This code elsewhere returns a negative constant to an indicate an error,
while IS_ERR returns the result of a >= operation.
The semantic patch that fixes this problem is as follows:

expression x;

if (...) { ...

Commit 03a9e5126147c9f92aeba4b34f62b15b625087fb
(omap1: Use asm_irq_flags for entry-macro.S) added support
for multi-omap builds with addition of the omap_irq_flags.
Commit 9f9605c2eda9679e6f63c605cbd9cbf6a9a7f3fa
(omap2+: Fix unused variable warning for omap_irq_base)
simplified omap2+ entry-macro.S by moving omap_irq_flags
out of entry-macro.S.
Simplify omap1 entry-macro.S in a similar way to keep the
code consistent. Based on a similar earlier patch for omap2+
by Russell King <rmk+kernel@arm.linux.org.uk>.

Commit 5d190c40100793a6dfc37bf325677c10f3c80edf
(omap2+: Initialize omap_irq_base for entry-macro.S from
platform code) simplified the handling of omap_irq_base
for multi-omap builds. However, this patch also introduced
a build warning for !MULTI_OMAP2 builds:
arch/arm/mach-omap2/io.c: In function 'omap_irq_base_init':
arch/arm/mach-omap2/io.c:322: warning: unused variable 'omap_irq_base'
Fix this by removing the ifdef. Also simplify things further
by moving omap_irq_base out of entry-macro.S.

The -rt patches change the console_semaphore to console_mutex. As a
result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()
This commit makes things use more neutral function names which dont make
implications about the underlying lock.
The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()
This patch also paves the way to switching console_sem from a semaphore to
a mutex.

This fixes TRANSPARENT_HUGEPAGE=y with PARAVIRT=y and HIGHMEM64=n.
The #ifdef that this patch removes was erratically introduced to fix a
build error for noPAE (where pmd.pmd doesn't exist). So then the kernel
built but it failed at runtime because set_pmd_at was a noop. This will
correct it by enabling set_pmd_at for noPAE mode too.

The EP93xx C and D GPIO ports are multiplexed with the Keypad Interface
peripheral. At power-up they default into non-GPIO mode with the Key
Matrix controller enabled so these ports are unusable for GPIO. Note
that the Keypad Interface peripheral is only available in the EP9307,
EP9312, and EP9315 processor variants.
The keypad support will clear the DeviceConfig bits appropriately to
enable the Keypad Interface when the driver is loaded. And, when the
driver is unloaded it will set the bits to return the ports to GPIO mode.
To make these ports available for GPIO after power-up on all EP93xx
processor variants, set the KEYS and GONK bits in the DeviceConfig
register.
Similarly, the E, G, and H ports are multiplexed with the IDE Interface
peripheral. At power-up these also default into non-GPIO mode. Note
that the IDE peripheral is only available in the EP9312 and EP9315
processor variants.
Since an IDE driver is not even available in mainline, set the EONIDE,
GONIDE, and HONIDE bits in the DeviceConfig register so that these
ports will be available for GPIO use after power-up.

Timers on Versatile Express mainboard are used as system clock/event
sources. Driver assumes that they are clocked with 1MHz signal.
Old V2M firmware apparently configured it by default, but on newer
boards one can observe that "sleep 1" command takes over 30 seconds
to finish, as the timers are fed with 32kHz instead...
This patch performs required magic and also removes code clearing
timer's control registers, as exactly the same operations are
performed by the timer driver few jiffies later.

As no one seems to really know which configuration options tie up with
which boards, I thought I'd do some investigation and try to work it
out. After discussion with some folk in linaro, I think I have this
nailed.
The names are updated to use the name on the front of the appropriate
board user guide for the various baseboards, which I've taken to be
the official name for each board.
I haven't significantly updated the descriptions for the tiles as that
is even less clear - as far as I can see on ARMs website, there is no
Cortex-A9 tile for Realview EB - only ARM11MPCore, ARM1156T2F-S,
ARM1176TZF-S and Cortex-R4F. So exactly what this 'Multicore Cortex-A9
Tile' is...

This is often because write_pen_release lacks a __cpuinitdata

`debug=mem' on Amiga has been broken for a while.
early_param() processing is done very/too early, i.e. before
amiga_identify() / amiga_chip_init(), causing amiga_savekmsg_setup() not
to find any Chip RAM.
As we don't plan to free this memory anyway, just steal it from the initial
Chip RAM memory block instead.

Some versions of gcc replace calls to strstr() with single-character
"needle" string parameters by calls to strchr() behind our back.
If strchr() is defined as an inline function, this causes linking errors
like
ERROR: "strchr" [drivers/target/target_core_mod.ko] undefined!
As m68k is the only architecture that has an inline strchr() and this
inline version is not an optimized asm version, uninline strchr() and use
the standard out-of-line C version in lib/string.c instead.
This also decreases the defconfig/allmodconfig kernel image sizes by a few
hundred bytes.

ea53069231f9317062910d6e772cca4ce93de8c8 made a CPU use monitor/mwait
when offline. This is not the optimal choice for AMD wrt to powersavings
and we'd prefer our cores to halt (i.e. enter C1) instead. For this, the
same selection whether to use monitor/mwait has to be used as when we
select the idle routine for the machine.
With this patch, offlining cores 1-5 on a X6 machine allows core0 to
boost again.

After changing the p2m mapping to a tree by
commit 58e05027b530ff081ecea68e38de8d59db8f87e0
xen: convert p2m to a 3 level tree
and trying to boot a DomU with 615MB of memory, the following crash was
observed in the dump:
kernel direct mapping tables up to 26f00000 @ 1ec4000-1fff000
BUG: unable to handle kernel NULL pointer dereference at (null)
IP: [<c0107397>] xen_set_pte+0x27/0x60
*pdpt = 0000000000000000 *pde = 0000000000000000
Adding further debug statements showed that when trying to set up
pfn=0x26700 the returned mapping was invalid.
pfn=0x266ff calling set_pte(0xc1fe77f8, 0x6b3003)
pfn=0x26700 calling set_pte(0xc1fe7800, 0x3)
Although the last_pfn obtained from the startup info is 0x26700, which
should in turn not be hit, the additional 8MB which are added as extra
memory normally seem to be ok. This lead to looking into the initial
p2m tree construction, which uses the smaller value and assuming that
there is other code handling the extra memory.
When the p2m tree is set up, the leaves are directly pointed to the
array which the domain builder set up. But if the mapping is not on a
boundary that fits into one p2m page, this will result in the last leaf
being only partially valid. And as the invalid entries are not
initialized in that case, things go badly wrong.
I am trying to fix that by checking whether the current leaf is a
complete map and if not, allocate a completely new page and copy only
the valid pointers there. This may not be the most efficient or elegant
solution, but at least it seems to allow me booting DomUs with memory
assignments all over the range.

coretemp to handler intr
In therm_throt.c, commit
9e76a97efd31a08cb19d0ba12013b8fb4ad3e474 patch doesn't export
the symbol platform_thermal_notify.
Other drivers (e.g. drivers/hwmon/coretemp.c) can not find the
symbol platform_thermal_notify when defining threshould
interrupt handler.
Please apply this patch to allow threshold interrupt handler in
coretemp.
