      Pull clock framework update from Michael Turquette:
       "The common clock framework changes for 3.9 are almost entirely fixes.
      
        None are dire enough to be Cc'd to stable which may be interpreted to
        mean that users of the framework are reaching stability.  Lots of new
        adoption of this framework is via DeviceTree data and that comes
        through the respective architecture and platform trees instead of
        through the clk framework tree.
      
        Two new features are improved debugfs output and an improvement to how
        DT clocks are initialized by reusing a common method."

      Pull battery updates from Anton Vorontsov:
       "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
           series.
      
         - New health properties for the power supplies: "Watchdog timer
           expire" and "Safety timer expire"
      
         - As usual, a bunch of fixes/cleanups here and there"
      
      * tag 'for-v3.9' of git://git.infradead.org/battery-2.6: (81 commits)
        bq2415x_charger: Add support for offline and 100mA mode
        generic-adc-battery: Fix forever loop in gab_remove()
        goldfish_battery: Add missing GENERIC_HARDIRQS dependency
        da9030_battery: Include notifier.h

        ds2782_battery: Add power_supply_changed() calls for proper uevent support
        power: Add battery driver for goldfish emulator
        u8500-charger: Delay for USB enumeration
        ab8500-bm: Remove individual [charger|btemp|fg|chargalg] pdata structures
        ab8500-charger: Do not touch VBUSOVV bits
        ab8500-fg: Use correct battery charge full design
        pm2301: LPN mode control support
        pm2301: Enable vbat low monitoring
        ab8500-bm: Flush all work queues before suspending
        ab8500-fg: Go to INIT_RECOVERY when charger removed
        ab8500-charger: Add support for autopower on AB8505 and AB9540
        abx500-chargalg: Add new sysfs interface to get current charge status
        ...
      
      Fix up fairly straightforward conflicts in the ab8500 driver.  But since
      it seems to be ARM-specific, I can't even compile-test the result..

      Linus Torvalds authored
      Pull pinctrl changes from Linus Walleij:
       "These are the main pinctrl changes for the v3.9 merge window.  The
        most interesting change by far is how the device core grabs pinctrl
        default handles avoiding the need to stick boilerplate into driver
        consumers.
      
         - Grabbing of default pinctrl handles from the device core.  These
           are the hunks hitting drivers/base.  All is ACKed by Greg, after a
           long discussion about different alternatives.
      
         - Some stuff also touches the MFD and ARM SoC trees, this has been
           coordinated and ACKed.
      
         - New drivers for:
           - The Tegra 114 sub-SoC
           - Allwinner sunxi
           - New ABx500 driver and sub-SoC drivers for AB8500, AB8505, AB9540
             and AB8540.
      
         - Make it possible for hogged pins to enter a sleep mode, and make it
           possible for drivers to control that mode.
      
         - Various clean-up, extensions and device tree support to various pin
           controllers."

           to take advantage of the cache infrastructure, contributed by
           Andrey Smirnov.
      
         - Several small improvements to the support for wake capable IRQs.
      
         - Support for asynchronous I/O, allowing us to come much closer to
           saturating fast buses like SPI.
      
         - Support for simple array caches, giving higher performance for use
           with MMIO devices.

      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.

      Linus Torvalds authored
      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."

       "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.

      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
              # ................  .......  .................  ..........................
                  99.84%  99.76%  noploop  noploop            [.] main
                   0.07%   0.00%  noploop  ld-2.15.so         [.] strcmp

                   0.03%   0.03%  noploop  [kernel.kallsyms]  [k] sched_clock_cpu
                   0.02%   0.00%  noploop  [kernel.kallsyms]  [k] account_user_time
                   0.01%   0.00%  noploop  [kernel.kallsyms]  [k] __alloc_pages_nodemask

                   0.00%   0.02%  noploop  [kernel.kallsyms]  [k] __current_kernel_time
      
           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,
           just press 's' and a menu with the valid files found in the current
           directory will be presented, from Feng Tang.
      
         - Add support to display whole group data for raw columns, from Jiri
           Olsa.
      
         - Add per processor socket count aggregation in perf stat, from
           Stephane Eranian.
      
         - Add interval printing in 'perf stat', from Stephane Eranian.
      
         - 'perf test' improvements
      
         - Add support for wildcards in tracepoint system name, from Jiri
           Olsa.
      
         - Add anonymous huge page recognition, from Joshua Zhu.
      
         - perf build-id cache now can show DSOs present in a perf.data file
           that are not in the cache, to integrate with build-id servers being
           put in place by organizations such as Fedora.
      
         - 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.
      
         - Fix mmap limitations on 32-bit, fix from David Miller.
      
         - 'perf bench numa mem' NUMA performance measurement suite
      
         - ... and lots of fixes, performance improvements, cleanups and other
           improvements I failed to list - see the shortlog and git log for
           details."

      Pull irq core changes from Ingo Molnar:
       "The biggest changes are the IRQ-work and printk changes from Frederic
        Weisbecker, which prepare the code for 'full dynticks' (the ability to
        stop or slow down the periodic tick arbitrarily, not just in idle time
        as today):
      
         - Don't stop tick with irq works pending.  This fix is generally
           useful and concerns archs that can't raise self IPIs.
      
         - Flush irq works before CPU offlining.
      
         - Introduce "lazy" irq works that can wait for the next tick to be
           executed, unless it's stopped.
      
         - Implement klogd wake up using irq work.  This removes the ad-hoc
           printk_tick()/printk_needs_cpu() hooks and make it working even in
           dynticks mode.
