 "Four new drivers:

   - goldfish_battery:

     This is Android Emulator battery driver.  Originally from Google,
     but Intel folks reshaped it for mainline

   - pm2301_charger:

     A new driver for ST-Ericsson 2301 Power Management chip, uses
     AB8500 battery management core

   - qnap-poweroff:

     The driver adds poweroff functionality for QNAP NAS boxes

   - restart-poweroff:

     A generic driver that implements 'power off by restarting'.  The
     actual poweroff functionality is implemented through a bootloader,
     so Linux' task is just to restart the box.  The driver is useful on
     Buffalo Linkstation LS-XHL and LS-CHLv2 boards.  Andrew Lunn worked
     on submitting the driver (as well as qnap-poweroff above).

  Additionally:

   - A lot of fixes for ab8500 drivers.  This is a part of efforts of
     syncing internal ST-Ericsson development tree with the mainline.
     Lee Jones @ Linaro worked on compilation and reshaping these

Pull cpuset changes from Tejun Heo:

 - Synchornization has seen a lot of changes with focus on decoupling
   cpuset synchronization from cgroup internal locking.

   After this change, there only remain a couple of mostly trivial
   dependencies on cgroup_lock outside cgroup core proper.  cgroup_lock
   is scheduled to be unexported in this devel cycle.

   This will finally remove the fragile locking order around cgroup
   (cgroup locking wants to / should be one of the outermost but yet has
   been acquired from deep inside individual controllers).

 - At this point, Li is most knowlegeable with cpuset and taking over
   the maintainership of cpuset.

Prepare first set of updates for 3.9 merge window.

Pull workqueue changes from Tejun Heo:
 "A lot of reorganization is going on mostly to prepare for worker pools
  with custom attributes so that workqueue can replace custom pool
  implementations in places including writeback and btrfs and make CPU
  assignment in crypto more flexible.

  workqueue evolved from purely per-cpu design and implementation, so
  there are a lot of assumptions regarding being bound to CPUs and even
  unbound workqueues are implemented as an extension of the model -
  workqueues running on the special unbound CPU.  Bulk of changes this
  round are about promoting worker_pools as the top level abstraction
  replacing global_cwq (global cpu workqueue).  At this point, I'm
  fairly confident about getting custom worker pools working pretty soon
  and ready for the next merge window.

  Lai's patches are replacing the convoluted mb() dancing workqueue has
  been doing with much simpler mechanism which only depends on
  assignment atomicity of long.  For details, please read the commit
  message of 0b3dae68 ("workqueue: simplify is-work-item-queued-here
  test").  While the change ends up adding one pointer to struct
  delayed_work, the inflation in percentage is less than five percent
  and it decouples delayed_work logic a lot more cleaner from usual work
  handling, removes the unusual memory barrier dancing, and allows for
  further simplification, so I think the trade-off is acceptable.

  There will be two more workqueue related pull requests and there are
  some shared commits among them.  I'll write further pull requests
  assuming this pull request is pulled first."

Pull workqueue [delayed_]work_pending() cleanups from Tejun Heo:
 "This is part of on-going cleanups to remove / minimize usages of
  workqueue interfaces which are deprecated and/or misleading.

  This round drops a number of usages of [delayed_]work_pending(), which
  are dangerous as they lack any form of synchronization and thus often
  lead to buggy / unnecessary code.  There are a couple legitimate use
  cases in kernel.  Hopefully, they can be converted and
  [delayed_]work_pending() can be removed completely.  Even if not,
  removing most of misuses should make it more difficult to find
  examples of misuses and thus slow down growth of them.

  These changes are independent from other workqueue changes."

Pull perf changes from Ingo Molnar:
 "There are lots of improvements, the biggest changes are:

  Main kernel side changes:

   - Improve uprobes performance by adding 'pre-filtering' support, by
     Oleg Nesterov.

   - Make some POWER7 events available in sysfs, equivalent to what was
     done on x86, from Sukadev Bhattiprolu.

   - tracing updates by Steve Rostedt - mostly misc fixes and smaller
     improvements.

   - Use perf/event tracing to report PCI Express advanced errors, by
     Tony Luck.

   - Enable northbridge performance counters on AMD family 15h, by Jacob
     Shin.

   - This tracing commit:

        tracing: Remove the extra 4 bytes of padding in events

     changes the ABI.  All involved parties (PowerTop in particular)
     seem to agree that it's safe to do now with the introduction of
     libtraceevent, but the devil is in the details ...

  Main tooling side changes:

   - Add 'event group view', from Namyung Kim:

     To use it, 'perf record' should group events when recording.  And
     then perf report parses the saved group relation from file header
     and prints them together if --group option is provided.  You can
     use the 'perf evlist' command to see event group information:

        $ perf record -e '{ref-cycles,cycles}' noploop 1
        [ perf record: Woken up 2 times to write data ]
        [ perf record: Captured and wrote 0.385 MB perf.data (~16807 samples) ]

        $ perf evlist --group
        {ref-cycles,cycles}

     With this example, default perf report will show you each event
     separately.

     You can use --group option to enable event group view:

        $ perf report --group
        ...
        # group: {ref-cycles,cycles}
        # ========
        # Samples: 7K of event 'anon group { ref-cycles, cycles }'
        # Event count (approx.): 6876107743
        #
        #         Overhead  Command      Shared Object                      Symbol

     As you can see the Overhead column now contains both of ref-cycles
     and cycles and header line shows group information also - 'anon
     group { ref-cycles, cycles }'.  The output is sorted by period of
     group leader first.

   - Initial GTK+ annotate browser, from Namhyung Kim.

   - Add option for runtime switching perf data file in perf report,

   - perf top now shares more of the evsel config/creation routines with
     'record', paving the way for further integration like 'top'
     snapshots, etc.

   - perf top now supports DWARF callchains.

Make sure to clear the mode bits from the config register before setting the new
mode. Otherwise we might end up with a different mode than we want to.

commit d8e794df ("workqueue: set
delayed_work->timer function on initialization") exports function
delayed_work_timer_fn() only for GPL modules. This makes delayed-works
unusable for non-GPL modules, because initialization macro now requires
GPL symbol. For example schedule_delayed_work() available for non-GPL.
