP support was added before, this mostly correct compile
problems but adds a platform specific translation for the interrupt number
based on cpu number.

From: Yong Zhang <yong.zhang@windriver.com>
Date: Wed, 1 Jul 2009 09:35:39 +0800
Subject: MIPS: 64-bit: Fix o32 core dump

If an o32 process generates a core dump on a 64 bit kernel, the core file
will not be correctly recognized. This is because ELF_CORE_COPY_REGS and
ELF_CORE_COPY_TASK_REGS are not correctly defined for o32 and will use
the default register set which would be CONFIG_64BIT in asm/elf.h.

So we'll switch to use the right register defines in this situation by
checking for WANT_COMPAT_REG_H and use the right defines of
ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS.

[Ralf: made ELF_CORE_COPY_TASK_REGS() bullet-proof against funny arguments.]

From: David Daney <ddaney@caviumnetworks.com>
Date: Mon, 29 Jun 2009 17:18:51 -0700
Subject: MIPS: Reorganize Cavium OCTEON PCI support.

Move the cavium PCI files to the arch/mips/pci directory.  Also cleanup
comment formatting and code layout.  Code from pci-common.c, was moved
into other files.

Subject: MIPS: Fix CONFIG_FLATMEM version of pfn_valid()

For systems which do not define PHYS_OFFSET as 0 pfn_valid() may falsely
have returned 0 on most configurations.  Bug introduced by commit
752fbeb2e3555c0d236e992f1195fd7ce30e728d (linux-mips.org) rsp.
6f284a2ce7b8bc49cb8455b1763357897a899abb (kernel.org) titled "[MIPS]
FLATMEM: introduce PHYS_OFFSET."

Subject: x86: atomic64: Export APIs to modules

atomic64_t primitives are used by a handful of drivers,
so export the APIs consistently. These were inlined
before.

Also mark atomic64_32.o a core object, so that the symbols
are available even if not linked to core kernel pieces.

Subject: x86: atomic64: Improve atomic64_xchg()

Remove the read-first logic from atomic64_xchg() and simplify
the loop.

This function was the last user of __atomic64_read() - remove it.

Also, change the 'real_val' assumption from the somewhat quirky
1ULL << 32 value to the (just as arbitrary, but simpler) value
of 0.

Linus noticed that the variable name 'old_val' is
confusingly named in these functions - the correct
naming is 'new_val'.

Subject: x86: atomic64: Inline atomic64_read() again

Now atomic64_read() is light weight (no register pressure and
small icache), we can inline it again.

Also use "=&A" constraint instead of "+A" to avoid warning
about unitialized 'res' variable. (gcc had to force 0 in eax/edx)

We need to give people a little more time to fix the broken drivers.
Re-introduce this, but tied in properly with the 'iommu=pt' support this
time. Change the config option name and make it default to 'no' too.

Add USB host support for port CN27 on the Solution Engine 7724
board. The r8a66597-hcd driver is hooked up as a platform device
and some registers are configured to enable the USB host function.
The hardware driving the USB port is the on-chip USB0 block in
the sh7724 processor configured as USB host controller.

Subject: powerpc/4xx: Have Warp take advantage of GPIO LEDs default-state =
 keep

The GPIO LEDS driver now has a default state of "keep".  Update the Warp DTS
and platform file to take advantage of this new state.  This removes the
hardcoding of the two LEDs on the Warp.

Subject: powerpc/44x: Fix build error with -Werror for Warp platform

With -Werror enabled during the build, the warp.c file fails to build
due to the temp_isr function not containing a return statement.  This
fixes the build error and documents that the function never returns.

Subject: microblaze: use the generic lib/checksum.c

The microblaze checksum code is mostly identical to
the asm-generic+lib version, so use that instead.

Subject: microblaze: convert all simple headers to use asm-generic

All the simple microblaze header files were adapted to use their
asm-generic implementations. These files are more simple and were quite
straightforward to change.

fb.h, vga.h and parport.h previously did not exist, using
the generic version makes it possible to build more drivers
successfully in allyesonfig.

From 3183e06863f49a500fc76427db4d60825a26f81b Mon Sep 17 00:00:00 2001
From: Arnd Bergmann <arnd@arndb.de>
Date: Thu, 18 Jun 2009 19:55:29 +0200
Subject: microblaze: clean up signal handling

When legacy signal handling is disabled, the
arch/microblaze/kernel/signal.c implementation can
be much simpler, as most of it is handled generically
from kernel/signal.c.

This is also a prerequisite for using the generic
asm/unistd.h, which does not provide __NR_sigreturn,
because this macro is referenced by the current signal.c
implementation.

Subject: microblaze: use generic syscalls.h

The prototypes in syscalls.h all make sense for
microblaze, but for some of them, the actual implementation
in sys_microblaze.c needs to be adapted.

Subject: [S390] udelay: disable lockdep to avoid false positives

Our udelay implementation enables interrupts to receive a special timer
interrupt regardless of the context it is called from.
This might lead to false positive lockdep reports. Since lockdep isn't
aware of the fact that only a single interrupt source is enabled it
warns about possible deadlocks that in reality won't happen, like
the one below.
To fix this disable lockdep before enabling interrupts.

Subject: [S390] shutdown actions: save/return rc from init function

We always returned -EINVAL when setting of a shutdown action failed. This was
misleading, if for example the hardware did not support the shutdown action.
Now we save each shutdown action's init return code and return it when the
action is being set.

Performance counters need 64 bit atomic operations.
To keep the patch small we use the simple generic atomic64_t implementation.
The native implementation follows with the next kernel.

Subject: powerpc/pseries: Use pr_devel() in pseries LPAR HPTE routines

pr_debug() can now result in code being generated even when DEBUG
is not defined. That's not really desirable in some places.

In particular, pSeries_lpar_hpte_insert() goes from 185 instructions
to 77 instructions as a result of this patch. Luckily that code
isn't called very often ...

With CONFIG_DYNAMIC_DEBUG=y:

Subject: powerpc: Use pr_devel() in do_dcache_icache_coherency()

pr_debug() can now result in code being generated even when DEBUG
is not defined. That's not really desirable in some places.

With CONFIG_DYNAMIC_DEBUG=y:

Subject: powerpc: Fix spin_event_timeout() to be robust over context switches

Current implementation of spin_event_timeout can be interrupted by an
IRQ or context switch after testing the condition, but before checking
the timeout.  This can cause the loop to report a timeout when the
condition actually became true in the middle.

This patch adds one final check of the condition upon exit of the loop
if the last test of the condition was still false.

Subject: x86: Fix resume from suspend when CONFIG_CC_STACKPROTECTOR

Patch 08687aec71bc9134fe336e561f6did877bacf74fc0a (x86: unify
power/cpu_(32|64).c)  renamed cpu_32.c to cpu.c, but did not update
the special compilation flags for the file for the new name.

This patch fixes the compilation flags, and therefore fixes resume
from suspend on my Acer Aspire One.

[rjw: The regression from 2.6.30 fixed by this patch is tracked as
 http://bugzilla.kernel.org/show_bug.cgi?id=13661]

Commit 5fd29d6ccbc98884569d6f3105aeca70858b3e0f ("printk: clean up
handling of log-levels and newlines") changed printk semantics.  printk
lines with multiple KERN_<level> prefixes are no longer emitted as
before the patch.

<level> is now included in the output on each additional use.

Remove all uses of multiple KERN_<level>s in formats.

Subject: x86: don't clear nodes_states[N_NORMAL_MEMORY] when numa is not
 compiled in

Alex found that specjbb2005 still can not run with hugepages on an
x86-64 machine.  This only happens when numa is not compiled in.

The root cause: node_set_state will not set it back for us in that case,
so don't clear that when numa is not select in config

[ v2: use node_clear_state instead ]

Subject: [ARM] 5594/1: Correct U300 VIC init PM setting

This makes the VIC resume from suspend flagged IRQ:s identical to
the flags indicating all possible interrupts. This is perhaps not
the optimal setting but setting it to 0 makes the system suspend
and never come back again (all IRQ sources masked off).

a lock.

Subject: x86/oprofile: rename kernel parameter for architectural perfmon to
 arch_perfmon

The short name of the achitecture is 'arch_perfmon'. This patch
changes the kernel parameter to use this name.

Subject: perf_counter: Add P6 PMU support

Add basic P6 PMU support. The P6 uses the EVNTSEL0 EN bit to
enable/disable both its counters. We use this for the
global enable/disable, and clear all config bits (except EN)
to disable individual counters.

Actual ia32 hardware doesn't support lfence, so use a locked
op without side-effect to implement a full barrier.

perf stat and perf record seem to function correctly.

[a.p.zijlstra@chello.nl: cleanups and complete the enable/disable code]

Subject: perf_counter: Fix up P6 PMU details

The P6 doesn't seem to support cache ref/hit/miss counts, so
we extend the generic hardware event codes to have 0 and -1
mean the same thing as for the generic cache events.

Furthermore, it turns out the 0 event does not count
(that is, its reported that on PPro it actually does count
something), therefore use a event configuration that's
specified not to count to disable the counters.

Subject: perf_counter: Clean up global vs counter enable

Ingo noticed that both AMD and P6 call
x86_pmu_disable_counter() on *_pmu_enable_counter(). This is
because we rely on the side effect of that call to program
the event config but not touch the EN bit.

We change that for AMD by having enable_all() simply write
the full config in, and for P6 by explicitly coding it.

Subject: Fix congestion_wait() sync/async vs read/write confusion

Commit 1faa16d22877f4839bd433547d770c676d1d964c accidentally broke
the bdi congestion wait queue logic, causing us to wait on congestion
for WRITE (== 1) when we really wanted BLK_RW_ASYNC (== 0) instead.

Subject: x86/pci: insert ioapic resource before assigning unassigned resources

Stephen reported that his DL585 G2 needed noapic after 2.6.22 (?)

Dann bisected it down to:
  commit 30a18d6c3f1e774de656ebd8ff219d53e2ba4029
  Date:   Tue Feb 19 03:21:20 2008 -0800

      x86: multi pci root bus with different io resource range, on
      64-bit

It turns out that:
  1. that AMD-based systems have two HT chains.
  2. BIOS doesn't allocate resources for BAR 6 of devices under 8132 etc
  3. that multi-peer-root patch will try to split root resources to peer
     root resources according to PCI conf of NB
  4. PCI core assigns unassigned resources, but they overlap with BARs
     that are used by ioapic addr of io4 and 8132.

The reason: at that point ioapic address are not inserted yet.  Solution
is to insert ioapic resources into the tree a bit earlier.

From c99e6efe1ba04561e7d93a81f0be07e37427e835 Mon Sep 17 00:00:00 2001
From: Peter Zijlstra <a.p.zijlstra@chello.nl>

Subject: sched: INIT_PREEMPT_COUNT

Pull the initial preempt_count value into a single
definition site.

Maintainers for: alpha, ia64 and m68k, please have a look,
your arch code is funny.

The header magic is a bit odd, but similar to the KERNEL_DS
one, CPP waits with expanding these macros until the
INIT_THREAD_INFO macro itself is expanded, which is in
arch/*/kernel/init_task.c where we've already included
sched.h so we're good.

Subject: x86: Remove spurious printk level from segfault message

Since commit 5fd29d6c ("printk: clean up handling of log-levels
and newlines"), the kernel logs segfaults like:

    <6>gnome-power-man[24509]: segfault at 20 ip 00007f9d4950465a sp 00007fffbb50fc70 error 4 in libgobject-2.0.so.0.2103.0[7f9d494f7000+45000]

with the extra "<6>" being KERN_INFO.  This happens because the
printk in show_signal_msg() started with KERN_CONT and then
used "%s" to pass in the real level; and KERN_CONT is no longer
an empty string, and printk only pays attention to the level at
the very beginning of the format string.

Therefore, remove the KERN_CONT from this printk, since it is
now actively causing problems (and never really made any
sense).

Subject: headers: smp_lock.h redux

* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)

Subject: perf_counter, x86: Extend perf_counter Pentium M support

I've attached a patch to remove the Pentium M special casing of
EMON and as noticed at least with my Pentium M the hardware PMU
now works:

 Performance counter stats for '/bin/ls /var/tmp':

       1.809988  task-clock-msecs         #      0.125 CPUs
              1  context-switches         #      0.001 M/sec
              0  CPU-migrations           #	 0.000 M/sec
            224  page-faults              #	 0.124 M/sec
        1425648  cycles                   #    787.656 M/sec
         912755  instructions             #	 0.640 IPC

Vince suggested that this code was trying to address erratum
Y17 in Pentium-M's:

  http://download.intel.com/support/processors/mobile/pm/sb/25266532.pdf

But that erratum (related to IA32_MISC_ENABLES.7) does not
affect perfcounters as we dont use this toggle to disable RDPMC
and WRMSR/RDMSR access to performance counters. We keep cr4's
bit 8 (X86_CR4_PCE) clear so unprivileged RDPMC access is not
allowed anyway.

Subject: x86: Fix false positive section mismatch in es7000_32.c

The variable apic_es7000_cluster references the function __cpuinit
wakeup_secondary_cpu_via_mip() from a noninit section. So we've been
warned by the following warning. To avoid possible collision between
init/noninit, its best to mark the variable as __refdata.

We were warned by the following warning:

Subject: x86, apic: Fix false positive section mismatch in numaq_32.c

The variable apic_numaq placed in noninit section references the
function wakeup_secondary_cpu_via_nmi(), which is in __cpuinit
section. Thus causes a section mismatch warning. To avoid such
mismatch we mark apic_numaq as __refdata.

We were warned by the following warning:

On booke processors, gdb is seeing spurious SIGTRAPs when setting a
watchpoint.

user_disable_single_step() simply quits when the DAC is non-zero.  It should
be clearing the DBCR0_IC and DBCR0_BT bits from the dbcr0 register and
TIF_SINGLESTEP from the thread flag.

There are no CONFIG_{BLK,CHR}_DEV_FLASH Kconfig options, and there is no

Seems to be dead code that stretches way back to the start of the Blackfin

Subject: Blackfin: work around anomaly 05000281

Add missing anomaly workaround for anomaly 05000281 - we can't return to
instructions which cause hardware errors otherwise we trigger the error
again which means we go into an infinite loop of handling, returning, and
retriggering.  This work around confuses gdb when the error occurs as the
PC will seemed to have moved, so a better long term fix will need to be
figured out, but for now this is better than an infinite crash loop.

Subject: Blackfin: fix silent crash when no uClinux MTD filesystem exists

Since we need to relocate the attached filesystem with the uClinux MTD map
(to handle some anomalies), we need to know its real filesize.  If we boot
a kernel without a filesystem actually attached, we end up blindly reading
and copying garbage (since there is no magic value to detect validity).
Often times this results in an early crash and no output.  So add a few
basic sanity checks before operating on things to catch the majority of
cases.

Subject: Blackfin: fix miscompilation in lshrdi3

The code used in the Blackfin lshrdi3 utilizes gcc constructs.  However,
the structures declared don't line up with the code gcc generates, so
under certain optimizations, we get bad code and things crap out in fun
random ways.  So rather than trying to maintain different gcc definitions
ourselves, just use the ones available in gcclib.h.

Subject: Blackfin: handle BF561 Core B memory regions better when SMP=n

Rather than assume Core B is always run with caches turned on, let people
load into any of the on-chip memory regions.  It is their business how the
SRAM/Cache regions are utilized, so don't prevent them from being able to
load into them.

Subject: Blackfin: fix early_dma_memcpy() handling of busy channels

The early logic to locate a free DMA channel and then set it up was broken
in a few ways that only manifested itself when we needed to set up more
than 2 on chip SRAM regions (most board defaults setup 1 or 2).  First, we
checked the wrong status register (the destination gets updated, not the
source) and second, we did the ssync before rather than after resetting a
DMA config register.

Subject: Blackfin: update handling of anomaly 364 (wrong rev id in BF527-0.1)

This anomaly only applies to the BF527-0.1, not the BF526-0.1, and not any
other revision of the BF527.  So make sure we don't go returning 0xffff
for other cases.

Subject: Blackfin: drop per-cpu loops_per_jiffy tracking

On Blackfin SMP, a per-cpu loops_per_jiffy is pointless since both cores
always run at the same CCLK.  In addition, the current implementation has
flaws since the main consumer for loops_per_jiffy (asm/delay.h) uses the
global kernel loops_per_jiffy and not the per_cpu one.  So punt all of the
per-cpu handling and go back to the global shared one.

Subject: arch/blackfin: Add kmalloc NULL tests

Check that the result of kmalloc is not NULL before passing it to other
functions.

In the first two cases, the new code returns -ENOMEM, which seems
compatible with what is done for similar functions for other architectures.

In the last two cases, the new code fails silently, ie just returns,
because the function has void return type.

The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
expression *x;
identifier f;
constant char *C;
@@

x = \(kmalloc\|kcalloc\|kzalloc\)(...);

    when != (x || ...)

Subject: Fix ia64 compilation IS_ERR and PTE_ERR errors.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When building ia64 kernel with CONFIG_XEN_SYS_HYPERVISOR, compiler reports
errors:

drivers/xen/sys-hypervisor.c: In function ‘uuid_show’:
drivers/xen/sys-hypervisor.c:125: error: implicit declaration of function ‘IS_ERR’
drivers/xen/sys-hypervisor.c:126: error: implicit declaration of function ‘PTR_ERR’

This patch fixes the errors.

 arch/ia64/include/asm/fpu.h"

asm/fpu.h uses the __IA64_UL macro which is declared in asm/types.h, so
this include is really required. Without it, GNU libc fails to build.

This reverts commit 2678c07b07ac2076675e5d57653bdf02e9af1950.

Subject: vmlinux.lds.h: restructure BSS linker script macros

The BSS section macros in vmlinux.lds.h currently place the .sbss
input section outside the bounds of [__bss_start, __bss_end].  On all
architectures except for microblaze that handle both .sbss and
__bss_start/__bss_end, this is wrong: the .sbss input section is
within the range [__bss_start, __bss_end].  Relatedly, the example
code at the top of the file actually has __bss_start/__bss_end defined
twice; I believe the right fix here is to define them in the
BSS_SECTION macro but not in the BSS macro.

Another problem with the current macros is that several
architectures have an ALIGN(4) or some other small number just before
__bss_stop in their linker scripts.  The BSS_SECTION macro currently
hardcodes this to 4; while it should really be an argument.  It also
ignores its sbss_align argument; fix that.

mn10300 is the only user at present of any of the macros touched by
this patch.  It looks like mn10300 actually was incorrectly converted
to use the new BSS() macro (the alignment of 4 prior to conversion was
a __bss_stop alignment, but the argument to the BSS macro is a start
alignment).  So fix this as well.

I'd like acks from Sam and David on this one.  Also CCing Paul, since
he has a patch from me which will need to be updated to use
BSS_SECTION(0, PAGE_SIZE, 4) once this gets merged.

This issue is caused by using gpio pin without request. Add gpio_request()
into zylonite. To simplify the code, error checking is omitted since this
is being performed early.

AMI BIOS with low memory corruption was found on Intel DG45ID

not having this bug.

Fix i2c_board_info definitions - we were defining the 'type' field

The Blackfin serial headers were inverting the CTS value leading to wrong
handling of the CTS line which broke CTS/RTS handling completely.

Subject: x86: Fix movq immediate operand constraints in uaccess_64.h

arch/x86/include/asm/uaccess_64.h uses wrong asm operand constraint
("ir") for movq insn. Since movq sign-extends its immediate operand,
"er" constraint should be used instead.

Attached patch changes all uses of __put_user_asm in uaccess_64.h to use
"er" when "q" insn suffix is involved.

Patch was compile tested on x86_64 with defconfig.

Subject: x86, amd: Don't probe for extended APIC ID if APICs are disabled

If we've logically disabled apics, don't probe the PCI space for the
AMD extended APIC ID.

[ Impact: prevent boot crash under Xen. ]

Subject: dmaengine: at_hdmac: new driver for the Atmel AHB DMA Controller

This AHB DMA Controller (aka HDMA or DMAC on AT91 systems) is availlable on
at91sam9rl chip. It will be used on other products in the future.

This first release covers only the memory-to-memory tranfer type. This is the
only tranfer type supported by this chip.  On other products, it will be used
also for peripheral DMA transfer (slave API support to come).

I used dmatest client without problem in different configurations to test it.

Full documentation for this controller can be found in the SAM9RL datasheet:
http://www.atmel.com/dyn/products/product_card.asp?part_id=4243

Subject: dmaengine: at_hdmac: add DMA slave transfers

This patch for at_hdmac adds the slave transfers capability to the Atmel DMA
controller available on some AT91 SOCs. This allow peripheral to memory and
memory to peripheral transfers with hardware handshaking.

Slave structure for controller specific information is passed through channel
private data. This at_dma_slave structure is defined in at_hdmac.h header file
and relative hardware definition are moved to this file from at_hdmac_regs.h.
Doing this we allow the channel configuration from platform definition code.

This work is intensively based on dw_dmac and several slave implementations.

Subject: [ARM] 5611/1: ep93xx: update ts72xx nor flash support

Update the NOR flash support for TS-7200.

The TS-7200 models all have 16-bit NOR flash.  Update the platform
init to support this.

Remove the private TS72XX_NOR_* defines and use the common ep93xx
defines for the external chip select physical base address instead.

Move the NOR flash registration into a static __init function.  When
the NAND flash support is updated this function will also be used
to register the NAND flash for the TS-7250 and TS-7260.

Subject: x86: geode: Mark mfgpt irq IRQF_TIMER to prevent resume failure

Timer interrupts are excluded from being disabled during suspend. The
clock events code manages the disabling of clock events on its own
because the timer interrupt needs to be functional before the resume
code reenables the device interrupts.

The mfgpt timer request its interrupt without setting the IRQF_TIMER
flag so suspend_device_irqs() disables it as well which results in a
fatal resume failure.

Adding IRQF_TIMER to the interupt flags when requesting the mrgpt
timer interrupt solves the problem.

Subject: [S390] hibernation: fix lowcore handling

Our swsusp_arch_suspend() backend implementation disables prefixing
by setting the contents of the prefix register to 0.
However afterwards common code functions are called which might
access percpu data structures.
Since the lowcore contains e.g. the percpu base pointer this isn't
a good idea. So fix this by copying the hibernating cpu's lowcore to
absolute address zero.

Subject: [S390] hibernation: fix register corruption on machine checks

swsusp_arch_suspend() actually saves all cpu register contents on
hibernation.
Machine checks must be disabled since swsusp_arch_suspend() stores
register contents to their lowcore save areas. That's the same
place where register contents on machine checks would be saved.
To avoid register corruption disable machine checks.
We must also disable machine checks in the new psw mask for
program checks, since swsusp_arch_suspend() may generate program
checks.

vdso per cpu area allocation in smp_prepare_cpus() happens with GFP_KERNEL

Fix this by moving the allocation out of the irqs disabled section.

Subject: [S390] vdso: clock_gettime of CLOCK_THREAD_CPUTIME_ID with noexec=on

The combination of noexec=on and a clock_gettime call with clock id
CLOCK_THREAD_CPUTIME_ID is broken. The vdso code switches to the
access register mode to get access to the per-cpu data structure to
execute the magic ectg instruction. After the ectg instruction the
code always switches back to the primary mode but for noexec=on the
correct mode is the secondary mode. The effect of the bug is that the
user space program looses the access to all mappings without PROT_EXEC,
e.g. the stack. The problem is fixed by restoring the mode that has
been active before the switch to the access register mode.

Subject: OMAP3 SDRC: add support for 2 SDRAM chip selects

Some OMAP3 boards (Beagle Cx, Overo, RX51, Pandora) have 2
SDRAM parts connected to the SDRC.

This patch adds the following:
- add a new argument of type omap_sdrc_params struct*
to omap2_init_common_hw and omap2_sdrc_init for the 2nd CS params
- adapted the OMAP boards files to the new prototype of
omap2_init_common_hw
- add the SDRC 2nd CS registers offsets defines
- adapt the sram sleep code to configure the SDRC for the 2nd CS

Note: If the 2nd param to omap2_init_common_hw is NULL, then the
parameters are not programmed into the SDRC CS1 registers

Tested on 3430 SDP and Beagleboard rev C2 and B5, with
suspend/resume and frequency changes (cpufreq).

Subject: OMAP3: Setup MUX settings for SDRC CKE signals

This patches ensures the MUX settings are correct for the SDRC
CKE signals to SDRAM. This allows the self-refresh to work when
2 chip-selects are in use.

A warning is thrown away in case the initial muxing is incorrect,
in order to track faulty or old-dated bootloaders.
Note: The CONFIG_OMAP_MUX and CONFIG_OMAP_MUX_WARNINGS options
must be enabled for the mux code to have effect.

Subject: OMAP2/3 SDRC: don't set SDRC_POWER.PWDENA on boot

Stop setting SDRC_POWER.PWDENA on boot.  There is a nasty erratum
(34xx erratum 1.150) that can cause memory corruption if PWDENA is
enabled.

Based originally on a patch from Samu P. Onkalo <samu.p.onkalo@nokia.com>.

Tested on BeagleBoard rev C2.

Subject: OMAP3 SDRC: Fix freeze when scaling CORE dpll to < 83Mhz

This patch fixes a bug in the CORE dpll scaling sequence which was
errouneously clearing some bits in the SDRC DLLA CTRL register and
hence causing a freeze.  The issue was observed only on platforms
which scale CORE dpll to < 83Mhz and hence program the DLL in fixed
delay mode.

Issue reported by Limei Wang <E12499@motorola.com>, with debugging
assistance from Richard Woodruff <r-woodruff2@ti.com> and Girish
Ghongdemath <girishsg@ti.com>.

Subject: OMAP2/3 clock: split, rename omap2_wait_clock_ready()

Some OMAP2/3 hardware modules have CM_IDLEST attributes that are not
handled by the current omap2_wait_clock_ready() code.  In preparation
for patches that fix the unusual devices, rename the function
omap2_wait_clock_ready() to omap2_wait_module_ready() and split it
into three parts:

1. A clkops-specific companion clock return function (by default,
   omap2_clk_dflt_find_companion())

2. A clkops-specific CM_IDLEST register address and bit shift return
   function (by default, omap2_clk_dflt_find_idlest())

3. Code to wait for the CM to indicate that the module is ready
   (omap2_cm_wait_idlest())

Clocks can now specify their own custom find_companion() and find_idlest()
functions; used in subsequent patches.

Subject: OMAP3 clock: correct module IDLEST bits: SSI; DSS; USBHOST; HSOTGUSB

Fix two bugs in the OMAP3 clock tree pertaining to the SSI, DSS,
USBHOST, and HSOTGUSB devices.  These devices are both interconnect
initiators and targets.  Without this patch, clk_enable()s on clocks for
these modules can be very high latency (potentially up to ~200
milliseconds) and message such as the following are generated:

    Clock usbhost_48m_fck didn't enable in 100000 tries

Two bugs are fixed by this patch.  First, OMAP hardware only supports
target CM_IDLEST register bits on ES2+ chips and beyond.  ES1 chips
should not wait for these clocks to enable.  So, split the appropriate
clocks into ES1 and ES2+ variants, so that kernels running on ES1
devices won't try to wait.

Second, the current heuristic in omap2_clk_dflt_find_idlest() will
fail for these clocks.  It assumes that the CM_IDLEST bit to wait upon
is the same as the CM_*CLKEN bit, which is false[1].  Fix by
implementing custom clkops .find_idlest function pointers for the
appropriate clocks that return the correct slave IDLEST bit shift.

This was originally fixed in the linux-omap kernel during 2.6.29 in a
slightly different manner[2][3].

In the medium-term future, all of the module IDLEST code will
eventually be moved to the omap_hwmod code.

Problem reported by Jarkko Nikula <jhnikula@gmail.com>:

If r7 is zero at kernel boot, or does not point to a valid DTB, then
we fall back to a DTB (assumed to be) linked statically in the kernel, instead
of blindly copying bogus cruft into the kernel DTB memory region

Subject: microblaze: Fix put_user macro for 64bits arguments

For 64bits arguments gcc caused that put_user macro
works with wrong value because of optimalization.
Adding volatile caused that gcc not optimized it.

It is possible to use (as Blackfin do) two put_user
macros with 32bits arguments but there is one more
instruction which is due to duplication zero return
value which is called put_user_asm macro.

Subject: microblaze: Support unaligned address for put/get_user macros

This patch add support for cases where load/store instruction
in put/get_user macro gets unaligned pointer to data and this
address is not valid. I prevent all cases which can failed.
I had to disable first stage of unaligned handler which is used
only for noMMU kernel and the whole work is done when interrupt
is enabled.
You have enable HW support for detect unaligned access in Microblaze.

This patch fixed three LTP tests:
getpeername01, getsockname01, socketpair01

Subject: microblaze: Get module loading working

New reloc type R_MICROBLAZE_32_PCREL_LO requires a null handler (no work to do).

Remove legacy hack for broken linker pre gcc-4.1.1, that required us to extract
an offset from the code, add it to the addend, then rewrite the instruction.

Fixup the invalid reloc type error output.

Boot tested with the xilinx_emaclite ethernet driver.

Subject: microblaze: Makefile cleanup

Reviewed the Makefile on request by Michal and this is the resulting changes.

o Use ':=' for assignmnet so we do not re-evaluate for each use
o Use $(shell echo xxx) to remove ""
o Replaced CFLAGS_KERNEL with KBUILD_CFLAGS
  The settings are equally relevant for modules and the linked kernel
o Dropped LDFLAGS_BLOB - it is no longer used
o Refactored assignmnets to libs-y and core-y
o Use MMU for the MMU specific extension. "MMUEXT" was hurting my eyes
  and I did not wanted it spread to m68k

Subject: avr32/lib: fix unaligned memcpy()

memcpy(p, unaligned, 4..) returns (p + num_of_unaligned_by_copied)
instead of p because p is not preserved in the unaligned case.

Noticed by Herbert Xu's superior parameter recycling coding technique
which let the md4 self-test fail on avr32.

Subject: favr32: improve touchscreen response

The ezLCD+101 board (to which an favr-32 is fitted) has a long,
unshielded, nasty lead between the touch panel and the ads7843 touch
controller.  In order to get satisfactory response then, we need to
employ every noise-reduction trick in the driver's arsenal.  After
extensive fiddling I've found some good settings:

1) We keep vref on all the time to dramatically reduce settling times
(at the cost of a tiny increase in power consumption).

2) Despite 1 the settling time is still non-zero.  500uS is plenty of
time for the signals to settle

3) Despite 1 and 2 there's still a little bit of noise around.  By
setting a pen recheck delay we make the panel feel less touchy and
twitchy.

Someone with more time and patience myself might be able to tune this
numbers further but these settings are now perfectly acceptable for
normal use.

Tested on ezLCD+101 though should only improve response on other ezLCD+/
favr-32 boards too.

Subject: mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()

mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()

Upcoming paches to support the new 64-bit "BookE" powerpc architecture
will need to have the virtual address corresponding to PTE page when
freeing it, due to the way the HW table walker works.

Basically, the TLB can be loaded with "large" pages that cover the whole
virtual space (well, sort-of, half of it actually) represented by a PTE
page, and which contain an "indirect" bit indicating that this TLB entry
RPN points to an array of PTEs from which the TLB can then create direct
entries. Thus, in order to invalidate those when PTE pages are deleted,
we need the virtual address to pass to tlbilx or tlbivax instructions.

The old trick of sticking it somewhere in the PTE page struct page sucks
too much, the address is almost readily available in all call sites and
almost everybody implemets these as macros, so we may as well add the
argument everywhere. I added it to the pmd and pud variants for consistency.

Subject: x86: fix section mismatch for i386 init code

Startup code for i386 in arch/x86/kernel/head_32.S is using the
reference variable initial_code that is located in the .cpuinit.data
section. If CONFIG_HOTPLUG_CPU is enabled, startup code is not in an
init section and can be called later too. In this case the reference
initial_code must be kept too. This patch fixes this. See below for
the section mismatch warning.

 WARNING: vmlinux.o(.cpuinit.data+0x0): Section mismatch in reference
 from the variable initial_code to the function
 .init.text:i386_start_kernel()
 The variable __cpuinitdata initial_code references
 a function __init i386_start_kernel().
 If i386_start_kernel is only used by initial_code then
 annotate i386_start_kernel with a matching annotation.

Subject: sparc64: Sign extend length arg to truncate syscalls when compat.

The first thing sys_truncate() and sys_ftruncate() do is sign extend
the unsigned length arg to a signed type.

Thanks to Benjamin Herrenschmidt for the tip.

Subject: S3C24XX: GPIO: Fix pin range check in s3c_gpiolib_getchip

In the s3c_gpiolib_getchip implementation for s3c24xx the check whether a pin is
in the gpio banks range is reversed. Thus the function returns NULL for valid
pins and the gpio chip if its not valid.

As a result gpio states are not saved/restored properly during suspend/resume.

This is critical for cpufreq support, without it attempts to scale

Subject: powerpc/mm: Fix SMP issue with MMU context handling code

In switch_mmu_context() if we call steal_context_smp() to get a context
to use we shouldn't fall through and than call steal_context_up().  Doing
so can be problematic in that the 'mm' that steal_context_up() ends up
using will not get marked dirty in the stale_map[] for other CPUs that
might have used that mm.  Thus we could end up with stale TLB entries in
the other CPUs that can cause all kinda of havoc.

Subject: powerpc/85xx: Fix ethernet link detection on MPC8569E-MDS boards

Linux isn't able to detect link changes on ethernet ports that were
used by U-Boot. This is because U-Boot wrongly clears interrupt
polarity bit (INTPOL, 0x400) in the extended status register (EXT_SR,
0x1b) of Marvell PHYs.

There is no easy way for PHY drivers to know IRQ line polarity (we
could extract it from the device tree and pass it to phydevs, but
that'll be quite a lot of work), so for now just reset the PHYs to
their default states.

Subject: powerpc/85xx: Don't scan for TBI PHY addresses on MPC8569E-MDS boards

Sometimes (e.g. when there are no UEMs attached to a board)
fsl_pq_mdio_find_free() fails to find a spare address for a TBI PHY,
this is because get_phy_id() returns bogus 0x0000ffff values
(0xffffffff is expected), and therefore mdio bus probing fails with
the following message:

  fsl-pq_mdio: probe of e0082120.mdio failed with error -16

And obviously ethernet doesn't work after this.

This patch solves the problem by adding tbi-phy node into mdio node,
so that we won't scan for spare addresses, we'll just use a fixed one.

From 2e04ef76916d1e29a077ea9d0f2003c8fd86724d Mon Sep 17 00:00:00 2001
From: Rusty Russell <rusty@rustcorp.com.au>
Date: Thu, 30 Jul 2009 16:03:45 -0600
Subject: lguest: fix comment style

I don't really notice it (except to begrudge the extra vertical
space), but Ingo does.  And he pointed out that one excuse of lguest
is as a teaching tool, it should set a good example.

Subject: lguest: update commentry

Every so often, after code shuffles, I need to go through and unbitrot
the Lguest Journey (see drivers/lguest/README).  Since we now use RCU in
a simple form in one place I took the opportunity to expand that explanation.

ensuring that tcmp < tcnt.

Subject: x86, pat: Fix set_memory_wc related corruption

Changeset 3869c4aa18835c8c61b44bd0f3ace36e9d3b5bd0
that went in after 2.6.30-rc1 was a seemingly small change to _set_memory_wc()
to make it complaint with SDM requirements. But, introduced a nasty bug, which
can result in crash and/or strange corruptions when set_memory_wc is used.
One such crash reported here
http://lkml.org/lkml/2009/7/30/94

Actually, that changeset introduced two bugs.
* change_page_attr_set() takes &addr as first argument and can the addr value
  might have changed on return, even for single page change_page_attr_set()
  call. That will make the second change_page_attr_set() in this routine
  operate on unrelated addr, that can eventually cause strange corruptions
  and bad page state crash.
* The second change_page_attr_set() call, before setting _PAGE_CACHE_WC, should
  clear the earlier _PAGE_CACHE_UC_MINUS, as otherwise cache attribute will not
  be WC (will be UC instead).

The patch below fixes both these problems. Sending a single patch to fix both
the problems, as the change is to the same line of code. The change to have a
addr_copy is not very clean. But, it is simpler than making more changes
through various routines in pageattr.c.

A huge thanks to Jerome for reporting this problem and providing a simple test
case that helped us root cause the problem.

They tend to get not updated when files are moved around or copied and

as per Shinya's suggestion, add a copyright header to extable.c.

Subject: MIPS: Avoid clobbering struct pt_regs in kthreads

The resume() implementation octeon_switch.S examines the saved cp0_status
register.  We were clobbering the entire pt_regs structure in kernel
threads leading to random crashes.

When switching away from a kernel thread, the saved cp0_status is examined
and if bit 30 is set it is cleared and the CP2 state saved into the pt_regs
structure.  Since the kernel thread stack overlaid the pt_regs structure
this resulted in a corrupt stack.  When the kthread with the corrupt stack
was resumed, it could crash if it used any of the data in the stack that was
clobbered.

We fix it by moving the kernel thread stack down so it doesn't overlay
pt_regs.

Subject: MIPS: Fix loading of modules with unresolved weak symbols

Loading of modules with unresolved weak symbols fails on MIPS
since '88173507e4fc1e7ecd111b0565e8cba0cb7dae6d'.

Modules: handle symbols that have a zero value

The module subsystem cannot handle symbols that are zero.  If symbols
are present that have a zero value then the module resolver prints out a
message that these symbols are unresolved.

We have to use IS_ERR_VALUE() to check that a symbol has been resolved
or not.

Trying to build MSP4200 VoIP defconfig also fails on msp_irq_slp.c with a

Passed that, we will also miss a comma when calling

Subject: MIPS: Simplify and correct interrupt handling for MSP4200

The current interrupt handling code for the MSP4200 always masks an
interrupt before acknowledging it.  This is not required, as that will be
handled by the level interrupt handler.  This change simplifies the MSP4200
code to remove the masking in the ack routine, and makes sure that the
minimum required operation is performed for masking and acking, rather
than always both masking and acking the interrupt.

Subject: MIPS: MTX-1: Request button GPIO before setting its direction

This patch fixes the following warning at boot time:
WARNING: at drivers/gpio/gpiolib.c:83 0x8021d5e0()
autorequest GPIO-207
Modules linked in:
Call Trace:[<8011e0ec>] 0x8011e0ec
[<80110a28>] 0x80110a28
[<80110a28>] 0x80110a28
[..snip..]

The current code does not request the GPIO and attempts
to set its direction, which is a violation of the GPIO API.
This patch also unhardcode the GPIO we request and use
the one we defined in the button driver.

In mm/slab.c the function do_ccupdate_local requires that interrupts be
disabled.  If they are not, we panic with CONFIG_DEBUG_SLAB.

So we disable interrupts while processing IPIs.  Also these are not shared
irqs, so get rid of the IRQF_SHARED flag.

Subject: x86: Fix CPA memtype reserving in the set_pages_array*() cases

The code was incorrectly reserving memtypes using the page
virtual address instead of the physical address. Furthermore,
the code was not ignoring highmem pages as it ought to.

( upstream does not pass in highmem pages yet - but upcoming
  graphics code will do it and there's no reason to not handle
  this properly in the CPA APIs.)

Fixes: http://bugzilla.kernel.org/show_bug.cgi?id=13884

Subject: x86: Add quirk to make Apple MacBook5,2 use reboot=pci

The latest Apple MacBook (MacBook5,2) doesn't reboot successfully
under Linux; neither the EFI reboot method nor the default method
using the keyboard controller works (the system just hangs and doesn't
reset).  However, the method using the "PCI reset register" at 0xcf9
does work.

This adds a quirk to detect this machine via DMI and force the
reboot_type to BOOT_CF9.  With this it reboots successfully without
requiring a command-line option.  Note that the EFI code forces
reboot_type to BOOT_EFI when the machine is booted via EFI, but this
overrides that since the core_initcall runs after the EFI
initialization code.

This happens because the 64-bit version of efi_ioremap calls
init_memory_mapping for all addresses, regardless of whether they are
RAM or MMIO.  The EFI tables on this machine ask for runtime access to
some MMIO regions:

[    0.000000] EFI: mem195: type=11, attr=0x8000000000000000, range=[0x0000000093400000-0x0000000093401000) (0MB)

[    0.000000] EFI: mem198: type=11, attr=0x8000000000000000, range=[0x00000000ffc80000-0x00000000ffca4000) (0MB)

[    0.000000] EFI: mem200: type=11, attr=0x8000000000000000, range=[0x00000000ffcb4000-0x00000000ffffc000) (3MB)
[    0.000000] EFI: mem201: type=11, attr=0x8000000000000000, range=[0x00000000ffffc000-0x0000000100000000) (0MB)

This arranges to pass the EFI memory type through to efi_ioremap, and
makes efi_ioremap use ioremap rather than init_memory_mapping if the
type is EFI_MEMORY_MAPPED_IO.  With this, the above warning goes away.

Subject: x86: fix assembly constraints in native_save_fl()

From Gabe Black in bugzilla 13888:

native_save_fl is implemented as follows:

  11static inline unsigned long native_save_fl(void)
  12{
  13        unsigned long flags;
  14
  15        asm volatile("# __raw_save_flags\n\t"
  16                     "pushf ; pop %0"
  17                     : "=g" (flags)
  18                     : /* no input */
  19                     : "memory");
  20
  21        return flags;
  22}

If gcc chooses to put flags on the stack, for instance because this is
inlined into a larger function with more register pressure, the offset
of the flags variable from the stack pointer will change when the
pushf is performed. gcc doesn't attempt to understand that fact, and
address used for pop will still be the same. It will write to
somewhere near flags on the stack but not actually into it and
overwrite some other value.

I saw this happen in the ide_device_add_all function when running in a
simulator I work on. I'm assuming that some quirk of how the simulated
hardware is set up caused the code path this is on to be executed when
it normally wouldn't.

A simple fix might be to change "=g" to "=r".

Subject: x86: Don't use current_cpu_data in x2apic phys_pkg_id

One system has socket 1 come up as BSP.

kexeced kernel reports BSP as:

It doesn't have correct physical processor id and will get an

it turns out: we can not use current_cpu_data in phys_pgd_id
for x2apic.

identify_boot_cpu() is called by check_bugs() before
smp_prepare_cpus() and till smp_prepare_cpus() current_cpu_data
for bsp is assigned with boot_cpu_data.

Just make phys_pkg_id for x2apic is aligned to xapic.

With VMALLOC_END included in the calculation of MAXMEM (as of

Subject: x86, UV: Complete IRQ interrupt migration in arch_enable_uv_irq()

In uv_setup_irq(), the call to create_irq() initially assigns
IRQ vectors to cpu 0. The subsequent call to
assign_irq_vector() in arch_enable_uv_irq() migrates the IRQ to
another cpu and frees the cpu 0 vector - at least it will be
freed as soon as the "IRQ move" completes.

arch_enable_uv_irq() needs to send a cleanup IPI to complete
the IRQ move. Otherwise, assignment of GRU interrupts on large
systems (>200 cpus) will exhaust the cpu 0 interrupt vectors
and initialization of the GRU driver will fail.

The following fix was initially inspired by David Howells fix
few days back:

  http://lkml.org/lkml/2009/7/9/109

However, Ingo disapproves such fixes as it's dangerous (it can
hide future, relevant warnings) - in something as
performance-uncritical.

So, initialize 'err' to '0' to work around a GCC false positive
warning:

Subject: x86: Fix VMI && stack protector

With CONFIG_STACK_PROTECTOR turned on, VMI doesn't boot with
more than one processor. The problem is with the gs value not
being initialized correctly when registering the secondary
processor for VMI's case.

The patch below initializes the gs value for the AP to
__KERNEL_STACK_CANARY. Without this the secondary processor
keeps on taking a GP on every gs access.

So far, KVM copied the emulated_msrs (only MSR_IA32_MISC_ENABLE) to a
wrong address in user space due to broken pointer arithmetic. This
caused subtle corruption up there (missing MSR_IA32_MISC_ENABLE had
probably no practical relevance). Moreover, the size check for the
user-provided kvm_msr_list forgot about emulated MSRs.

If a migrated vcpu matches the asid_generation value of the target pcpu,
there will be no TLB flush via TLB_CONTROL_FLUSH_ALL_ASID.

The check for vcpu.cpu in pre_svm_run is meaningless since svm_vcpu_load
already updated it on schedule in.

Such vcpu will VMRUN with stale TLB entries.

We have to disable preemption and IRQs on every exit from
handle_invalid_guest_state, otherwise we generate at least a
preempt_disable imbalance.

Subject: KVM: s390: fix wait_queue handling

There are two waitqueues in kvm for wait handling:
vcpu->wq for virt/kvm/kvm_main.c and
vpcu->arch.local_int.wq for the s390 specific wait code.

the wait handling in kvm_s390_handle_wait was broken by using different
wait_queues for add_wait queue and remove_wait_queue.

There are two options to fix the problem:
o  move all the s390 specific code to vcpu->wq and remove
   vcpu->arch.local_int.wq
o  move all the s390 specific code to vcpu->arch.local_int.wq

This patch chooses the 2nd variant for two reasons:
o  s390 does not use kvm_vcpu_block but implements its own enabled wait
   handling.
   Having a separate wait_queue make it clear, that our wait mechanism is
   different
o  the patch is much smaller

Subject: OMAP3: Fixed crash bug with serial + suspend

It was possible for an unhandled interrupt to occur if there was incoming
serial traffic during wakeup from suspend. This was caused by the code
in arch-arm/mach-omap2/serial.c keeping interrupt enabled all the time,
but not acking its interrupts. Applies on top of PM branch.

Use the PM begin/end hooks to ensure that the "serial idle" interrupts
are disabled during the suspend path.  Also, since begin/end hooks are
now used, use the suspend_state that is passed in the begin hook instead
of the enter hook as per the platform_suspend_ops docs.

Subject: OMAP2/3/4: UART: Allow per-UART disabling wakeup for serial ports

This patch causes the OMAP uarts to honor the sysfs power/wakeup file
for IOPAD wakeups. Before the OMAP was always woken up from off mode
on a rs232 signal change.  This patch also creates a different
platform device for each serial port so that the wakeup properties can
be control per port.

By default, IOPAD wakeups are enabled for each UART.  To disable,

  # echo disabled > /sys/devices/platform/serial8250.0/power/wakeup

Where serial8250.0 can be replaced by .1, or .2 to control the other
ports.

Original idea and original patch from Russ Dill <russ.dill@gmail.com>

Use list_add_tail() when adding discovered UART ports.  This is so
traversal using list_for_each_entry() will traverse the list in the

Subject: ARM: 5638/1: arch/arm/kernel/signal.c: use correct address space for
 CRUNCH

preserve_crunch_context() calls __copy_to_user() which expects the
destination address to be in __user space.  setup_sigframe() properly
passes the destination address.

restore_crunch_context() calls __copy_from_user() which expects the
source address to be in __user space.  restore_sigframe() properly
passes the source address.

This fixes {preserve/restore}_crunch_context() to accept the
address as __user space and resolves the following sparse warnings:

Subject: tracing/function-graph-tracer: Drop the useless nmi protection

The function graph tracer used to have a protection against NMI
while entering a function entry tracing. But this is useless now,
this tracer is reentrant and the ring buffer supports the NMI tracing.
We can then drop this protection.

Subject: perf_counter/powerpc: Check oprofile_cpu_type for NULL before using
 it

If the current CPU doesn't support performance counters,
cur_cpu_spec->oprofile_cpu_type can be NULL. The current
perf_counter modules don't test for that case and would thus
crash at boot time.

Bug reported by David Woodhouse.

Subject: [S390] kernel: Storing machine flags early in lowcore

Currently, the machine_flags are stored late in the startup
initialization which results in failing machine type checks
(e.g. for MACHINE_IS_VM).
To allow these checks, store the machine flags in the lowcore
when the machine type has been detected.

Moving the machine_flags to the lowcore has been introduced with
git commit 25097bf153391f7be4c591d47061b3dc4990dac2

OMAP3EVM uses ISP1504 phy which doesn't require any programming and
thus has to use NOP otg transceiver.

Cleanups being done:
	- Remove unwanted code in usb-musb.c file
	- Register NOP in OMAP3EVM board file using
	  usb_nop_xceiv_register().
	- Select NOP_USB_XCEIV for OMAP3EVM boards.
	- Don't enable TWL4030_USB in omap3_evm_defconfig

... it turns out that when trying to enable MSI-X,
__assign_irq_vector(new, cfg_new, apic->target_cpus()) can not
get vector because for x2apic target-cpus returns cpumask_of(0)

Update that to online_mask like xapic.

MacBookPro5,1 is not able to reboot unless reboot=pci is set.
This patch forces it through a DMI quirk specific to this

Subject: perf_counter/powerpc: Fix oops on cpus without perf_counter hardware
 support

If we have the powerpc perf_counter backend compiled in, but
the cpu we are running on is one where we don't support the
PMU, we currently oops in hw_perf_group_sched_in if we try to
use any counters, because ppmu is NULL in that case, and we
unconditionally dereference ppmu.

This fixes the problem by adding a check if ppmu is NULL at the
beginning of hw_perf_group_sched_in, and also at the beginning
of the other functions that get called from the perf_counter
core, i.e. hw_perf_disable, hw_perf_enable, and
hw_perf_counter_setup.

Subject: powerpc/dma: pci_set_dma_mask() shouldn't fail if mask fits in RAM

On an iMac G5, the b43 driver is failing to initialise because trying to
set the dma mask to 30-bit fails. Even though there's only 512MiB of RAM
in the machine anyway:
	https://bugzilla.redhat.com/show_bug.cgi?id=514787

We should probably let it succeed if the available RAM in the system
doesn't exceed the requested limit.

Subject: x86: Fix serialization in pit_expect_msb()

Wei Chong Tan reported a fast-PIT-calibration corner-case:

| pit_expect_msb() is vulnerable to SMI disturbance corner case
| in some platforms which causes /proc/cpuinfo to show wrong
| CPU MHz value when quick_pit_calibrate() jumps to success
| section.

I think that the real issue isn't even an SMI - but the fact
that in the very last iteration of the loop, there's no
serializing instruction _after_ the last 'rdtsc'. So even in
the absense of SMI's, we do have a situation where the cycle
counter was read without proper serialization.

The last check should be done outside the outer loop, since
_inside_ the outer loop, we'll be testing that the PIT has
the right MSB value has the right value in the next iteration.

So only the _last_ iteration is special, because that's the one
that will not check the PIT MSB value any more, and because the
final 'get_cycles()' isn't serialized.

In other words:

 - I'd like to move the PIT MSB check to after the last
   iteration, rather than in every iteration

 - I think we should comment on the fact that it's also a
   serializing instruction and so 'fences in' the TSC read.

Here's a suggested replacement.

Subject: x86, mce: therm_throt - change when we print messages

My Latitude d630 seems to be handling thermal events in SMI by
lowering the max frequency of the CPU till it cools down but
still leaks the "everything is normal" events.

This spams the console and with high priority printks.

Adjust therm_throt driver to only print messages about the fact
that temperatire returned back to normal when leaving the
throttling state.

Also lower the severity of "back to normal" message from
KERN_CRIT to KERN_INFO.

Due to an erratum with certain AMD Athlon 64 processors, the
BIOS may need to force enable the LAHF_LM capability.
Unfortunately, in at least one case, the BIOS does this even
for processors that do not support the functionality.

Add a specific check that will clear the feature bit for
processors known not to support the LAHF/SAHF instructions.

2.6.31-rc kernels don't boot on my ixp4xx box (ds101), because the libata
driver doesn't find the PCI IDE controller any more. 2.6.30 was fine.
I traced this to a PCI update (1f82de10d6b1d845155363c895c552e61b36b51a)
in 2.6.30-git19. Diffing the kernel boot logs from 2.6.30-git18 and
2.6.30-git19 illustrates the breakage:

The specific change in 1f82de10d6b1d845155363c895c552e61b36b51a responsible

Every arch except arm's ixp4xx defines IO_SPACE_LIMIT as an all-bits-one
bitmask, typically -1UL but sometimes only a 16-bit 0x0000ffff. But ixp4xx
defines it as 0xffff0000, which is now causing the PCI failures.

Russell King noted that ixp4xx has 64KB PCI IO space, so IO_SPACE_LIMIT
should be 0x0000ffff. This patch makes that change, which fixes the PCI
failures on my ixp4xx box.

Subject: tracing: Map syscall name to number

Add a new function to support translating a syscall name to number at
runtime.
This allows the syscall event tracer to map syscall names to number.

Subject: tracing: Update FTRACE_SYSCALL_MAX

update FTRACE_SYSCALL_MAX to the current number of syscalls

FTRACE_SYSCALL_MAX is a temporary solution to get the number of
syscalls supported by the arch until we find a more dynamic way
to get this number.

Subject: tracing: Add individual syscalls tracepoint id support

The current state of syscalls tracepoints generates only one event id
for every syscall events.

This patch associates an id with each syscall trace event, so that we
can identify each syscall trace event using the 'perf' tool.

Subject: tracing: Convert x86_64 mmap and uname to use DEFINE_SYSCALL

A number of syscalls are not using 'DEFINE_SYSCALL'. I'm not sure why.
Convert x86_64 uname and mmap to use DEFINE_SYSCALL.

Subject: Bug Fix arch/ia64/kernel/pci-dma.c: fix recursive dma_supported()
 call in iommu_dma_supported()

In commit 160c1d8e40866edfeae7d68816b7005d70acf391,
dma_ops->dma_supported = iommu_dma_supported;

This dma_ops->dma_supported is first called in platform_dma_init() during kernel
boot. Then dma_ops->dma_supported will be called recursively in
iommu_dma_supported.

Kernel can not boot because kernel can not get out of iommu_dma_supported until
it runs out of stack memory.

Subject: arch/ia64/Makefile: Remove -mtune=merced in IA64 kernel build

Between GCC version 3.4.0 and 4.3.3 (including 3.4.0 and 4.3.3), -mtune=merced
is implemented in GCC. Starting from 4.4.0, -mtune=merced is deprecated.

Even implemented in versions between 3.4.0 and 4.3.3, the -mtune=merced
feature has been broken in some of the versions. For example, GCC 4.1.2 reports
interanl tuning function errors during kernel building with -mtune=merced. Or
GCC Bugzilla 16130 reports another -mtune=merced issue on GCC 3.4.1.

So I would remove the -mtune=merced from IA64 kernel build. Without this option,
kernel on Merced will remain the same except losing an unstable and out-of-date
performance tunning feature.

Since GCC version 3.4.0, -mtune=mckinley has been implemented. The
-mtune=mckinley option functions the same as mtune=itanium2. And mtune=itanium2
is the default option. So we don't need to add mtune=mckinley either since its
been the default option in any GCC version which implements this option.

Subject: x86: Fix oops in identify_cpu() on CPUs without CPUID

Kernel is broken for x86 CPUs without CPUID since 2.6.28. It
crashes with NULL pointer dereference in identify_cpu():

766        generic_identify(c);
767
768-->     if (this_cpu->c_identify)
769               this_cpu->c_identify(c);

this_cpu is NULL. This is because it's only initialized in
get_cpu_vendor() function, which is not called if the CPU has
no CPUID instruction.

Subject: perf_counter, x86: Fix/improve apic fallback

Johannes Stezenbach reported that his Pentium-M based
laptop does not have the local APIC enabled by default,
and hence perfcounters do not get initialized.

Add a fallback for this case: allow non-sampled counters
and return with an error on sampled counters. This allows
'perf stat' to work out of box - and allows 'perf top'
and 'perf record' to fall back on a hrtimer based sampling
method.

( Passing 'lapic' on the boot line will allow hardware
  sampling to occur - but if the APIC is disabled
  permanently by the hardware then this fallback still
  allows more systems to use perfcounters. )

Also decouple perfcounter support from X86_LOCAL_APIC.

-v2: fix typo breaking counters on all other systems ...

From ba9a633787eed1e90d587282642580ad3d44f7fd Mon Sep 17 00:00:00 2001

Subject: sh: convert processor device setup functions to arch_initcall()

Convert the processor platform device setup
functions from __initcall() and sometimes
device_initcall() to arch_initcall().

This makes sure that the platform devices are
registered a bit earlier so the devices are
available when drivers register using initcall
levels earlier than device_initcall().

A good example is platform devices needed by
i2c-sh_mobile.c which registers a bit earlier
using subsys_initcall().

Subject: percpu, sparc64: fix sparse possible cpu map handling

percpu code has been assuming num_possible_cpus() == nr_cpu_ids which
is incorrect if cpu_possible_map contains holes.  This causes percpu
code to access beyond allocated memories and vmalloc areas.  On a
sparc64 machine with cpus 0 and 2 (u60), this triggers the following
warning or fails boot.

 ---[ end trace 429b268a213317ba ]---

This patch fixes generic percpu functions and sparc64
setup_per_cpu_areas() so that they handle sparse cpu_possible_map
properly.

Please note that on x86, cpu_possible_map() doesn't contain holes and
thus num_possible_cpus() == nr_cpu_ids and this patch doesn't cause
any behavior difference.

Small confusion with our hardware engineer, the WP signal (RO) is
active low on our boards, the signal has to inverted.

This is a pretty straightforward patch, it could even go to -rc,
but if not, then push it for 2.6.32.

Subject: sh: use in-soc KEYSC on se7724

This patch updates the Solution Engine 7724 board code to use
in-SoC KEYSC resources for the keyboard platform device. Using
the in-SoC key scan controller fixes a crash-during-resume issue.

Without this patch the KEYSC hardware block located in the board
specific FPGA is used together with an external IRQ which is
routed through the FPGA and handled by some board specific demux
code. This board specific FPGA interrupt code does not implement
desc->set_wake() so the enable_irq_wake() call in the sh_keysc
driver will fail at suspend-to-ram time and the disable_irq_wake()
will bomb out when resuming.

Changing the platform data to use the in-SoC KEYSC hardware makes
the se7724 board support code less special which is a good thing.
Also, the board specific KEYSC pin setup code selects in-SoC pin
functions already which makes the current FPGA platform device data
look like a typo.

This patch updates the SuperH Mobile sleep assembly code with
support for DBSC memory controller found in the sh7724 processor.

Without this fix the memory hooked up to the sh7724 processor
will never enter self-refresh mode before suspending to ram. The
effect of this is that the memory contents most likeley will be
lost upon resume which may or may not be what you want.

Subject: x86: Fix UV BAU destination subnode id

The SGI UV Broadcast Assist Unit is used to send TLB shootdown
messages to remote nodes of the system.  The header of the
message must contain the subnode id of the block in the
receiving hub that handles such messages.  It should always be
0x10, the id of the "LB" block.

It had previously been documented as a "must be zero" field.

Subject: ARM: Fix broken highmem support

Currently, highmem is selectable, and you can request an increased
vmalloc area.  However, none of this has any effect on the memory
layout since a patch in the highmem series was accidentally dropped.
Moreover, even if you did want highmem, all memory would still be
registered as lowmem, possibly resulting in overflow of the available
virtual mapping space.

The highmem boundary is determined by the highest allowed beginning
of the vmalloc area, which depends on its configurable minimum size
(see commit 60296c71f6c5063e3c1f1d2619ca0b60940162e7 for details on
this).

We should create mappings and initialize bootmem only for low memory,
while the zone allocator must still be told about highmem.

Currently, memory nodes which are completely located in high memory
are not supported.  This is not a huge limitation since systems
relying on highmem support are unlikely to have discontiguous memory
with large holes.

[ A similar patch was meant to be merged before commit 5f0fbf9ecaf3
  and be available  in Linux v2.6.30, however some git rebase screw-up
  of mine dropped the first commit of the series, and that goofage
  escaped testing somehow as well. -- Nico ]

Subject: x86, mce: don't log boot MCEs on Pentium M (model == 13) CPUs

On my legacy Pentium M laptop (Acer Extensa 2900) I get bogus MCE on a cold
boot with CONFIG_X86_NEW_MCE enabled, i.e. (after decoding it with mcelog):

MCE 0
HARDWARE ERROR. This is *NOT* a software problem!
Please contact your hardware vendor
CPU 0 BANK 1 MCG status:
MCi status:
Error overflow
Uncorrected error
Error enabled
Processor context corrupt
MCA: Data CACHE Level-1 UNKNOWN Error
STATUS f200000000000195 MCGSTATUS 0

[ The other STATUS values observed: f2000000000001b5 (... UNKNOWN error)
  and f200000000000115 (... READ Error).

  To verify that this is not a CONFIG_X86_NEW_MCE bug I also modified
  the CONFIG_X86_OLD_MCE code (which doesn't log any MCEs) to dump
  content of STATUS MSR before it is cleared during initialization. ]

Since the bogus MCE results in a kernel taint (which in turn disables
lockdep support) don't log boot MCEs on Pentium M (model == 13) CPUs
by default ("mce=bootlog" boot parameter can be be used to get the old
behavior).

Subject: x86, mce: Don't initialize MCEs on unknown CPUs

An older test-box started hanging at the following point during
bootup:

 [    0.022996] Mount-cache hash table entries: 512
 [    0.024996] Initializing cgroup subsys debug
 [    0.025996] Initializing cgroup subsys cpuacct
 [    0.026995] Initializing cgroup subsys devices
 [    0.027995] Initializing cgroup subsys freezer
 [    0.028995] mce: CPU supports 5 MCE banks

I've bisected it down to commit 4efc0670 ("x86, mce: use 64bit
machine check code on 32bit"), which utilizes the MCE code on
32-bit systems too.

The problem is caused by this detail in my config:

  # CONFIG_CPU_SUP_INTEL is not set

This disables the quirks in mce_cpu_quirks() but still enables
MCE support - which then hangs due to the missing quirk
workaround needed on this CPU:

	if (c->x86 == 6 && c->x86_model < 0x1A && banks > 0)
		mce_banks[0].init = 0;

The safe solution is to not initialize MCEs if we dont know on
what CPU we are running (or if that CPU's support code got
disabled in the config).

Also be a bit more defensive on 32-bit systems: dont do a
boot-time dump of pending MCEs not just on the specific system
that we found a problem with (Pentium-M), but earlier ones as
well.

Now this problem is probably not common and disabling CPU
support is rare - but still being more defensive in something
we turned on for a wide range of CPUs is prudent.

PAT code maps the ISA memory range as WB in the PAT attribute, so that
fixed range MTRR registers define the actual memory type (UC/WC/WT etc).

But the upper level is_new_memtype_allowed() API checks are failing,
as the request here is for UC and the return tracked type is WB (Tracked type is
WB as MTRR type for this legacy range potentially will be different for each
4k page).

Fix is_new_memtype_allowed() by always succeeding the ISA address range
checks, as the null PAT (WB) and def MTRR fixed range register settings
satisfy the memory type needs of the applications that map the ISA address
range.

This code path doesn't test any returned pointers for NULL, leading to a bad

Slightly better is to BUG(), but even better still would be a printk beforehand.

Subject: microblaze: Use klimit instead of _end for memory init

For noMMU system when you use larger rootfs image
there is problem with using _end label because
we increase klimit but in memory initialization
we use still _end which is wrong. Larger mtd rootfs
was rewritten by init_bootmem_node.

MMU kernel use static initialization where klimit
is setup to _end. There is no any other hanling
with klimit.

Subject: i386: Fix section mismatches for init code with !HOTPLUG_CPU

Commit 0e83815be719d3391bf5ea24b7fe696c07dbd417 changed the
section the initial_code variable gets allocated in, in an
attempt to address a section conflict warning. This, however
created a new section conflict when building without
HOTPLUG_CPU. The apparently only (reasonable) way to address
this is to always use __REFDATA.

Once at it, also fix a second section mismatch when not using
HOTPLUG_CPU.

Subject: sparc: sys32.S incorrect compat-layer splice() system call

I think arch/sparc/kernel/sys32.S has an incorrect splice definition:

SIGN2(sys32_splice, sys_splice, %o0, %o1)

The splice() prototype looks like :

       long splice(int fd_in, loff_t *off_in, int fd_out,
                   loff_t *off_out, size_t len, unsigned int flags);

So I think we should have :

SIGN2(sys32_splice, sys_splice, %o0, %o2)

Subject: sparc32: Kill trap table freeing code.

Normally, srmmu uses different trap table register values to allow
determination of the cpu we're on.  All of the trap tables have
identical content, they just sit at different offsets from the first
trap table, and the offset shifted down and masked out determines
the cpu we are on.

The code tries to free them up when they aren't actually used
(don't have all 4 cpus, we're on sun4d, etc.) but that causes
problems.

For one thing it triggers false positives in the DMA debugging
code.  And fixing that up while preserving this relative offset
thing isn't trivial.

So just kill the freeing code, it costs us at most 3 pages, big
deal...

Subject: [S390] ftrace: update system call tracer support

Commit fb34a08c3 ("tracing: Add trace events for each syscall
entry/exit") changed the lowlevel API to ftrace syscall tracing
but did not update s390 which started making use of it recently.

This broke the s390 build, as reported by Paul Mundt.

Update the callbacks with the syscall number and the syscall
return code values. This allows per syscall tracepoints,
syscall argument enumeration /debug/tracing/events/syscalls/
and perfcounters support and integration on s390 too.

Subject: clockevent: Prevent dead lock on clockevents_lock

Currently clockevents_notify() is called with interrupts enabled at
some places and interrupts disabled at some other places.

This results in a deadlock in this scenario.

cpu A holds clockevents_lock in clockevents_notify() with irqs enabled
cpu B waits for clockevents_lock in clockevents_notify() with irqs disabled
cpu C doing set_mtrr() which will try to rendezvous of all the cpus.

This will result in C and A come to the rendezvous point and waiting
for B. B is stuck forever waiting for the spinlock and thus not
reaching the rendezvous point.

Fix the clockevents code so that clockevents_lock is taken with
interrupts disabled and thus avoid the above deadlock.

Also call lapic_timer_propagate_broadcast() on the destination cpu so
that we avoid calling smp_call_function() in the clockevents notifier
chain.

This issue left us wondering if we need to change the MTRR rendezvous
logic to use stop machine logic (instead of smp_call_function) or add
a check in spinlock debug code to see if there are other spinlocks
which gets taken under both interrupts enabled/disabled conditions.

Subject: x86: make sure load_percpu_segment has no stackprotector

load_percpu_segment() is used to set up the per-cpu segment registers,
which are also used for -fstack-protector.  Make sure that the
load_percpu_segment() function doesn't have stackprotector enabled.

[ Impact: allow percpu setup before calling stack-protected functions ]

Subject: x86: don't send an IPI to the empty set of CPU's
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The default_send_IPI_mask_logical() function uses the "flat" APIC mode
to send an IPI to a set of CPU's at once, but if that set happens to be
empty, some older local APIC's will apparently be rather unhappy.  So
just warn if a caller gives us an empty mask, and ignore it.

This fixes a regression in 2.6.30.x, due to commit 4595f9620 ("x86:
change flush_tlb_others to take a const struct cpumask"), documented
here:

	http://bugzilla.kernel.org/show_bug.cgi?id=13933

which causes a silent lock-up.  It only seems to happen on PPro, P2, P3
and Athlon XP cores.  Most developers sadly (or not so sadly, if you're
a developer..) have more modern CPU's.  Also, on x86-64 we don't use the
flat APIC mode, so it would never trigger there even if the APIC didn't
like sending an empty IPI mask.

Subject: x86: don't call '->send_IPI_mask()' with an empty mask
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As noted in 83d349f35e1ae72268c5104dbf9ab2ae635425d4 ("x86: don't send
an IPI to the empty set of CPU's"), some APIC's will be very unhappy
with an empty destination mask.  That commit added a WARN_ON() for that
case, and avoided the resulting problem, but didn't fix the underlying
reason for why those empty mask cases happened.

This fixes that, by checking the result of 'cpumask_andnot()' of the
current CPU actually has any other CPU's left in the set of CPU's to be
sent a TLB flush, and not calling down to the IPI code if the mask is
empty.

The reason this started happening at all is that we started passing just
the CPU mask pointers around in commit 4595f9620 ("x86: change
flush_tlb_others to take a const struct cpumask"), and when we did that,
the cpumask was no longer thread-local.

Before that commit, flush_tlb_mm() used to create it's own copy of
'mm->cpu_vm_mask' and pass that copy down to the low-level flush
routines after having tested that it was not empty.  But after changing
it to just pass down the CPU mask pointer, the lower level TLB flush
routines would now get a pointer to that 'mm->cpu_vm_mask', and that
could still change - and become empty - after the test due to other
CPU's having flushed their own TLB's.

See

	http://bugzilla.kernel.org/show_bug.cgi?id=13933

for details.

setup_arch() unconditionally sets the preferred console to ttyS.
This breaks the use of 3270 devices as the console. Provide a new

console depends on the conmode parameter that is used to switch
between 3270 and 3215 terminal/console mode.

Subject: x86: Fix an incorrect argument of reserve_bootmem()

This line looks suspicious, because if this is true, then the
'flags' parameter of function reserve_bootmem_generic() will be
unused when !CONFIG_NUMA. I don't think this is what we want.

Subject: x86: Fix build with older binutils and consolidate linker script

binutils prior to 2.17 can't deal with the currently possible
situation of a new segment following the per-CPU segment, but
that new segment being empty - objcopy misplaces the .bss (and
perhaps also the .brk) sections outside of any segment.

However, the current ordering of sections really just appears
to be the effect of cumulative unrelated changes; re-ordering
things allows to easily guarantee that the segment following
the per-CPU one is non-empty, and at once eliminates the need
for the bogus data.init2 segment.

Once touching this code, also use the various data section
helper macros from include/asm-generic/vmlinux.lds.h.

-v2: fix !SMP builds.

Subject: tracing: Rename FTRACE_SYSCALLS for tracepoints

s/HAVE_FTRACE_SYSCALLS/HAVE_SYSCALL_TRACEPOINTS/g
s/TIF_SYSCALL_FTRACE/TIF_SYSCALL_TRACEPOINT/g

The syscall enter/exit tracing is no longer specific to just ftrace, so
they now have names that reflect their tie to tracepoints instead.

Subject: tracing: Move tracepoint callbacks from declaration to definition

It's not strictly correct for the tracepoint reg/unreg callbacks to
occur when a client is hooking up, because the actual tracepoint may not
be present yet.  This happens to be fine for syscall, since that's in
the core kernel, but it would cause problems for tracepoints defined in
a module that hasn't been loaded yet.  It also means the reg/unreg has
to be EXPORTed for any modules to use the tracepoint (as in SystemTap).

This patch removes DECLARE_TRACE_WITH_CALLBACK, and instead introduces
DEFINE_TRACE_FN which stores the callbacks in struct tracepoint.  The
callbacks are used now when the active state of the tracepoint changes
in set_tracepoint & disable_tracepoint.

This also introduces TRACE_EVENT_FN, so ftrace events can also provide
registration callbacks if needed.

Subject: tracing: Create generic syscall TRACE_EVENTs

This converts the syscall_enter/exit tracepoints into TRACE_EVENTs, so
you can have generic ftrace events that capture all system calls with
arguments and return values.  These generic events are also renamed to
sys_enter/exit, so they're more closely aligned to the specific
sys_enter_foo events.

Subject: sparc64: Validate linear D-TLB misses.

When page alloc debugging is not enabled, we essentially accept any
virtual address for linear kernel TLB misses.  But with kgdb, kernel
address probing, and other facilities we can try to access arbitrary
crap.

So, make sure the address we miss on will translate to physical memory
that actually exists.

In order to make this work we have to embed the valid address bitmap
into the kernel image.  And in order to make that less expensive we
make an adjustment, in that the max physical memory address is
decreased to "1 << 41", even on the chips that support a 42-bit
physical address space.  We can do this because bit 41 indicates
"I/O space" and thus covers non-memory ranges.

The result of this is that:

1) kpte_linear_bitmap shrinks from 2K to 1K in size

2) we need 64K more for the valid address bitmap

We can't let the valid address bitmap be dynamically allocated
once we start using it to validate TLB misses, otherwise we have
crazy issues to deal with wrt. recursive TLB misses and such.

If we're in a TLB miss it could be the deepest trap level that's legal
inside of the cpu.  So if we TLB miss referencing the bitmap, the cpu
will be out of trap levels and enter RED state.

To guard against out-of-range accesses to the bitmap, we have to check
to make sure no bits in the physical address above bit 40 are set.  We
could export and use last_valid_pfn for this check, but that's just an
unnecessary extra memory reference.

On the plus side of all this, since we load all of these translations
into the special 4MB mapping TSB, and we check the TSB first for TLB
misses, there should be absolutely no real cost for these new checks
in the TLB miss path.

Subject: x86, xen: Suppress WP test on Xen

Xen always runs on CPUs which properly support WP enforcement in
privileged mode, so there's no need to test for it.

This also works around a crash reported by Arnd Hannemann, though I
think its just a band-aid for that case.

| commit 2759c3287de27266e06f1f4e82cbd2d65f6a044c
| x86: don't call read_apic_id if !cpu_has_apic

The problem is that on vSMP systems the CPUID derived
initial-APICIDs are overlapping - so we need to fall
back on hard_smp_processor_id() which reads the local
APIC.

Both come from the hardware (influenced by firmware
though) so it's a tough call which one to trust.

Doing the quirk expresses the vSMP property properly
and also does not affect other systems, so we go for
this solution instead of a revert.

Subject: tracing: Add syscall tracepoints - s390 arch update

This patch includes s390 arch updates to synchronize with latest
core changes in the syscalls tracing area.

- tracing: Map syscall name to number (syscall_name_to_nr())
- tracing: Call arch_init_ftrace_syscalls at boot
- tracing: add support tracepoint ids (set_syscall_{enter,exit}_id())

Subject: tracing: Define NR_syscalls for x86 (32)

Add a NR_syscalls #define for x86. This is used in the syscall events
tracing code. Todo: make it dynamic like x86_64.

NR_syscalls is the usual name used to determine the number of syscalls
supported by the current arch. We want to unify the use of this number
across archs that support the syscall tracing. This also prepare to move
some of the arch code to core code in the syscall tracing area.

Subject: tracing: Define NR_syscalls for x86_64

Express the available number of syscalls in a standard way by defining
NR_syscalls.

The common way to define it is to place its definition in asm/unistd.h
However, the number of syscalls is defined using __NR_syscall_max in
x86-64 after building a dynamic header file "asm-offsets.h"

The source file that generates this header, asm-offsets-64.c includes
unistd.h, then if we want to express NR_syscalls from __NR_syscall_max
in unistd.h only after generating the dynamic header file, we need a
watchguard.

If unistd.h is included from asm-offsets-64.c, then we are generating
asm-offset.h which defines __NR_syscall_max. At this time, we don't
want to (we can't) define NR_syscalls, then we do nothing.
Otherwise we define NR_syscalls because we know asm-offsets.h has
been generated.

Subject: tracing: Convert event tracing code to use NR_syscalls

Convert the syscalls event tracing code to use NR_syscalls, instead of
FTRACE_SYSCALL_MAX. NR_syscalls is standard accross most arches, and
reduces code confusion/complexity.

Subject: powerpc/ps3: Add missing check for PS3 to rtc-ps3 platform device
 registration

On non-PS3, we get:

| kernel BUG at drivers/rtc/rtc-ps3.c:36!

because the rtc-ps3 platform device is registered unconditionally in a kernel
with builtin support for PS3.

Subject: [IA64] fix csum_ipv6_magic()

The 32-bit parameters (len and csum) of csum_ipv6_magic() are passed in 64-bit
registers in2 and in4. The high order 32 bits of the registers were never
cleared, and garbage was sometimes calculated into the checksum.

Fix this by clearing the high order 32 bits of these registers.

Subject: sparc64: Kill spurious NMI watchdog triggers by increasing limit to
 30 seconds.

This is a compromise and a temporary workaround for bootup NMI
watchdog triggers some people see with qla2xxx devices present.

This happens when, for example:

CPU 0 is in the driver init and looping submitting mailbox commands to
load the firmware, then waiting for completion.

CPU 1 is receiving the device interrupts.  CPU 1 is where the NMI
watchdog triggers.

CPU 0 is submitting mailbox commands fast enough that by the time CPU
1 returns from the device interrupt handler, a new one is pending.
This sequence runs for more than 5 seconds.

The problematic case is CPU 1's timer interrupt running when the
barrage of device interrupts begin.  Then we have:

	timer interrupt
	return for softirq checking
	pending, thus enable interrupts

		 qla2xxx interrupt
		 return
		 qla2xxx interrupt
		 return
		 ... 5+ seconds pass
		 final qla2xxx interrupt for fw load
		 return

	run timer softirq
	return

At some point in the multi-second qla2xxx interrupt storm we trigger
the NMI watchdog on CPU 1 from the NMI interrupt handler.

The timer softirq, once we get back to running it, is smart enough to
run the timer work enough times to make up for the missed timer
interrupts.

However, the NMI watchdogs (both x86 and sparc) use the timer
interrupt count to notice the cpu is wedged.  But in the above
scenerio we'll receive only one such timer interrupt even if we last
all the way back to running the timer softirq.

The default watchdog trigger point is only 5 seconds, which is pretty
low (the softwatchdog triggers at 60 seconds).  So increase it to 30
seconds for now.

Subject: sparc64: Fix bootup with mcount in some configs.

Functions invoked early when booting up a cpu can't use
tracing because mcount requires a valid 'current_thread_info()'
and TLB mappings to be setup.

The code path of sun4v_register_mondo_queues --> register_one_mondo
is one such case.  sun4v_register_mondo_queues already has the
necessary 'notrace' annotation, but register_one_mondo does not.

Normally register_one_mondo is inlined so the bug doesn't trigger,
but with some config/compiler combinations, it won't be so we
must properly mark it notrace.

While we're here, add 'notrace' annoations to prom_printf and
prom_halt so that early error handling won't have the same problem.
