759f42987f 9P: Fix race between p9_write_work() and p9_fd_request()
Race scenario:

thread A			thread B

p9_write_work()                p9_fd_request()

if (list_empty
  (&m->unsent_req_list))
  ...

                               spin_lock(&client->lock);
                               req->status = REQ_STATUS_UNSENT;
                               list_add_tail(..., &m->unsent_req_list);
                               spin_unlock(&client->lock);
                               ....
                               if (n & POLLOUT &&
                               !test_and_set_bit(Wworksched, &m->wsched)
                               schedule_work(&m->wq);
                               --> not done because Wworksched is set

  clear_bit(Wworksched, &m->wsched);
  return;

--> nobody will take care of sending the new request.

This is not very likely to happen though, because p9_write_work()
being called with an empty unsent_req_list is not frequent.
But this also means that taking the lock earlier will not be costly.

12250d843e Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux
Pull i2c-embedded changes from Wolfram Sang:
 "The changes for i2c-embedded include:

   - massive rework of the omap driver
   - massive rework of the at91 driver.  In fact, the old driver gets
     removed; I am okay with this approach since the old driver was
     depending on BROKEN and its limitations made it practically
     unusable, so people used bitbanging instead.  But even if there are
     users, there is no platform_data or module parameter which would
     need to be converted.  It is just another driver doing I2C
     transfers, just way better.  Modifications of arch/arm/at91 related
     files have proper acks from the maintainer.
   - new driver for R-Car I2C
   - devicetree and generic_clock conversions and fixes
   - usual driver fixes and changes.

  The rework patches have come a long way and lots of people have been
  involved in creating/testing them.  Most patches have been in
  linux-next at least since 3.6-rc5.  A few have been added in the last
  week, I have to admit.

  An unexpected (but welcome :)) peak in private life is the cause for
  that.  The "late" patches shouldn't cause any merge conflicts and I
  will have a special eye on them during the stabilization phase.  This
  is an exception and I want to have the patches in place properly in
  time again for the next kernels."

da06a8d7be ARM: SoC fixes
A series of fixes (and in some cases, some cleanups):
 
 Via Tony Lindgren:
 - A collection of OMAP regression fixes, in particular because firmware
   no longer sets up all pin states before starting the kernel.
 - cpufreq fixes for OMAP (Rafael is on vacation and this was pre-agreed).
 - A longer series of misc regression fixes and cleanups, warning removals,
   etc for OMAP

49999ab27e autofs4 - fix reset pending flag on mount fail
In autofs4_d_automount(), if a mount fail occurs the AUTOFS_INF_PENDING
mount pending flag is not cleared.

One effect of this is when using the "browse" option, directory entry
attributes show up with all "?"s due to the incorrect callback and
subsequent failure return (when in fact no callback should be made).

Pull block IO update from Jens Axboe:
 "Core block IO bits for 3.7.  Not a huge round this time, it contains:

   - First series from Kent cleaning up and generalizing bio allocation
     and freeing.

   - WRITE_SAME support from Martin.

   - Mikulas patches to prevent O_DIRECT crashes when someone changes
     the block size of a device.

   - Make bio_split() work on data-less bio's (like trim/discards).

   - A few other minor fixups."

Fixed up silent semantic mis-merge as per Mikulas Patocka and Andrew
Morton.  It is due to the VM no longer using a prio-tree (see commit
6b2dbba8b6: "mm: replace vma prio_tree with an interval tree").

So make set_blocksize() use mapping_mapped() instead of open-coding the
internal VM knowledge that has changed.

8dc0839510 rtc: kconfig: fix RTC_INTF defaults connected to RTC_CLASS
Commit 6b8029fab6 ("rtc: kconfig: remove unnecessary dependencies")
removed various 'depends on RTC_CLASS' dependencies but also removed a
few 'default RTC_CLASS' statements, which actually changed default
behavior.

This resulted in the various RTC interfaces (sysfs, proc, dev) all being
disabled by default, even when RTC_CLASS is enabled:

   # CONFIG_RTC_INTF_SYSFS is not set
   # CONFIG_RTC_INTF_PROC is not set
   # CONFIG_RTC_INTF_DEV is not set

which is different from previous behavior (all of these where enabled.)

To fix, add back the 'default RTC_CLASS' statments to each of the
RTC_INTF_* options.

I noticed this because some RTC tests started failing on my TI OMAP
platforms because /dev/rtc0 was not present anymore, even though the
driver was present and RTC_CLASS was enabled.

3e1aa66bd4 lib/kasprintf.c: use kmalloc_track_caller() to get accurate traces for kvasprintf
Previously kvasprintf() allocation was being done through kmalloc(),
thus producing an inaccurate trace report.

This is a common problem: in order to get accurate callsite tracing, a
lib/utils function shouldn't allocate kmalloc but instead use
kmalloc_track_caller.

2574740d1f rapidio: update asynchronous discovery initialization
Update discovery process initialization based on Andrew Morton's comments:
https://lkml.org/lkml/2012/10/3/552.

This update processes all enumerating mports first and schedules discovery
work after that. If the initialization routine fails to allocate resources
needed to execute discovery, it abandons discovery for all ports.

899649b7d4 vfio: Fix PCI INTx disable consistency
The virq_disabled flag tracks the userspace view of INTx masking
across interrupt mode changes, but we're not consistently applying
this to the interrupt and masking handler notion of the device.
Currently if the user sets DisINTx while in MSI or MSIX mode, then
returns to INTx mode (ex. rebooting a qemu guest), the hardware has
DisINTx+, but the management of INTx thinks it's enabled, making it
impossible to actually clear DisINTx.  Fix this by updating the
handler state when INTx is re-enabled.

We need to be ready to recieve an interrupt as soon as we call

2474542f64 pwm: Changes for v3.7-rc1
All legacy PWM providers have now been moved to the PWM subsystem. The
 plan for 3.8 is to adapt all board files to provide a lookup table for
 PWM devices in order to get rid of the global namespace. Subsequently,
 users of the legacy pwm_request() and pwm_free() functions can be
 migrated to the new pwm_get() and pwm_put() functions. Once this has
 been completed, the legacy API and the compatibility code in the core
 can be removed.
 
 In addition to the above, these changes also add support for configuring
 the polarity of a PWM signal (currently only supported on ECAP and
 EHRPWM) and include a much needed rework of the i.MX driver. Managed
 functions to obtain and release a PWM device (devm_pwm_get() and
 devm_pwm_put()) have been added and the pwm-backlight driver has been
 updated to use them. If the PWM subsystem hasn't been enabled, dummy
 functions are provided that allow the subsystem to safely compile out.
 
 Some common checks on input parameters have been moved to the core and
 removed from the drivers. Finally, a small fix corrects the description
 of the PWM specifier's second cell in the device tree representation.

Pull scsi target updates from Nicholas Bellinger:
 "Things have been calm for the most part with no new fabric drivers in
  flight for v3.7 (we're up to eight now !), so this update is primarily
  focused on addressing a few long-standing items within target-core and
  iscsi-target fabric code.

  The highlights include:

   - target: Simplify fabric sense data length handling (roland)
   - qla2xxx: Fix endianness of task management response code (roland)
   - target: fix truncation of mode data, support zero allocation length
     (paolo)
   - target: Properly support zero-length commands in normal processing
     path (paolo)
   - iscsi-target: Correctly set 0xffffffff field within ISCSI_OP_REJECT
     PDU (ronnie + nab)
   - iscsi-target: Add explicit set of cache_dynamic_acls=1 for TPG
     demo-mode (ronnie + nab)
   - target/file: Re-enable optional fd_buffered_io=1 operation (nab +
     hch)
   - iscsi-target: Add MaxXmitDataSegmenthLength forr target ->
     initiator MDRSL declaration (nab)
   - target: Add target_submit_cmd_map_sgls for SGL fabric memory
     passthrough (nab + hch)
   - tcm_loop: Convert I/O path to use target_submit_cmd_map_sgls (hch +
     nab)
   - tcm_vhost: Convert I/O path to use target_submit_cmd_map_sgls (nab
     + hch)

  The last series for adding a new target_submit_cmd_map_sgls() fabric
  caller (as requested by hch) that accepts pre-allocated SGL memory
  (using existing logic), along with converting tcm_loop + tcm_vhost has
  only been in -next for the last days, but has gotten enough review
  +testing and is clear enough a mechanical change that I think it's
  reasonable to merge for -rc1 code.

  Thanks again to everyone who contributed this round! Extra special
  thanks to Roland (PureStorage) for tracking down the qla2xxx target
  TMR response code endian issue, and to Paolo (Redhat) for resolving
  the long standing zero-length CDB issues within target-core between
  virtual and pSCSI backends."

From Tony Lindgren:

These were agreed to be merged via arm soc tree as Rafael
is on vacation.

From Kevin Hilman <khilman@deeprootsystems.com>:

This series a couple bug fixes and a couple fixes that make this
driver support recently added OMAP-based SoCs.

The 'get_cpu_device' patch is needed due to a change in the OMAP
OMAP PM core code which enforces use of get_cpu_device() instead of
a deprecated OMAP-specific API.

The usage of plat/*.h headers breaks single zImage, so platforms are
cleaning up and/or removing plat/*.h so the driver needs to be fixed
accordingly.

This series is based on the merge of Rafael's pm-for-3.7-rc1 tag into
Linus' master branch: commit 16642a2e7b.
