Subject: gma500: mark staging broken

It now clashes with upstream DRM which we don't want to block.

We don't want to delete this code just yet as we want to keep it for
comparison and reference when debugging, but soon it will be a removal
candidate as well

Subject: staging/mei: fix check for allocating host client id

MEI_CLIENTS_MAX is 255 and host_client_id is u8 therefore
for check to work we need to first assign the return value
of find_first_zero_bit to unsigned long variable

Subject: line6: fix memory leaks in line6_init_midi()

If the first call to line6_midibuf_init() fails we'll leak a little
bit of memory. If the second call fails we'll leak a bit more. This
happens when we return from the function and the local variable
'line6midi' goes out of scope.

Subject: staging: line6: add Pod HD300 support

The Pod HD device family uses new MIDI SysEx messages and therefore
cannot reuse the existing Pod code.  Instead of hardcoding Pod HD MIDI
messages into the driver, leave MIDI up to userspace.  This driver
simply presents MIDI and pcm ALSA devices.

This device is similar to the Pod except that it has 48 kHz audio and
does not respond to Pod SysEx messages.

The driver leaves MIDI processing up to userspace for the POD HD300
device.  Add a missing case statement to skip MIDI postprocessing in the

Subject: staging: line6: use smallest iso ep packet size

The POD HD300 isochronous endpoints have different max packet sizes for
read and write.  Using the read endpoint max packet size may be too
large for the write endpoint.  Instead we should use the minimum of both
endpoints to be sure the size is acceptable.

In theory we could decouple read and write packet sizes but the driver
currently uses a single size which I chose not to mess with since other
features like software monitoring may depend on a single packet size for
both endpoints.

Subject: staging: line6: alloc/free buffers in hw_params/hw_free

It is unsafe to free buffers in line6_pcm_stop(), which is not allowed
to sleep, since urbs cannot be killed completely there and only
unlinked.  This means I/O may still be in progress and the URB
completion function still gets invoked.  This may result in memory
corruption when buffer_in is freed but I/O is still pending.

Additionally, line6_pcm_start() is not supposed to sleep so it should
not use kmalloc(GFP_KERNEL).

These issues can be resolved by performing buffer allocation/freeing in
the .hw_params/.hw_free callbacks instead.  The ALSA documentation also
recommends doing buffer allocation/freeing in these callbacks.

Subject: staging: et131x: Remove section comments

Following the move to put the driver into one file, comments were added to identify which source file each set of functions originated from.
These no longer made sense after functions were moved around to remove some forward declarations, so remove them.

A function comment was previously not moved along with its function, now they are reunited.

From e15fbc91a4304a977ed99c3eb21bab7015e86c11 Mon Sep 17 00:00:00 2001

Subject: iio: introduce type casts to avoid __ucmpdi2 calls

This patch type casts the switch control variable to 32 bits in order to
prevent a call __ucmpdi2 generated by some versions of gcc.

This fixes an undefined reference to `__ucmpdi2' when compiled for arch/blackfin

 val

Postenable and predisable are called via buffer->ops so  don't
need to check if buffer exists.

The return value of iio_device_register_trigger_consumer is
always zero and it isn't checked anyway so get rid of it.

Subject: staging:iio:kfifo remove entirely pointless code.

I really don't want to think about how this bit got
in there.  It allocates some storage - copies something
into it then frees it without making use of it.
Oops.

Subject: staging:iio: core. Allow for event chrdev obtaining ioctl if no
 buffer present.

Logic bug meant the chrdev would fail to open if there was no buffer support
in a driver or in the core. This meant the ioctl to get the event chrdev
would fail and hence events were not available.

V2: change error to -EINVAL to mark as unsuitable for reading rather than
not there.  Both are true depending on how you look at it.

Subject: staging:iio: header reorganization

Issue brought up by Lars-Peter Clausen. This is a varient of what
he suggested.

io/iio.h for driver stuff (has to include types.h)
	Sub files for the bits drivers may or may not use
	iio/sysfs.h
	iio/buffer.h (contents of current buffer_generic.h)
	(obviously anything offering events will need events.h as well)
iio/types.h for the enums that matter to both
	iio_chan_type, iio_modifier
iio/events.h for the event code stuff
	IIO_EVENT_CODE and friends.  + everything in chrdev.h  So this
	is the stuff that userspace cares about.
	Also include iio_event_type, iio_event_direction

Thus iio drivers include iio.h + as required
events.h
sysfs.h
buffer.h

in kernel users (once that interface is merged) will need inkern.h
which will pull in types.h

Userspace will need just events.h (which pulls in types.h) to get
everything they need to know about.  Buffer userspace access doesn't
currently need any core defines. All information about the data
format is passed through sysfs.

- * struct iio_buffer_access_funcs - access functions for buffers.
- * @mark_in_use:	reference counting, typically to prevent module removal
- * @unmark_in_use:	reduce reference count when no longer using buffer
- * @store_to:		actually store stuff to the buffer
- * @read_last:		get the last element stored
- * @read_first_n:	try to get a specified number of elements (must exist)
- * @mark_param_change:	notify buffer that some relevant parameter has changed
- *			Often this means the underlying storage may need to
- *			change.
- * @request_update:	if a parameter change has been marked, update underlying
- *			storage.
- * @get_bytes_per_datum:get current bytes per datum
- * @set_bytes_per_datum:set number of bytes per datum
- * @get_length:		get number of datums in buffer
- * @set_length:		set number of datums in buffer
- * @is_enabled:		query if buffer is currently being used
- * @enable:		enable the buffer
- *
- * The purpose of this structure is to make the buffer element
- * modular as event for a given driver, different usecases may require
- * different buffer designs (space efficiency vs speed for example).
- *
- * It is worth noting that a given buffer implementation may only support a
- * small proportion of these functions.  The core code 'should' cope fine with
- * any of them not existing.

Subject: staging:iio: Do not use bitmasks for channel info addresses

Currently the iio framework uses bitmasks for the address field of channel info
attributes. This is for historical reasons and no longer required since it will
only ever query a single info attribute at once. This patch changes the code to
use the non-shifted iio_chan_info_enum values for the info attribute address.

From c8a9f8056f40f6201b84fdddb49a1c62630902c5 Mon Sep 17 00:00:00 2001
From: Jonathan Cameron <jic23@cam.ac.uk>

Subject: staging:iio:treewide only use shared to decide on interfaces

Internally the fact that say scale is shared across channels is
actually of remarkably little interest.  Hence lets not store it.
Numerous devices have weird combinations of channels sharing
scale anyway so it is not as though this was really telling
us much. Note however that we do still use the shared sysfs
attrs thus massively reducing the number of attrs in complex
drivers.

Side effect is that certain drivers that were abusing this
(mostly my work) needed to do a few more checks on what the
channel they are being queried on actually is.

This is also helpful for in kernel interfaces where we
just want to query the scale and don't care whether it
is shared with other channels or not.

regulator_get_voltage() returns an int so "scale_uv" should be an
int.  Making it unsigned here breaks the error handling.

Subject: staging:iio: Make write_event_value callback optional

Some devices have fixed thresholds which can not be modified so make the
write_event_value callback optional, so the drivers for these devices do not
have to implement a boilerplate no-op callback.

Subject: staging:iio: IIO_EVENT_CODE: Clamp channel numbers

Make sure we only use the allotted space for channel numbers in the event mask
and do not let them override other fields.

Since negative values are valid channel number, cast the channel number to
signed when extracting it from an event mask.

Commit e6477000fc ("staging:iio:dummy Add event support + fake event

is no Kconfig symbol named IIO_SIMPLE_DUMMY_EVGEN. The select statement

Subject: staging:iio: Add missing MODULE_DEVICE_TABLE and MODULE_ALIAS

Quite a few iio drivers provide no MODULE_DEVICE_TABLE or MODULE_ALIAS or only
provide a MODULE_ALIAS while they have support for multiple device ids. This
prevents auto module loading from working correctly.

This patch fixes it by adding the missing MODULE_DEVICE_TABLEs and
MODULE_ALIAS'.

Subject: Staging: bcm: Fix information leak in ioctl:
 IOCTL_BCM_REGISTER_READ_PRIVATE, IOCTL_BCM_EEPROM_REGISTER_READ

This patch fixes an information leak in ioctl
IOCTL_BCM_REGISTER_READ_PRIVATE and
IOCTL_BCM_EEPROM_REGISTER_READ when determining
the number of bytes to copy to user space.  Function,
usb_control_msg, returns the correct number of
bytes from the hardware.  Instead of using
this value, we were using a value derived from
user space. In this case, this value could be more
than the hardware allocated.  Therefore, this
patch copies the proper number of bytes from
the hardware, and uses this value as the maximum
number of bytes for user space.

Subject: Staging: bcm: Clean up code in ioctl: IOCTL_BCM_EEPROM_REGISTER_READ

This patch verifies two conditions before executing
a kmalloc call. First, it checks to see that
IoBuffer.OutputLength is not greater than an
unsigned short. If so, an invalid value may be
returned. The second change is a check to make
sure IoBuffer.OutputLength is not equal to
zero. Which simply keeps this code inline with
the other ioctl, IOCTL_BCM_REGISTER_READ_PRIVATE.

If it is not held, that means this ioctl used incorrectly.
Therefore, we do not want to take the lock ourselves here.

Subject: Staging: bcm: Fix semaphore locking error when downloading firmware.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch releases semaphore locks when
an error occurrs while attempting to
download firmware for the bcm driver.
When downloading firmware for this driver,
a process is expected to call
the following ioctl's in this order:
(1)IOCTL_BCM_BUFFER_DOWNLOAD_START,
(2)IOCTL_BCM_BUFFER_DOWNLOAD, and (3)
IOCTL_BCM_BUFFER_DOWNLOAD_STOP.
Semaphore, “Adapter->fw_download_sema” is
expected to be acquired in the first ioctl,
IOCTL_BCM_BUFFER_DOWNLOAD_START, and it should
block until IOCTL_BCM_BUFFER_DOWNLOAD_STOP
is called.  In this case, if an error
occurred before STOP finished, the semaphore
"Adapter->fw_download_sema" was not being released.

If ibss_wlan is NULL, it is not correct to memcpy into its field.

The semantic match that finds this problem is as follows:

Subject: rtl8192e: Don't copy huge struct by value (and make it const).

rtllib_is_shortslot() takes one argument - a struct that's more than a
kilobyte large. It should take a pointer instead of copying such a
huge struct - and the argument might as well be declared 'const' now
that we are at it, since it is not modified. This patch makes these
changes.

Use kzalloc rather than kmalloc followed by memset with 0

This considers some simple cases that are common and easy to validate
Note in particular that there are no ...s in the rule, so all of the
matched code has to be contiguous

The semantic patch that makes this change is available

Contents of TODO file has become more of a feature wish-list rather than issues

The functions vme_add_bus() and vme_remove_bus() were only being used
in the vme_register_bridge() and vme_unregister_bridge() functions
respectively. This patch gets rid of them and moves their code to
vme_register_bridge() and vme_unregister_bridge().

This patch implements a driver for the GE PIO2 VME Parallel I/O Card.  This
card is a 6U VME Card, implementing 32 solid-state relay switched IO lines,
in 4 groups of 8. Each bank of IO lines is built to function as input,
output or both depending on the variant of the card.

Subject: Staging: delete spectra driver

To quote Alan:
	Moorestown/Oaktrail has appeared only in the PC like form so the
	following bits of staging can be binned:

	drivers/staging/spectra

so let's delete it.

-This is a driver for NAND controller of Intel Moorestown platform.
-
-This driver is a standalone linux block device driver, it acts as if it's a normal hard disk.
-It includes three layer:
-	block layer interface - file ffsport.c
-	Flash Translation Layer (FTL) - file flash.c (implement the NAND flash Translation Layer, includs address mapping, garbage collection, wear-leveling and so on)
-	Low level layer - file lld_nand.c/lld_cdma.c/lld_emu.c (which implements actual controller hardware registers access)
-
-This driver can be build as modules or build-in.
-
-Dependency:
-This driver has dependency on IA Firmware of Intel Moorestown platform.
-It need the IA Firmware to create the block table for the first time.
-And to validate this driver code without IA Firmware, you can change the
-macro AUTO_FORMAT_FLASH from 0 to 1 in file spectraswconfig.h. Thus the
-driver will erase the whole nand flash and create a new block table.
-
-TODO:
-	- Enable Command DMA feature support
-	- lower the memory footprint
-	- Remove most of the unnecessary global variables
-	- Change all the upcase variable / functions name to lowercase
-	- Some other misc bugs
-
-Please send patches to:
-	Greg Kroah-Hartman <gregkh@suse.de>

From cd5351f4d2b1b884d8c21a7636d5c0ea3b69d123 Mon Sep 17 00:00:00 2001

Subject: staging: add omapdrm DRM/KMS driver for TI OMAP platforms

A DRM display driver for TI OMAP platform.  Similar to omapfb (fbdev)
and omap_vout (v4l2 display) drivers in the past, this driver uses the
DSS2 driver to access the display hardware, including support for
HDMI, DVI, and various types of LCD panels.  And it implements GEM
support for buffer allocation (for KMS as well as offscreen buffers
used by the xf86-video-omap userspace xorg driver).

The driver maps CRTCs to overlays, encoders to overlay-managers, and
connectors to dssdev's.  Note that this arrangement might change slightly
when support for drm_plane overlays is added.

For GEM support, non-scanout buffers are using the shmem backed pages
provided by GEM core (In drm_gem_object_init()).  In the case of scanout
buffers, which need to be physically contiguous, those are allocated
with CMA and use drm_gem_private_object_init().

See userspace xorg driver:
git://github.com/robclark/xf86-video-omap.git

Refer to this link for CMA (Continuous Memory Allocator):
http://lkml.org/lkml/2011/8/19/302

Links to previous versions of the patch:
v1: http://lwn.net/Articles/458137/
v2: http://patches.linaro.org/4156/
v3: http://patches.linaro.org/4688/
v4: http://patches.linaro.org/4791/

History:

v5: move headers from include/drm at Greg KH's request, minor rebasing
    on 3.2-rc1, pull in private copies of drm_gem_{get,put}_pages()
    because "drm/gem: add functions to get/put pages" patch is not
    merged yet
v4: bit of rework of encoder/connector _dpms() code, modeset_init()
    rework to not use nested functions, update TODO.txt
v3: minor cleanups, improved error handling for dev_load(), some minor
    API changes that will be needed later for tiled buffer support
v2: replace omap_vram with CMA for scanout buffer allocation, remove
    unneeded functions, use dma_addr_t for physical addresses, error
    handling cleanup, refactor attach/detach pages into common drm
    functions, split non-userspace-facing API into omap_priv.h, remove
    plugin API

v1: original

+TODO
+. check error handling/cleanup paths
+. add drm_plane / overlay support
+. add video decode/encode support (via syslink3 + codec-engine)
+. still some rough edges with flipping.. event back to userspace should
+  really come after VSYNC interrupt
+. where should we do eviction (detatch_pages())?  We aren't necessarily
+  accessing the pages via a GART, so maybe we need some other threshold
+  to put a cap on the # of pages that can be pin'd.  (It is mostly only
+  of interest in case you have a swap partition/file.. which a lot of
+  these devices do not.. but it doesn't hurt for the driver to do the
+  right thing anyways.)
+  . Use mm_shrinker to trigger unpinning pages.  Need to figure out how
+    to handle next issue first (I think?)
+  . Note TTM already has some mm_shrinker stuff..  maybe an argument to
+    move to TTM?  Or maybe something that could be factored out in common?
+. GEM/shmem backed pages can have existing mappings (kernel linear map,
+  etc..), which isn't really ideal.
+. Revisit GEM sync object infrastructure.. TTM has some framework for this
+  already.  Possibly this could be refactored out and made more common?
+  There should be some way to do this with less wheel-reinvention.
+. Review DSS vs KMS mismatches.  The omap_dss_device is sort of part encoder,
+  part connector.  Which results in a bit of duct tape to fwd calls from
+  encoder to connector.  Possibly this could be done a bit better.

Subject: staging/xgifb: Convert pci_table entries to PCI_DEVICE (if PCI_ANY_ID
 is used)

This patch converts pci_table entries to use the PCI_DEVICE macro,
if .subvendor and .subdevice are set to PCI_ANY_ID,
and thus improves readability.

v2:
Since the driver_data field isn't used anywhere we can also drop the
assignments for class, class_mask and driver_data.

Subject: staging: xgifb: delete XGI_GetSenseStatus()

Delete unused function XGI_GetSenseStatus().

Static functions XGINew_Is301B(), XGINew_Sense(), XGINew_GetPanelID(),
XGINew_BridgeIsEnable() and XGINew_SenseHiTV() can be deleted as well,
since they are not used anymore.

Subject: staging: tidspbridge: request dmtimer clocks on init

Given that dm timer framework doesn't support request of clocks
by soft | hard irqs because some recent changes, tidspbridge needs
to request its clocks on init and enable/disable them on demand.

This was first seen on 3.2-rc1.

Subject: staging/comedi/addi: Convert pci_table entries to PCI_DEVICE (if
 PCI_ANY_ID is used)

This patch converts pci_table entries to use the PCI_DEVICE macro,
if .subvendor and .subdevice are set to PCI_ANY_ID,
and thus improves readablity.

Since the driver_data field isn't used anywhere we can also drop the
assignments for class, class_mask and driver_data.

Moreover the hardcoded 0x15B8 was replaced by the more readable
PCI_VENDOR_ID_ADDIDATA

This patch converts pci_table entries to use the PCI_DEVICE macro,

and thus improves readablity.

Since the driver_data field isn't used anywhere we can also drop the
assignments for class, class_mask and driver_data.

This patch converts pci_table entries to use the PCI_DEVICE macro,
if .subvendor and .subdevice are set to PCI_ANY_ID,
and thus improves readablity.

Since the driver_data field isn't used anywhere we can also drop the
assignments for class, class_mask and driver_data.

This patch converts pci_table entries to use the PCI_DEVICE macro,

Since the driver_data field isn't used anywhere we can also drop the

Subject: staging:iio: filter description - low pass 3db frequency.

Introduce the first data filtering related parameter.
For now we are ignoring the filter type and merely specifying its
approximate (I read them off tiny graphs) 3db point.

This patch converts pci_table entries to use the PCI_DEVICE macro,
if .subvendor and .subdevice are set to PCI_ANY_ID,
and thus improves readablity.

Since CH_Agere_Systems_Mini_PCI_V1 is defined as 0 in hermes_pci_versions
and neither the enum nor the value is used anywhere else, we can drop
the assignment of .driver_data as it is initialized as 0 by default.

Subject: staging: xgifb: vb_setmode: make XGI_GetLVDSOEMTableIndex() static

XGI_GetLVDSOEMTableIndex() can be made static. Move the function, so that
forward declaration is not needed.

Subject: staging/mei: remove BUG_ON for testing of the response buffer size
 overflow

We can remove BUG_ON in mei_irq_thread_read_client_message()
as the testing for response buffer size overflow has already
graceful handling in place.

Subject: staging/mei: don't check if list is empty before looping

1. No need to check if a list is empty before list_for_each_ looping as
this is already checked by loop stopping conditional.

The side effect is reduced indentation depth
from:
	if (!list_empty)
		list_for_each()
to:
	list_for_each()

2. drop cb_ prefix from cl_pos, cl_next variables used in list_for_each
loops. The code is more compact and readable

From 763be8c0a919015a3c1e205005176d4aacec22e3 Mon Sep 17 00:00:00 2001
From: Mathieu Desnoyers <mathieu.desnoyers@efficios.com>
Date: Mon, 28 Nov 2011 07:42:15 -0500
Subject: lttng instrumentation: tracepoint events

Modifications to the in-kernel TRACE_EVENT are needed to generate the
compact event descriptions and the probe code LTTng generates. These
changes could apply to upstream TRACE_EVENT, but requires changing the
in-kernel API.

+LTTng system call tracing
+
+1) lttng-syscall-extractor
+
+You need to build a kernel with CONFIG_FTRACE_SYSCALLS=y and
+CONFIG_KALLSYMS_ALL=y for extraction. Apply the linker patch to get your
+kernel to keep the system call metadata after boot.  Then build and load
+the LTTng syscall extractor module. The module will fail to load (this
+is expected). See the dmesg output for system call metadata.
+
+2) Generate system call TRACE_EVENT().
+
+Take the dmesg metadata and feed it to lttng-syscalls-generate-headers.sh, e.g.,
+from the instrumentation/syscalls directory. See the script header for
+usage example.
+
+After these are created, we just need to follow the new system call additions,
+no need to regenerate the whole thing, since system calls are only appended to.

Subject: lttng: debugfs and procfs ABI

Add the "lttng" virtual file to debugfs and procfs. All operations are
performed through ioctls (LTTng ioctl range is already reserved
upstream) on this virtual file and on anonymous file descriptors
returned by these ioctls. Each file descriptor is associated with a
tracer "object" (session, channel, stream, event, context).

+LTTng 2.0 modules
+
+Mathieu Desnoyers
+November 1st, 2011
+
+LTTng 2.0 kernel modules is currently part of the Linux kernel staging
+tree. It features (new features since LTTng 0.x):
+
+- Produces CTF (Common Trace Format) natively,
+  (http://www.efficios.com/ctf)
+- Tracepoints, Function tracer, CPU Performance Monitoring Unit (PMU)
+  counters, kprobes, and kretprobes support,
+- Integrated interface for both kernel and userspace tracing,
+- Have the ability to attach "context" information to events in the
+  trace (e.g. any PMU counter, pid, ppid, tid, comm name, etc).
+  All the extra information fields to be collected with events are
+  optional, specified on a per-tracing-session basis (except for
+  timestamp and event id, which are mandatory).
+
+To build and install, you need to select "Staging" modules, and the
+LTTng kernel tracer.
+
+Use lttng-tools to control the tracer. LTTng tools should automatically
+load the kernel modules when needed. Use Babeltrace to print traces as a
+human-readable text log. These tools are available at the following URL:
+http://lttng.org/lttng2.0
+
+Please note that the LTTng-UST 2.0 (user-space tracing counterpart of
+LTTng 2.0) is now ready to be used, but still only available from the
+git repository.
+
+So far, it has been tested on vanilla Linux kernels 2.6.38, 2.6.39 and
+3.0 (on x86 32/64-bit, and powerpc 32-bit at the moment, build tested on
+ARM). It should work fine with newer kernels and other architectures,
+but expect build issues with kernels older than 2.6.36. The clock source
+currently used is the standard gettimeofday (slower, less scalable and
+less precise than the LTTng 0.x clocks).  Support for LTTng 0.x clocks
+will be added back soon into LTTng 2.0.  Please note that lttng-modules
+2.0 can build on a Linux kernel patched with the LTTng 0.x patchset, but
+the lttng-modules 2.0 replace the lttng-modules 0.x, so both tracers
+cannot be installed at the same time for a given kernel version.
+
+* Note about Perf PMU counters support
+
+Each PMU counter has its zero value set when it is attached to a context with
+add-context. Therefore, it is normal that the same counters attached to both the
+stream context and event context show different values for a given event; what
+matters is that they increment at the same rate.

+Please contact Mathieu Desnoyers <mathieu.desnoyers@efficios.com> for
+questions about this TODO list. The "Cleanup/Testing" section would be
+good to go through before integration into mainline. The "Features"
+section is a wish list of features to complete before releasing the
+"LTTng 2.0" final version, but are not required to have LTTng working.
+These features are mostly performance enhancements and instrumentation
+enhancements.
+
+TODO:
+
+A) Cleanup/Testing
+
+	1) Remove debugfs "lttng" file (keep only procfs "lttng" file).
+	   The rationale for this is that this file is needed for
+	   user-level tracing support (LTTng-UST 2.0) intended to be
+	   used on production system, and therefore should be present as
+	   part of a "usually mounted" filesystem rather than a debug
+	   filesystem.
+
+	2) Cleanup wrappers. The drivers/staging/lttng/wrapper directory
+	   contains various wrapper headers that use kallsyms lookups to
+	   work around some missing EXPORT_SYMBOL_GPL() in the mainline
+	   kernel. Ideally, those few symbols should become exported to
+	   modules by the kernel.
+
+	3) Test lib ring buffer snapshot feature.
+	   When working on the lttngtop project, Julien Desfossez
+	   reported that he needed to push the consumer position
+	   forward explicitely with lib_ring_buffer_put_next_subbuf.
+	   This means that although the usual case of pairs of
+	   lib_ring_buffer_get_next_subbuf/lib_ring_buffer_put_next_subbuf
+	   work fine, there is probably a problem that needs to be
+	   investigated in
+	   lib_ring_buffer_get_subbuf/lib_ring_buffer_put_subbuf, which
+	   depend on the producer to push the reader position.
+	   Contact: Julien Desfossez <julien.desfossez@polymtl.ca>
+
+	4) Test latest -rt kernel support.
+	   There has been report of corrupted traces when tracing a
+	   3.0.10-rt27 in the area of access_ok() system call event.
+	   Still has to be investigated. Cannot be reproduced with
+	   mainline kernel.
+	   Contact: Yannick Brosseau <yannick.brosseau@polymtl.ca>
+
+B) Features
+
+	1) Integration of the LTTng 0.x trace clocks into
+	   LTTng 2.0.
+	     Currently using mainline kernel monotonic clock. NMIs can
+	     therefore not be traced, and this causes a significant
+	     performance degradation compared to the LTTng 0.x trace
+	     clocks. Imply the creation of drivers/staging/lttng/arch to
+	     contain the arch-specific clock support files.
+	     * Dependency: addition of clock descriptions to CTF.
+	   See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
+	        for the LTTng 0.x git tree.
+
+	2) Port OMAP3 LTTng trace clocks to x86 to support systems
+	   without constant TSC.
+	    * Dependency: (B.1)
+	   See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
+	        for the LTTng 0.x git tree.
+
+	3) Implement mmap operation on an anonymous file created by a
+	   LTTNG_KERNEL_CLOCK ioctl to export data to export
+	   synchronized kernel and user-level LTTng trace clocks:
+	   with:
+	      - shared per-cpu data,
+	      - read seqlock.
+	   The content exported by this shared memory area will be
+	   arch-specific.
+	   * Dependency: (B.1) && (B.2)
+	   See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
+	        for the LTTng 0.x git tree, which has vDSO support for
+	        LTTng trace clock on the x86 architecture.
+
+	3) Integrate the "statedump" module from LTTng 0.x into LTTng
+	   2.0.
+	     * Dependency: addition of "dynamic enumerations" type to CTF.
+	   See: http://git.lttng.org/?p=lttng-modules.git;a=shortlog;h=refs/heads/v0.19-stable
+	        ltt-statedump.c
+
+	4) Generate system call TRACE_EVENT headers for all
+	   architectures (currently done: x86 32/64).
+
+	5) Define "unknown" system calls into instrumentation/syscalls
+	   override files / or do SYSCALL_DEFINE improvements to
+	   mainline kernel to allow automatic generation of these
+	   missing system call descriptions.
+
+	6) Create missing tracepoint event headers files into
+	   instrumentation/events from headers located in
+	   include/trace/events/. Choice: either do as currently done,
+	   and copy those headers locally into the lttng driver and
+	   perform the modifications locally, or push TRACE_EVENT API
+	   modification into mainline headers, which would require
+	   collaboration from Ftrace/Perf maintainers.
+
+	7) Poll: implement a poll and/or epoll exclusive wakeup scheme,
+	   which contradicts POSIX, but protect multiple consumer
+	   threads from thundering herd effect.
+
+	8) Re-integrate sample modules from libringbuffer into
+	   lttng driver. Those modules can be used as example of how to
+	   use libringbuffer in other contexts than LTTng, and are
+	   useful to perform benchmarks of the ringbuffer library.
+	   See: http://www.efficios.com/ringbuffer
+
+	9) NOHZ support for lib ring buffer. NOHZ infrastructure in the
+	   Linux kernel does not support notifiers chains, which does
+	   not let LTTng play nicely with low power consumption setups
+	   for flight recorder (overwrite mode) live traces. One way to
+	   allow integration between NOHZ and LTTng would be to add
+	   support for such notifiers into NOHZ kernel infrastructure.
+
+	10) Turn drivers/staging/lttng/ltt-probes.c probe_list into a
+	    hash table. Turns O(n^2) trace systems registration (cost
+	    for n systems) into O(n). (O(1) per system)
+
+	11) drivers/staging/lttng/probes/lttng-ftrace.c:
+	    LTTng currently uses kretprobes for per-function tracing,
+	    not the function tracer. So lttng-ftrace.c should be used
+	    for "all" function tracing.
+
+	12) drivers/staging/lttng/probes/lttng-types.c:
+	    This is a currently unused placeholder to export entire C
+	    type declarations into the trace metadata, e.g. for support
+	    of describing the layout of structures/enumeration mapping
+	    along with syscall entry events.  The design of this support
+	    will likely change though, and become integrated with the
+	    TRACE_EVENT support within lttng, by adding new macros, and
+	    support for generation of metadata from these macros, to
+	    allow description of those compound types/enumerations.
+

From 1e8ab70d74ed14bc287e2cb98145e860e2d95f6e Mon Sep 17 00:00:00 2001
From: Mathieu Desnoyers <mathieu.desnoyers@efficios.com>
Date: Mon, 28 Nov 2011 07:42:24 -0500
Subject: lttng: probe callbacks

Implement the LTTng probe callbacks. One notable file here is
lttng-events.h, which is the core implementation of the LTTng
TRACE_EVENT macros for generation of probes and tracepoint decription
from the TRACE_EVENT declarations.

+config LTTNG
+	tristate "LTTng kernel tracer"
+	depends on TRACEPOINTS
+	help
+	  The LTTng 2.0 Tracer Toolchain allows integrated kernel and
+	  user-space tracing from a single user interface: the "lttng"
+	  command. See http://lttng.org website for the "lttng-tools"
+	  user-space tracer control tools package and the "babeltrace"
+	  package for conversion of trace data to a human-readable
+	  format.
+
+	  LTTng features:
+	  - System-wide tracing across kernel, libraries and
+	    applications,
+	  - Tracepoints, detailed syscall tracing (fast strace replacement),
+	    Function tracer, CPU Performance Monitoring Unit (PMU) counters
+	    and kprobes support,
+	  - Have the ability to attach "context" information to events in the
+	    trace (e.g. any PMU counter, pid, ppid, tid, comm name, etc). All
+	    the extra information fields to be collected with events are
+	    optional, specified on a per-tracing-session basis (except for
+	    timestamp and event id, which are mandatory).
+	  - Precise and fast clock sources with near cycle-level
+	    timestamps,
+	  - Efficient trace data transport:
+	    - Compact Binary format with CTF,
+	    - Per-core buffers ensures scalability,
+	    - Fast-paths in caller context, amortized synchronization,
+	    - Zero-copy using splice and mmap system calls, over disk,
+	      network or consumed in-place,
+	  - Multiple concurrent tracing sessions are supported,
+	  - Designed to meet hard real-time constraints,
+	  - Supports live streaming of the trace data,
+	  - Produces CTF (Common Trace Format) natively (see
+	    http://www.efficios.com/ctf).

Subject: Staging: bcm: Clean up patch that calls semaphore down_trylock
 directly.

This patch evaluates/calls the down_trylock locking
function directly, instead of storing the results
in a variable and evaluating the variable. These
changes were made in:
IOCTL_BCM_BUFFER_DOWNLOAD_STOP and
IOCTL_BCM_BUFFER_DOWNLOAD_START.

Subject: Staging: bcm: Alter code to move error handling closer to the calls.

This is a cleanup patch. I've shuffled the code around to
move the error handling closer to the calls. I've removed
some indent levels. I've replaced break statements with
direct returns.

Subject: Staging: bcm: Reverse semaphore locking in
 IOCTL_BCM_BUFFER_DOWNLOAD_STOP.

This patch reorders the semaphore locking.
It makes better sense to first evaluate
fw_download_sema semaphore then
NVMRdmWrmLocl semaphore. The
fw_download_sema is suppose to be
acquired in the START ioctl.  If this is
not true, then it does not make sense
to continue.

Subject: Staging: iio/accel: Changed data type in adis16220_write_16bit to u16

In the adis16220_write_16bit() function we used a long value to store
parsed data from the char* buffer buf.
The called function to actually write the data,
adis16220_spi_write_reg_16(), takes a u16 value as a parameter, so up
to now a value larger than u16 was silently ignored as it was only
truncated when passing the parameter.
Now this function will only accept values fitting into a u16.

Additionally the parsing function was changed to overcome the now
obsolete strict_strtol() function.

Subject: Staging: iio/accel: Changed data type for val to unsigned long in
 write_frequency

In lis3102dq_write_frequency() we used a long variable to store the
value parsed from the char* buffer buf, as there only was a
strict_strtol() function to parse values.
Now we have got kstrto* which allows us to convert to the right data
type in most cases.

In this particular function we want to write a frequency value, and it
doesn't make sense to allow negative values here (as Dan Carpenter
pointed out in a previous email).
This means we can now parse the value into an unsigned long and get an
error for invalid (e.g. negative) values.

Subject: Staging: iio/accel: Changed data type of val in
 store_measurement_mode to u8

The code in sca3000_store_measurement_mode() uses the variable val to
do bitwise operations with an int mask and or-s it into st->rx[0] which
is an entry in a u8 array (see sca3000.h).

This means up to now values larger than a u8 were silently ignored and
just the lower 8 bits counted into the value that was written into
st->rx[0]. This code will return -ERANGE if the value in buf was too
large to fit into a u8.

Subject: staging: iio: Use kcalloc instead of kzalloc to allocate array

The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.

The semantic patch that makes this change is available
in https://lkml.org/lkml/2011/11/25/107

Subject: Staging: iio/adc: strict_strtoul was used with a long type variable

The function ad7280_store_balance_timer() parses data from a char*
buffer into a long variable, but uses the the function strict_strtoul
which expects a pointer to an unsigned long variable as its third
parameter.

As Dan Carpenter mentioned, the values are capped a few lines later,
but a check if val is negative is missing.
Now this function will return -ERANGE if there is a representation of
a negative number in buf.

Additionally the checkpatch.pl considers strict_strtoul as obsolete.
I replaced its call with the suggested kstrtoul.

Subject: Staging: VME: PIO2: Correct irq reset

The loop used to reset the interrupt masks has faulty logic. There are 4
banks of 8 I/O, however each mask is comprised of 2 bits and thus there are
8 sets of registers to clear. Driver was wrongly equating this with 8 banks
leading to a us writing past the end of the "bank" array (used to store mask
configuration as these registers are write only) and thus causing memory
corruption. Clear both registers of masks for each bank and half iterations.

Subject: Staging: iio/accel: Changed return type of
 lis3l02dq_read_event_config() to int

The lis3l02dq_read_event_config() function returned an ssize_t up to
now, which lead to a compiler warning in line 660 (initialization from
incompatible pointer type). The iio_info struct is defined to accept an
int-returning function as the read_event_config parameter.

Also it seems odd to have the check for (ret < 0) and return ret in
this case, when the return type is signed.

Subject: rtl8192e: move RTL_DEBUG and proc prototypes

The RTL_DEBUG enum is used for rt_global_debug_component global
variable and RT_TRACE. It should be in rtl_debug.h and not rtl_core.h.

The rtl8192_proc_* functions are r8192 specific and should not be in
rtl_debug.h. Move them to rtl_core.h.

Subject: rtl8192e: create generic rtllib_debug.h

Rename rtl_debug.h to rtllib_debug.h. Source files should include
rtllib.h if they are generic and rtl_core.h if they are r8192e
specific. Files should never include both.

From 3b28499c5519e59fbe9c2dea49ece5a3665be787 Mon Sep 17 00:00:00 2001
From: Sean MacLennan <seanm@seanm.ca>
Date: Mon, 28 Nov 2011 20:20:26 -0500
Subject: rtl8192e: Export symbols

The rtl8192e driver had a natural split between the more generic
rtllib code and the more specific rtl8192e code. This patch exports
all the symbols needed by the r8192 specific code from the rtllib
generic code.

From d37e0208df563af9c6fada84e620aabed581b3a8 Mon Sep 17 00:00:00 2001
From: Sean MacLennan <seanm@seanm.ca>
Date: Mon, 28 Nov 2011 20:21:27 -0500
Subject: rtl8192e: Split the driver up

This patch splits the current r8192e_pci driver up into six different
drivers: rtllib, rtllib_crypt, rtllib_crypt_ccmp, rtllib_crypt_tkip,
rtllib_crypt_wep, and r8192e_pci.

Now that they are proper modules, the init and exit functions do not
need to be called directly. Also, the rtllib_*_null functions are not
needed since they will be loaded on demand.

From 3d461c912462b6b36ff9cf2c2f605ef37aeab438 Mon Sep 17 00:00:00 2001
From: Sean MacLennan <seanm@seanm.ca>

Subject: rtl8192e: Split into two directories

Now that the rtl8192e driver is split up, it makes sense to keep the
rtllib code in one directory and the rtl8192e specific code in
another. This patch contains the split and the fixup of includes.

Since rtl_core.h already included rtllib.h and dot11d.h, rtl_core.h
was updated to point to the parent directory. All other references to
rtllib.h and dot11d.h in the rtl8192e specific code where deleted
rather than fixed. This leaves just one file that needs to know the
real location of the rtllib includes.

From 355b0502f6efea0ff9492753888772c96972d2a3 Mon Sep 17 00:00:00 2001
From: Greg Kroah-Hartman <gregkh@suse.de>
Date: Wed, 30 Nov 2011 20:18:14 +0900
Subject: Revert "Staging: android: delete android drivers"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This reverts commit b0a0ccfad85b3657fe999805df65f5cfe634ab8a.

Turns out I was wrong, we want these in the tree.

Note, I've disabled the drivers from the build at the moment, so other
patches can be applied to fix some build issues due to internal api
changes since the code was removed from the tree.

+ * The lowmemorykiller driver lets user-space specify a set of memory thresholds
+ * where processes with a range of oom_adj values will get killed. Specify the
+ * minimum oom_adj values in /sys/module/lowmemorykiller/parameters/adj and the
+ * number of free pages in /sys/module/lowmemorykiller/parameters/minfree. Both
+ * files take a comma separated list of numbers in ascending order.
+ *
+ * For example, write "0,8" to /sys/module/lowmemorykiller/parameters/adj and
+ * "1024,4096" to /sys/module/lowmemorykiller/parameters/minfree to kill processes
+ * with a oom_adj value of 8 or higher when the free memory drops below 4096 pages
+ * and kill processes with a oom_adj value of 0 or higher when the free memory
+ * drops below 1024 pages.
+ *
+ * The driver considers memory used for caches to be free, but if a large
+ * percentage of the cached memory is locked this can be very inaccurate
+ * and processes may not get killed until the normal oom killer is triggered.

 cluttered by apanic threads

[Note, this is part of a patch from Sam, just the drivers/staging/
portion, that adds a function that the apanic code calls, but the apanic
code isn't here, so just include part of this to make merges and diffs
easier and this keeps things self-contained - gregkh]

Subject: staging: android: lowmemorykiller: Don't try to kill the same pid
 over and over

  Under certain circumstances, a process can take awhile to
handle a sig-kill (especially if it's in a scheduler group with
a very low share ratio). When this occurs, lowmemkiller returns
to vmscan indicating the process memory has been freed - even
though the process is still waiting to die. Since the memory
hasn't actually freed, lowmemkiller is called again shortly after,
and picks the same process to die; regardless of the fact that
it has already been 'scheduled' to die and the memory has already
been reported to vmscan as having been freed.

  Solution is to check fatal_signal_pending() on the selected
task, and if it's already pending destruction return; indicating
to vmscan that no resources were freed on this pass.

Subject: staging: android: lowmemkiller: Substantially reduce overhead during
 reclaim

This patch optimizes lowmemkiller to not do any work when it has an outstanding
kill-request. This greatly reduces the pressure on the task_list lock
(improving interactivity), as well as improving the vmscan performance
when under heavy memory pressure (by up to 20x in tests).

Note: For this enhancement to work, you need CONFIG_PROFILING

Subject: staging: binder: Fix memory corruption via page aliasing

binder_deferred_release was not unmapping the page from the buffer
before freeing it, causing memory corruption.  This only happened
when page(s) had not been freed by binder_update_page_range, which
properly unmaps the pages.

This only happens on architectures with VIPT aliasing.

To reproduce, create a program which opens, mmaps, munmaps, then closes
the binder very quickly.  This should leave a page allocated when the
binder is released.  When binder_deferrred_release is called on the
close, the page will remain mapped to the address in the linear
proc->buffer.  Later, we may map the same physical page to a different
virtual address that has different coloring, and this may cause
aliasing to occur.

PAGE_POISONING will greatly increase your chances of noticing any
problems.

Subject: rtl8192e: Rename clashing symbols

The "rtl8192e: Export symbols" patch exported three functions already
exported by the rtl8192u driver. This patch renames the three functions:
  Dot11d_Init => dot11d_init
  HTUpdateSelfAndPeerSetting => HT_update_self_and_peer_setting
  IsLegalChannel => rtllib_legal_channel

This check is performed at mapping setup time in
lib_ring_buffer_mmap_buf() already, so we can safely remove this
duplicata.

Let's move the NULL buf check to the file "open", where it belongs. The
"open" file operation is the actual interface between lib ring buffer
and the modules using it.

bool :1, uchar :1 or uint :1 could make sense. uchar:1/bool:1 won't save
any space here, because the surrounding fields are either uint or
pointers, so alignment will just add padding.

I try to use int/uint whenever possible because x86 CPUs tend to get
less register false-dependencies when using instructions modifying the
whole register (generated by using int/uint types) rather than only part
of it (uchar/char/bool). I only use char/uchar/bool when there is a
clear wanted space gain.

The reason why I never use the bool type within a structure when I want
a compact representation is that bool takes a whole byte just to
represent one bit:

struct usebitfield {
    int a;
    unsigned int f:1, g:1, h:1, i:1, j:1;
    int b;
};

struct usebool {
    int a;
    bool f, g, h, i, j;
    int b;
};

struct useboolbf {
    int a;
    bool f:1, g:1, h:1, i:1, j:1;
    int b;
};

int main()
{
    printf("bitfield %d bytes, bool %d bytes, boolbitfield %d bytes\n",
            sizeof(struct usebitfield), sizeof(struct usebool),
            sizeof(struct useboolbf));
}

result:

bitfield 12 bytes, bool 16 bytes, boolbitfield 12 bytes

This is because each bool takes one byte, while the bitfields are put in
units of "unsigned int" (or bool for the 3rd struct). So in this
example, we need 5 bytes + 3 bytes alignment for the bool, but only 4
bytes to hold the "unsigned int" unit for the bitfields.

The choice between bool and bitfields must also take into account the
frequency of access to the variable, because bitfields require mask
operations to access the selected bit(s). You will notice that none of
these bitfields are accessed on the tracing fast-path: only in
slow-paths. Therefore, space gain is more important than speed here.

One might argue that I have so few of these fields here that it does not
make an actual difference to go for bitfield or bool. I am just trying
to choose types best suited for their intended purpose, ensuring they
are future-proof and will allow simply adding more fields using the same
type, as needed.

So I guess I'll go for uint :1.

"line6" hasn't been set at this point and we should be using

Gcc would have complained about this if it weren't for the fact that we
initialized line6 to NULL.  I removed the initialization.

Subject: Staging: hv: storvsc: Disable clustering

Disable clustering, since the host side on Hyper-V requires that
each I/O element not exceed the page size. As part of this
cleanup, get rid of the function to merge bvecs, as the primary
reason for this function was to avoid having an element exceed
the page size.

Subject: Staging: hv: storvsc: Implement per device memory pools

The current code implemented a per-HBA memory pool mechanism. For IDE disks
managed by this driver, there is a one to one correspondance between the
block device and the associated virtual HBA and since currently only IDE devices
can be the boot device, this addressed the deadlock issues that were raised during
the review process. This patch implements a per-lun memory pool mechanism.

Subject: Staging: iio/accel: Changed data type of mask in
 store_measurement_mode() to u8

In sca3000_store_measurement_mode() we parse a value from a string
buffer via kstrtou8, and store the parsed value into a u8 after
and-ing it with mask.

As we are only interested in the lowest two bits here and mask is
initialized with a fixed value 0x03, mask may as well be a u8.

Subject: Staging: iio/accel: Added a range check for val in
 store_measurement_mode()

In sca3000_store_measurement_mode() we use val to and it with a mask.
This mask is only two bits long (as we are only interested in the
lowest two bits), so a value bigger than 3 was silently ignored so
far.

Now this function will return -EINVAL, if val is bigger than 3.

When illuminance0_calibbias gets 4000 (for a 4x multiplier), we see lux
granularity of 4.  Reversing the order of the right shift and multiplication
retains the precision of the unadjusted lux value.

Subject: staging:iio: Remove redundant spi driver bus initialization

In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_register_driver() so
we can drop the manual assignment.

The patch was generated using the following coccinelle semantic patch:
// <smpl>
@@
identifier _driver;
@@
 struct spi_driver _driver = {
 	.driver = {
-		.bus = &spi_bus_type,
 	},
 };
// </smpl>

Subject: staging:iio: add demux optionally to path from device to buffer

This gives you only what you ask for which is handy
for some devices with weird scan combinations.

Routes all data flow through a core utility function.
That and this demuxing support will be needed to do
demuxing to multiple destinations in kernel.

Date: Mon, 5 Dec 2011 22:18:13 +0000
Subject: staging:iio: remove userspace access to bytes per datum.

There are no known reasons why userspace should want this value.
It can be established from the buffer description anyway.

From 550268ca1111a5b4737f15f7bf646cede9d1f0cd Mon Sep 17 00:00:00 2001
From: Jonathan Cameron <jic23@cam.ac.uk>
Date: Mon, 5 Dec 2011 22:18:15 +0000
Subject: staging:iio: scrap scan_count and ensure all drivers use
 active_scan_mask

Obviously drivers should only use this for pushing to buffers.
They need buffer->scan_mask for pulling from them post demux.

Subject: staging:iio: Fix sw_ring memory corruption

The sw_ring does not properly handle the case where the write pointer already
has wrapped around, the read pointer has not and the remaining buffer space at
the end is enough to fill the read buffer:

  +-----------------------------------+
  |     |              |##data##|     |
  +-----------------------------------+
     write_p        read_p

In this case the current code will copy all available data to the buffer and
as a result will write beyond the bounds of the buffer and cause a memory
corruption.

To address this issue this patch adds code to calculate the available buffer
space and makes sure that the number of bytes to copy does not exceed this
number. This allows the code which copies the data around to be simplified as
it only has to consider two cases: Read wraps around and read does not wrap
around.

Subject: staging:iio: Fix scan mask update

When updating the scan mask we have to check the actual scan mask for if the
channel is already enabled, not the matching scan mask from the available
scan masks. The bit will already be set there and as a result the actual
scan mask will not get updated and the channel stays disabled.

Also fix the return value of iio_scan_el_store which would return 1 instead of
the number of bytes written if the channel was already active in the scan mask.

XG27 has the second display output already hardcoded to disabled. Just
in case, ensure that it has the LVDS code paths disabled. This will
simplify the future cleanups.

Subject: Staging: bcm: Fix double free of 'pReadData' in IOCTL_BCM_NVM_WRITE.

This patch fixes a memory error in ioctl,
IOCTL_BCM_NVM_WRITE. While copying data to
user space, if an error occurs, pReadData
is freed. Then, at the end of the ioctl,
pReadData was being freed again.

Subject: Staging: bcm: Alter code to move error handling closer to the calls;
 and remove white space, IOCTL_BCM_NVM_WRITE.

This is a clean up patch for IOCTL_BCM_NVM_WRITE
that replaces the assignment of the Status
variable with direct returns of the error code,
replaces the break statements with direct returns,
and removes a white space.

Subject: Staging: bcm: Alter return value for copy_to/from_user() to "return

In this clean up patch, I altered functions: copy_to/
from_user() to return -EFAULT when an error occurs.
I also replaced break statements when an error occurs
from copy_to/from_user() with direct returns of -EFAULT.

Subject: Staging: hv: storvsc: Fix a bug in create_bounce_buffer()

Set the length field of the scatter gather elements correctly when we create
the bounce buffer. When we use the bounce buffer for a "write" operation,
the act of copying to the bounce buffer, correctly deals with this issue.
However, on the "read" side, the current code was not correctly setting
the buffer length. Fix this bug. Note that when we copy from the bounce
buffer (for the read case), the amount we copy is controlled by the original
scatter gather list given to the driver.

Subject: Staging: zram: Add a missing GFP_KERNEL specifier in
 zram_init_device()

The allocation of zram->compress_buffer is misssing a GFP_* specifier.
This is equivalent to GFP_NOWAIT but it is more likely a omission.
Since the allocation just above it uses GFP_KERNEL, there is no reason
to use GFP_NOWAIT here. Therefore, add GFP_KERNEL.

Subject: staging/mei: fix failure for multiple mei clients connection

The irq handler processes queued mei clients connect requests, which were
not transferred to the device in ioctl context due to unavailability
of the write buffer.

The handler may transfer the connection request only if there is
no other ongoing  requests for the same mei id.
This condition was implemented inversely which depending on
the write buffer availability lead to seemingly random
failures during connection attempts.

 Intel AMT OS Health Watchdog:
 =============================
 The Intel AMT Watchdog is an OS Health (Hang/Crash) watchdog.
 Whenever the OS hangs or crashes, Intel AMT will send an event
-to whoever subscribed to this event. This mechanism means that
-IT knows when a platform crashes even when there is a hard failure
-on the host.
-The AMT Watchdog is composed of two parts:
-	1) FW Feature - that receives the heartbeats
-	   and sends an event when the heartbeats stop.
-	2) MEI driver – connects to the watchdog (WD) feature,
-	   configures the watchdog and sends the heartbeats.
-
-The MEI driver configures the Watchdog to expire by default
-every 120sec unless set by the user using module parameters.
-The Driver then sends heartbeats every 2sec.
+to any subsciber to this event. This mechanism means that
+IT knows when a platform crashes even when there is a hard failureon the host.
 
-If WD feature does not exist (i.e. the connection failed),
-the MEI driver will disable the sending of heartbeats.
+The Intel AMT Watchdog is composed of two parts:
+	1) Firmware feature - receives the heartbeats
+	   and sends an event when the heartbeats stop.
+	2) Intel MEI driver - connects to the watchdog feature, configures the
+	   watchdog and sends the heartbeats.
 
-Module Parameters
-=================
-watchdog_timeout - the user can use this module parameter
-to change the watchdog timeout setting.
+The Intel MEI driver uses the kernel watchdog to configure the Intel AMT
+Watchdog and to send heartbeats to it. The default timeout of the
+watchdog is 120 seconds.
 
-This value sets the Intel AMT watchdog timeout interval in seconds;
-the default value is 120sec.
-in order to disable the watchdog activites set the value to 0.
-Normal values should be between 120 and 65535
+If the Intel AMT Watchdog feature does not exist (i.e. the connection failed),
+the Intel MEI driver will disable the sending of heartbeats.

Subject: staging: et131x: Revert changes from previous commit

In commit 834d0ee317b (uintxy_t removal) not all changes were trival text replacements, some converted u64 -> dma_addr_t.
In some configurations dma_addr_t is a u32, meaning that some bit operations cause build warnings. From Randy Dunlap:

----------------
on i386 (X86_32) builds:

drivers/staging/et131x/et131x.c:2483:8: warning: right shift count >= width of type
drivers/staging/et131x/et131x.c:2531:8: warning: right shift count >= width of type
----------------

Removed these by reverting dma_addr_t back to u64 types, as well as
reverting some other non-trivial changes from the aforementioned commit.

From: Andy Gross <andy.gross@ti.com>

Subject: drm/omap: DMM/TILER support for OMAP4+ platform

Dynamic Memory Manager (DMM) is a hardware block in the OMAP4+
processor that contains at least one TILER instance.  TILER, or
Tiling and Isometric Lightweight Engine for Rotation, provides
IOMMU capabilities through the use of a physical address translation
table.  The TILER also provides zero cost rotation and mirroring.

The TILER provides both 1D and 2D access by providing different views
or address ranges that can be used to access the physical memory that
has been mapped in through the PAT.  Access to the 1D view results in
linear access to the underlying memory.  Access to the 2D views result
in tiled access to the underlying memory resulted in increased
efficiency.

The TILER address space is managed by a tiler container manager (TCM)
and allocates the address space through the use of the Simple Tiler
Allocation algorithm (SiTA).  The purpose of the algorithm is to keep
fragmentation of the address space as low as possible.

Subject: drm/omap: add GEM support for tiled/dmm buffers

TILER/DMM provides two features for omapdrm GEM objects:
1) providing a physically contiguous view to discontiguous memory
   for hw initiators that cannot otherwise support discontiguous
   buffers (DSS scanout, IVAHD video decode/encode, etc)
2) providing untiling for 2d tiled buffers, which are used in some
   cases to provide rotation and reduce memory bandwidth for hw
   initiators that tend to access data in 2d block patterns.

For 2d tiled buffers, there are some additional complications when
it comes to userspace mmap'ings.  For non-tiled buffers, the original
(potentially physically discontiguous) pages are used to back the
mmap.  For tiled buffers, we need to mmap via the tiler/dmm region to
provide an unswizzled view of the buffer.  But (a) the buffer is not
necessarily pinned in TILER all the time (it can be unmapped when
there is no DMA access to the buffer), and (b) when they are they
are pinned, they not necessarily page aligned from the perspective of
the CPU.  And non-page aligned userspace buffer mapping is evil.

To solve this, we reserve one or more small regions in each of the 2d
containers when the driver is loaded to use as a "user-GART" where we
can create a second page-aligned mapping of parts of the buffer being
accessed from userspace.  Page faulting is used to evict and remap
different regions of whichever buffers are being accessed from user-
space.

 . Review DSS vs KMS mismatches.  The omap_dss_device is sort of part encoder,

   encoder to connector.  Possibly this could be done a bit better.

Include: a fix for a recently introduced change: obviously max_t should
be used instead of min_t here. Also, a likely should apply to the result
of the comparison, not the variable per se.

Subject: Staging: lttng: remove from the drivers/staging/ tree

The "proper" way to do this is to work with the existing in-kernel
tracing subsystem and work to get the missing features that are in lttng
into those subsystems.

-config LTTNG
-	tristate "LTTng kernel tracer"
-	depends on TRACEPOINTS
-	help
-	  The LTTng 2.0 Tracer Toolchain allows integrated kernel and
-	  user-space tracing from a single user interface: the "lttng"
-	  command. See http://lttng.org website for the "lttng-tools"
-	  user-space tracer control tools package and the "babeltrace"
-	  package for conversion of trace data to a human-readable
-	  format.
-
-	  LTTng features:
-	  - System-wide tracing across kernel, libraries and
-	    applications,
-	  - Tracepoints, detailed syscall tracing (fast strace replacement),
-	    Function tracer, CPU Performance Monitoring Unit (PMU) counters
-	    and kprobes support,
-	  - Have the ability to attach "context" information to events in the
-	    trace (e.g. any PMU counter, pid, ppid, tid, comm name, etc). All
-	    the extra information fields to be collected with events are
-	    optional, specified on a per-tracing-session basis (except for
-	    timestamp and event id, which are mandatory).
-	  - Precise and fast clock sources with near cycle-level
-	    timestamps,
-	  - Efficient trace data transport:
-	    - Compact Binary format with CTF,
-	    - Per-core buffers ensures scalability,
-	    - Fast-paths in caller context, amortized synchronization,
-	    - Zero-copy using splice and mmap system calls, over disk,
-	      network or consumed in-place,
-	  - Multiple concurrent tracing sessions are supported,
-	  - Designed to meet hard real-time constraints,
-	  - Supports live streaming of the trace data,
-	  - Produces CTF (Common Trace Format) natively (see
-	    http://www.efficios.com/ctf).

-
-Mathieu Desnoyers
-November 1st, 2011
-
-LTTng 2.0 kernel modules is currently part of the Linux kernel staging
-tree. It features (new features since LTTng 0.x):
-
-- Produces CTF (Common Trace Format) natively,
-  (http://www.efficios.com/ctf)
-- Tracepoints, Function tracer, CPU Performance Monitoring Unit (PMU)
-  counters, kprobes, and kretprobes support,
-- Integrated interface for both kernel and userspace tracing,
-- Have the ability to attach "context" information to events in the
-  trace (e.g. any PMU counter, pid, ppid, tid, comm name, etc).
-  All the extra information fields to be collected with events are
-  optional, specified on a per-tracing-session basis (except for
-  timestamp and event id, which are mandatory).
-
-To build and install, you need to select "Staging" modules, and the
-LTTng kernel tracer.
-
-Use lttng-tools to control the tracer. LTTng tools should automatically
-load the kernel modules when needed. Use Babeltrace to print traces as a
-human-readable text log. These tools are available at the following URL:
-http://lttng.org/lttng2.0
-
-Please note that the LTTng-UST 2.0 (user-space tracing counterpart of
-LTTng 2.0) is now ready to be used, but still only available from the
-git repository.
-
-So far, it has been tested on vanilla Linux kernels 2.6.38, 2.6.39 and
-3.0 (on x86 32/64-bit, and powerpc 32-bit at the moment, build tested on
-ARM). It should work fine with newer kernels and other architectures,
-but expect build issues with kernels older than 2.6.36. The clock source
-currently used is the standard gettimeofday (slower, less scalable and
-less precise than the LTTng 0.x clocks).  Support for LTTng 0.x clocks
-will be added back soon into LTTng 2.0.  Please note that lttng-modules
-2.0 can build on a Linux kernel patched with the LTTng 0.x patchset, but
-the lttng-modules 2.0 replace the lttng-modules 0.x, so both tracers
-cannot be installed at the same time for a given kernel version.
-
-* Note about Perf PMU counters support
-
-Each PMU counter has its zero value set when it is attached to a context with
-add-context. Therefore, it is normal that the same counters attached to both the
-stream context and event context show different values for a given event; what
-matters is that they increment at the same rate.

-Please contact Mathieu Desnoyers <mathieu.desnoyers@efficios.com> for
-questions about this TODO list. The "Cleanup/Testing" section would be
-good to go through before integration into mainline. The "Features"
-section is a wish list of features to complete before releasing the
-"LTTng 2.0" final version, but are not required to have LTTng working.
-These features are mostly performance enhancements and instrumentation
-enhancements.
-
-TODO:
-
-A) Cleanup/Testing
-
-	1) Remove debugfs "lttng" file (keep only procfs "lttng" file).
-	   The rationale for this is that this file is needed for
-	   user-level tracing support (LTTng-UST 2.0) intended to be
-	   used on production system, and therefore should be present as
-	   part of a "usually mounted" filesystem rather than a debug
-	   filesystem.
-
-	2) Cleanup wrappers. The drivers/staging/lttng/wrapper directory
-	   contains various wrapper headers that use kallsyms lookups to
-	   work around some missing EXPORT_SYMBOL_GPL() in the mainline
-	   kernel. Ideally, those few symbols should become exported to
-	   modules by the kernel.
-
-	3) Test lib ring buffer snapshot feature.
-	   When working on the lttngtop project, Julien Desfossez
-	   reported that he needed to push the consumer position
-	   forward explicitely with lib_ring_buffer_put_next_subbuf.
-	   This means that although the usual case of pairs of
-	   lib_ring_buffer_get_next_subbuf/lib_ring_buffer_put_next_subbuf
-	   work fine, there is probably a problem that needs to be
-	   investigated in
-	   lib_ring_buffer_get_subbuf/lib_ring_buffer_put_subbuf, which
-	   depend on the producer to push the reader position.
-	   Contact: Julien Desfossez <julien.desfossez@polymtl.ca>
-
-
-B) Features
-
-	1) Integration of the LTTng 0.x trace clocks into
-	   LTTng 2.0.
-	     Currently using mainline kernel monotonic clock. NMIs can
-	     therefore not be traced, and this causes a significant
-	     performance degradation compared to the LTTng 0.x trace
-	     clocks. Imply the creation of drivers/staging/lttng/arch to
-	     contain the arch-specific clock support files.
-	     * Dependency: addition of clock descriptions to CTF.
-	   See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
-	        for the LTTng 0.x git tree.
-
-	2) Port OMAP3 LTTng trace clocks to x86 to support systems
-	   without constant TSC.
-	    * Dependency: (B.1)
-	   See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
-	        for the LTTng 0.x git tree.
-
-	3) Implement mmap operation on an anonymous file created by a
-	   LTTNG_KERNEL_CLOCK ioctl to export data to export
-	   synchronized kernel and user-level LTTng trace clocks:
-	   with:
-	      - shared per-cpu data,
-	      - read seqlock.
-	   The content exported by this shared memory area will be
-	   arch-specific.
-	   * Dependency: (B.1) && (B.2)
-	   See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
-	        for the LTTng 0.x git tree, which has vDSO support for
-	        LTTng trace clock on the x86 architecture.
-
-	3) Integrate the "statedump" module from LTTng 0.x into LTTng
-	   2.0.
-	     * Dependency: addition of "dynamic enumerations" type to CTF.
-	   See: http://git.lttng.org/?p=lttng-modules.git;a=shortlog;h=refs/heads/v0.19-stable
-	        ltt-statedump.c
-
-	4) Generate system call TRACE_EVENT headers for all
-	   architectures (currently done: x86 32/64).
-
-	5) Define "unknown" system calls into instrumentation/syscalls
-	   override files / or do SYSCALL_DEFINE improvements to
-	   mainline kernel to allow automatic generation of these
-	   missing system call descriptions.
-
-	6) Create missing tracepoint event headers files into
-	   instrumentation/events from headers located in
-	   include/trace/events/. Choice: either do as currently done,
-	   and copy those headers locally into the lttng driver and
-	   perform the modifications locally, or push TRACE_EVENT API
-	   modification into mainline headers, which would require
-	   collaboration from Ftrace/Perf maintainers.
-
-	7) Poll: implement a poll and/or epoll exclusive wakeup scheme,
-	   which contradicts POSIX, but protect multiple consumer
-	   threads from thundering herd effect.
-
-	8) Re-integrate sample modules from libringbuffer into
-	   lttng driver. Those modules can be used as example of how to
-	   use libringbuffer in other contexts than LTTng, and are
-	   useful to perform benchmarks of the ringbuffer library.
-	   See: http://www.efficios.com/ringbuffer
-
-	9) NOHZ support for lib ring buffer. NOHZ infrastructure in the
-	   Linux kernel does not support notifiers chains, which does
-	   not let LTTng play nicely with low power consumption setups
-	   for flight recorder (overwrite mode) live traces. One way to
-	   allow integration between NOHZ and LTTng would be to add
-	   support for such notifiers into NOHZ kernel infrastructure.
-
-	10) Turn drivers/staging/lttng/ltt-probes.c probe_list into a
-	    hash table. Turns O(n^2) trace systems registration (cost
-	    for n systems) into O(n). (O(1) per system)
-
-	11) drivers/staging/lttng/probes/lttng-ftrace.c:
-	    LTTng currently uses kretprobes for per-function tracing,
-	    not the function tracer. So lttng-ftrace.c should be used
-	    for "all" function tracing.
-
-	12) drivers/staging/lttng/probes/lttng-types.c:
-	    This is a currently unused placeholder to export entire C
-	    type declarations into the trace metadata, e.g. for support
-	    of describing the layout of structures/enumeration mapping
-	    along with syscall entry events.  The design of this support
-	    will likely change though, and become integrated with the
-	    TRACE_EVENT support within lttng, by adding new macros, and
-	    support for generation of metadata from these macros, to
-	    allow description of those compound types/enumerations.

-LTTng system call tracing
-
-1) lttng-syscall-extractor
-
-You need to build a kernel with CONFIG_FTRACE_SYSCALLS=y and
-CONFIG_KALLSYMS_ALL=y for extraction. Apply the linker patch to get your
-kernel to keep the system call metadata after boot.  Then build and load
-the LTTng syscall extractor module. The module will fail to load (this
-is expected). See the dmesg output for system call metadata.
-
-2) Generate system call TRACE_EVENT().
-
-Take the dmesg metadata and feed it to lttng-syscalls-generate-headers.sh, e.g.,
-from the instrumentation/syscalls directory. See the script header for
-usage example.
-
-After these are created, we just need to follow the new system call additions,
-no need to regenerate the whole thing, since system calls are only appended to.

Subject: staging: comedi: comedi_fops: Replace deprecated strict_strtoul with
 kstrtouint

As reported by checkpatch.pl strict_strtoul should be replaced. It was
replaced with kstrtouint since async->max_bufsize is an unsigned int
anyway.

Subject: net/hyperv: Fix the stop/wake queue mechanism

The ring buffer is only used to pass meta data for outbound packets. The
actual payload is accessed by DMA from the host. So the stop/wake queue
mechanism based on counting and comparing number of pages sent v.s. number
of pages in the ring buffer is wrong. Also, there is a race condition in
the stop/wake queue calls, which can stop xmit queue forever.

The new stop/wake queue mechanism is based on the actual bytes used by
outbound packets in the ring buffer. The check for number of outstanding
sends after stop queue prevents the race condition that can cause wake
queue happening earlier than stop queue.

Subject: staging: line6: fix playback urb transfer buffer calculation

The playback urb transfer buffer calculation does not factor in
LINE6_ISO_PACKETS.  Buffer memory is organized like this in the driver:

  Buffer 0                 Buffer 1                 ...
  [Packet 0, Packet 1, ...][Packet 0, Packet 1, ...][Packet 0, ...]

However, we're lucky that LINE6_ISO_PACKETS is currently defined as 1 so
this patch does not change any behavior.  It's still worth including
this fix in case the LINE6_ISO_PACKETS value is changed in the future.

Subject: staging: line6: eliminate useless index_out variable

Playback urbs use the index_out counter to decide which part of the
playback buffer to use.  Since the urb already has a unique index in
range [0, LINE6_ISO_BUFFERS) there is no need to keep a separate
counter.

Use the urb index instead.  This also eliminates the possibility of two
urbs using the same playback buffer space if they ever complete
out-of-order for some reason.

Subject: staging: line6: wait for urbs in snd_line6_prepare()

The .trigger() pcm callbacks are not allowed to block and cannot wait
until urbs have completed.  We need to ensure that stopping, preparing,
and then restarting a stream always works.

Currently the driver will sometimes return -EBUSY when restarting the
stream because urbs have not completed yet.  This can be triggered by
jackd from userspace.

The solution is to wait on urbs in the .prepare() pcm callback since
blocking is allowed in that callback.  This guarantees that all urbs are
quiesced and ready to be submitted when the start trigger callback is
invoked.

Subject: staging: line6: fixed ALSA/PCM interaction

The PCM subsystem in the Line6 driver is mainly used for PCM playback and
capture by ALSA, but also has other tasks, most notably providing a
low-latency software monitor for devices which don't support hardware
monitoring (e.g., the TonePort series). This patch makes ALSA "play nicely"
with the other components, i.e., prevents it from resetting the isochronous
USB transfer while other PCM tasks (software monitoring) are running.

From a6a918274116d8edc25eb20f6097dedf97b108e2 Mon Sep 17 00:00:00 2001
From: Rob Clark <rob@ti.com>

Subject: staging: drm/omap: DMM based hardware scrolling console

Add support for YWRAP scrolling by shuffling pages around in DMM
instead of sw blits.

Note that fbcon only utilizes this mode if the y resolution is
divided evenly by the font height.  So, for example, a 1920x1080
display using a 16 pixel tall font will not utilize this, but a
1280x1024 display would.

Subject: staging:iio:kfifo_buf: Fix potential buffer overflow in
 iio_read_first_n_kfifo

n is the number of bytes to read, not the number of samples. So if there is
enough data available we will write to the userspace buffer beyond its bounds.
Fix this by copying n bytes maximum. Also round n down to the next multiple of
the sample size, so we will only read complete samples. If the buffer is too
small to hold at least one sample return -EINVAL.

Also update the documentation of read_first_n to reflect the fact that 'n' is
supposed to be in bytes and not in samples.

Subject: staging:iio: iio_trigger contains defunct owner field. Remove it.

This field moved into the trigger_ops structure a while back, but somehow
never quite got cleared up.  This clears the last few drivers to set it
(nothing uses it) and gets rid of it entirely.

Subject: staging: drm/omap: avoid aquiring mutex in atomic context (v2)

omap_gem_roll() could be called by fbcon in atomic context or when
struct_mutext is held.  Avoid aquiring mutex (deadlock), or calling
tiler_pin() (which itself is not safe for atomic context) in these
cases.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This adds the Android switch driver code to the staging tree.

[Note, this code was located in drivers/switch/ in the Android kernel
releases, but as that api wasn't generally accepted, and the interface
is working toward changing to the newly proposed extcon inteface, this
driver was placed here until the extcon code is merged into mainline and
the Android userspace code is converted over to using it. - gregkh]

From 11980c2ac4ccfad21a5f8ee9e12059f1e687bb40 Mon Sep 17 00:00:00 2001

Subject: ashmem: Anonymous shared memory subsystem
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The anonymous shared memory (ashmem) subsystem provides a
Unix-y,file-based shared memory interface to user-space. It
works like anonymous memory (e.g. mmapping fd=0) except if
you share the file descriptor via the usual means, you will
share the mapping. The shared memory can be accessed via both
mmap or file I/O. The backing store is a simple shmem file.

Additionally, ashmem introduces the concept of page pinning.
Pinned pages (the default) behave like any anonymous memory.
Unpinned pages are available to the kernel for eviction during
VM pressure. When repinning the pages, the return value
instructs user-space as to any eviction. In this manner,
user-space processes may implement caching and similar
resource management that efficiently integrates with kernel
memory management.

ashmem: Don't install fault handler for private mmaps.

Ashmem is used to create named private heaps. If this heap is backed
by a tmpfs file it will allocate two pages for every page touched.
In 2.6.27, the extra page would later be freed, but 2.6.29 does not
scan anonymous pages when running without swap so the memory is not
freed while the file is referenced. This change changes the behavior
of private ashmem mmaps to match /dev/zero instead tmpfs.

ashmem: Add common prefix to name reported in /proc/pid/maps

Signed-off-by: Arve Hjønnevåg <arve@android.com>

ashmem: don't require a page aligned size

This makes ashmem more similar to shmem and mmap, by
not requiring the specified size to be page aligned,
instead rounding it internally as needed.

[jstultz: Improved commit subject and included patch description
from rlove. Also moved ashmem files to staging dir, and reworked
code to avoid touching mm/shmem.c while we're in staging.]

Subject: Staging: bcm: Fix information leak in IOCTL_BCM_GET_DRIVER_VERSION

This ioctl, IOCTL_BCM_GET_DRIVER_VERSION, is
responsible for sending the driver version
to userspace. However, the requested size stored
in IoBuffer.OutputLength may be incorrect.
Therefore, we altered the code to send the
exact length of the version, plus one for the
null character.

Subject: Staging: bcm: Fix an invalid dereference to a kmalloc in
 IOCTL_BCM_BULK_WRM

Variable IoBuffer.InputLength is chosen from userspace,
and can therefore be less than the intended size. In this
case,the memory from the kmalloc call is eventually cast
to a PBULKWRM_BUFFER. If the IoBuffer.InputLength does not
meet the minimum size of PBULKWRM_BUFFER, then we will get
a kernel Oops. To resolve this issue, this patch verifies
IoBuffer.InputLength meets the minimum size before invoking
the kmalloc call.

 gma_resume_display() wants 'struct pci_dev *' as it's parameter, so lets pass dev->pdev instead of dev. Fixes the following warning.

Subject: staging:iio: Disallow changing scan elements in all buffered modes

Currently we only disallow changing the scan elements, while the buffer is
enabled, in triggered buffer mode. This patch changes it to disallow it for all
buffered modes. Disabling or enabling scan elements while the buffer is enabled
will cause undefined behavior since the reader will not be able to tell samples
with the new and old scan element set apart and thus wont be able to extract
any meaningful data from the buffer.

Subject: staging:iio: Disallow modifying buffer size when buffer is enabled

The buffer buffer storage is only update when enabling the buffer. Changing the
buffer size while the buffer is enabled will confuse the buffer in regard to
its actual buffer size and can cause potential memory corruption. Thus it is
only safe to modify the buffer size when the buffer is disabled.

Subject: staging:iio: Make sure a device is only opened once at a time

Our buffer implementation does not support multiple concurrent readers. So we
have to ensure that a device is only opened once at a time. So do the same thing
we do for the event fd and introduce a per device busy flag. The flag gets set
when opening the device and gets cleared when closing the device. If a open is
attempted while the busy flag is set we return -EBUSY.

Subject: staging:iio: Drop buffer mark_param_change callback

Right now we have a mark_param_change callback in the buffer access
functions struct, which should be called whenever the parameters (length,
bytes per datum) of the buffer change. But it is only called when the user
changes the buffer size, not when the bytes per datum change. Additionally each
buffer implementation already keeps track internally whether its parameters
have changed, making the call to mark_param_change after changing the buffer
length redundant. Since each buffer implementation knows best when one of its
parameters has changed just make tracking of this internal and drop the
mark_param_change callback.

Subject: staging:iio: Drop {mark,unmark}_in_use callbacks

These callbacks are currently used by the individual buffer implementations to
ensure that the request_update callback is not issued while the buffer is in use.
But the core already provides sufficient measures to prevent this from happening
in the first place. So it is safe to remove them.

There is one functional change due to this patch. Since the buffer is no longer
marked as in use when the chrdev is opened, it is now possible to enable the
buffer while it is opened. This did not work before, because mark_param_change
did fail if the buffer was marked as in use.

Subject: staging: usbip: removed dead code from receive function

The usbip_xmit function supported sending and receiving data, however
the sending part of the function was never used/executed. Renamed the
function to usbip_recv, and removed the unused code.

From 32c44cb5b9fdc6eaa445bd622008dd672a3dd1a7 Mon Sep 17 00:00:00 2001
From: Sean MacLennan <seanm@seanm.ca>
Date: Mon, 19 Dec 2011 23:20:41 -0500
Subject: staging/rtl8192e: Convert to lib80211_crypt_data and
 lib80211_crypt_ops

Convert rtllib_crypt_data to lib80211_crypt_data and
rtllib_crypt_ops to lib80211_crypt_ops.

This is almost a 1:1 replacement, only extra_prefix_len and
extra_postfix_len changed.

From 3b148be0df8e45a0259d7e84001cf02e897af614 Mon Sep 17 00:00:00 2001
From: Sean MacLennan <seanm@seanm.ca>
Date: Mon, 19 Dec 2011 23:23:08 -0500
Subject: staging/rtl8192e: Register against lib80211

Convert rtllib from registering the crypt drivers against rtllib_crypt
and instead register the against lib80211. The crypto functions have
R- prepended (R-CCMP, R-TKIP, R-WEP) so they will not clash with the
lib80211 versions.

We cannot use the lib80211 crypt drivers since the rtl8192e has some
hardware support that is not handled by the lib80211 crypt drivers.

Subject: net/hyperv: Remove unnecessary kmap_atomic in netvsc driver

__get_free_pages() doesn't return HI memory, so the memory is always mapped.
kmap_atomic() is not necessary here. This patch removes the kmap_atomic()
calls and related code for locking and page manipulation.
