Pull arm[64] perf updates from Will Deacon:
 "In the past, I have funnelled perf updates through the respective
  architecture trees, but now that the arm/arm64 perf driver has been
  largely consolidated under drivers/perf/, it makes more sense to send
  a separate pull, particularly as I'm listed as maintainer for all the
  files involved.  I offered the branch to arm-soc, but Arnd suggested
  that I just send it to you directly.

  So, here is the arm/arm64 perf queue for 4.5.  The main features are
  described below, but the most useful change is from Drew, which
  advertises our architected event mapping in sysfs so that the perf
  tool is a lot more user friendly and no longer requires the use of
  magic hex constants for profiling common events.

   - Support for the CPU PMU in Cortex-A72

   - Add sysfs entries to describe the architected events and their
     mappings for PMUv{1-3}"

Pull arm64 updates from Will Deacon:
 "Here is the core arm64 queue for 4.5.  As you might expect, the
  Christmas break resulted in a number of patches not making the final
  cut, so 4.6 is likely to be larger than usual.  There's still some
  useful stuff here, however, and it's detailed below.

  The EFI changes have been Reviewed-by Matt and the memblock change got
  an "OK" from akpm.

  Summary:

   - Support for a separate IRQ stack, although we haven't reduced the
     size of our thread stack just yet since we don't have enough data
     to determine a safe value

   - Refactoring of our EFI initialisation and runtime code into
     drivers/firmware/efi/ so that it can be reused by arch/arm/.

   - Ftrace improvements when unwinding in the function graph tracer

   - Document our silicon errata handling process

   - Cache flushing optimisation when mapping executable pages

   - Support for hugetlb mappings using the contiguous hint in the pte"

Pull device mapper updates from Mike Snitzer:

 - The most significant set of changes this cycle is the Forward Error
   Correction (FEC) support that has been added to the DM verity target.

   Google uses DM verity on all Android devices and it is believed that
   this FEC support will enable DM verity to recover from storage
   failures seen since DM verity was first deployed as part of Android.

 - A stable fix for a race in the destruction of DM thin pool's
   workqueue

 - A stable fix for hung IO if a DM snapshot copy hit an error

 - A few small cleanups in DM core and DM persistent data.

 - A couple DM thinp range discard improvements (address atomicity of
   finding a range and the efficiency of discarding a partially mapped
   thin device)

 - Add ability to debug DM bufio leaks by recording stack trace when a
   buffer is allocated.  Upon detected leak the recorded stack is
   dumped.

Pull LED subsystem updates from Jacek Anaszewski:
 "Besides regular driver updates, we introduce a portion of LED core
  improvements, that allow to avoid the need for using work queues in
  the LED class drivers, that set brightness in a blocking way.

  Affected LED class drivers are being optimized accordingly.

   - LED core improvements:
        - use EXPORT_SYMBOL_GPL consistently,
        - add two new LED_BLINK_ flags,
        - rename brightness_set_sync op to brightness_set_blocking,
        - add led_set_brightness_nosleep{nopm} functions,
        - use set_brightness_work for the blocking op,
        - drivers shouldn't enforce SYNC/ASYNC brightness setting,
        - turn off the LED and wait for completion on unregistering LED
          class device,
        - add managed version of led_trigger_register,
        - add description of brightness setting API to the LED class doc.

        leds-max77693, leds-aat1290, leds-ktd2692, leds-gpio, leds-pwm,
        leds-lm355x, leds-ns2.

   - Replace brightness_set op with a new brightness_set_blocking op to
     make the drivers compatible with led triggers: leds-ipaq-micro,
     leds-powernv.

   - Add missing of_node_put: leds-ktd2692, leds-aat1290, leds-max77693.

   - Make the driver explicitly non-modular: ledtrig-cpu,
     ledtrig-ide-disk, leds-syscon.

   - Improvements to leds-bcm6328:
        - reuse bcm6328_led_set() instead of copying its functionality,
        - swap LED ON and OFF definitions,
        - improve blink support,
        - simplify duplicated unlock in bcm6328_blink_set,

        - remove unneded lock when checking initial LED status,
        - add HAS_IOMEM dependency,
        - code cleaning.

   - Improvements to leds-bcm6358:
        - use bcm6358_led_set() in order to get rid of the lock,
        - merge bcm6358_led_mode and bcm6358_led_set,
        - add little endian support,
        - remove unneded lock when checking initial LED status,
        - add HAS_IOMEM dependency,
        - remove unneeded busy status check.

   - Call led_pwm_set() in leds-pwm to enforce default LED_OFF.

   - Fix duration to be msec instead of jiffies: ledtrig-transient.

   - Removing NULL check: leds-powernv.

   - Use platform_register/unregister_drivers(): leds-sunfire.

   - Fix module license specification: ledtrig-oneshot.

   - Fix driver description and make license match the header: leds-pwm.

   - Remove checking for state < 1 in flash_strobe_store():
     led-class-flash.

   - Use led_set_brightness_sync for torch brightness:
     v4l2-flash-led-class"

     with the conversions that readl() and writel() do to little endian
     on big endian systems (with some DT updates to fix some workarounds

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control patches for the v4.5 series.

  Notably I have a patch to driver core from Stephen Boyd in the pull
  request, this has been ACKed by Greg so it should be OK.  The internal
  API needed some tweaking to allow modular Qualcomm pin controllers.

  There is a bit of development history in here but it should all add up
  nicely and has boiled in linux-next.  For example I merged in v4.4-rc5
  to get rid of some nasty merge conflicts.

   - Introduce the 'perf stat record/report' workflow:

     Generate perf.data files from 'perf stat', to tap into the
     scripting capabilities perf has instead of defining a 'perf stat'
     specific scripting support to calculate event ratios, etc.

     Simple example:

        $ perf stat record -e cycles usleep 1

         Performance counter stats for 'usleep 1':

               1,134,996      cycles

             0.000670644 seconds time elapsed

        $ perf stat report

         Performance counter stats for '/home/acme/bin/perf stat record -e cycles usleep 1':

               1,134,996      cycles

             0.000670644 seconds time elapsed

        $

     It generates PERF_RECORD_ userspace records to store the details:

        $ perf report -D | grep PERF_RECORD
        0xf0 [0x28]: PERF_RECORD_THREAD_MAP nr: 1 thread: 27637
        0x118 [0x12]: PERF_RECORD_CPU_MAP nr: 1 cpu: 65535

        0x1da [0x18]: PERF_RECORD_STAT_ROUND
        [acme@ssdandy linux]$

     An effort was made to make perf.data files generated like this to
     not generate cryptic messages when processed by older tools.

     The 'perf script' bits need rebasing, will go up later.

   - Make command line options always available, even when they depend
     on some feature being enabled, warning the user about use of such
     options (Wang Nan)

   - Support hw breakpoint events (mem:0xAddress) in the default output
     mode in 'perf script' (Wang Nan)

   - Fixes and improvements for supporting annotating ARM binaries,
     support ARM call and jump instructions, more work needed to have
     arch specific stuff separated into tools/perf/arch/*/annotate/
     (Russell King)

   - Add initial 'perf config' command, for now just with a --list
     command to the contents of the configuration file in use and a
     basic man page describing its format, commands for doing edits and
     detailed documentation are being reviewed and proof-read.  (Taeung
     Song)

   - Allows BPF scriptlets specify arguments to be fetched using DWARF
     info, using a prologue generated at compile/build time (He Kuang,
     Wang Nan)

   - Allow attaching BPF scriptlets to module symbols (Wang Nan)

   - Allow attaching BPF scriptlets to userspace code using uprobe (Wang
     Nan)

   - BPF programs now can specify 'perf probe' tunables via its section
     name, separating key=val values using semicolons (Wang Nan)

     Testing some of these new BPF features:

        Use case: get callchains when receiving SSL packets, filter then in the
                  kernel, at arbitrary place.

   - Use 'perf probe' various options to list functions, see what
     variables can be collected at any given point, experiment first
     collecting without a filter, then filter, use it together with
     'perf trace', 'perf top', with or without callchains, if it
     explodes, please tell us!

   - Introduce a new callchain mode: "folded", that will list per line

Pull RCU updates from Ingo Molnar:
 "The changes in this cycle were:

   - Adding transitivity uniformly to rcu_node structure ->lock
     acquisitions.  (This is implemented by the first two commits on top
     of v4.4-rc2 due to the pervasive nature of this change.)

   - Documentation updates, including RCU requirements.

   - Expedited grace-period changes.

   - Miscellaneous fixes.

   - Linked-list fixes, courtesy of KTSAN.

   - Torture-test updates.

   - Late-breaking fix to sysrq-generated crash.

  One thing I should note is that these pieces of documentation are
  fairly large files:

    .../RCU/Design/Requirements/Requirements.html      | 2897 ++++++++++++++++++++
    .../RCU/Design/Requirements/Requirements.htmlx     | 2741 ++++++++++++++++++

  and are written in HTML, not the usual .txt style.  I hope they are
  fine"

Paul McKenney explains the html docs:
 "For whatever it is worth, the reason for this unconventional choice
  was that attempts to do the diagrams in ASCII art failed miserably.

  And attempts to do ASCII art for the upcoming documentation of the
  data structures failed even more miserably"

The defconfig build of m68k was failing with the error:
implicit declaration of function '__pfn_to_phys'

Other architectures have added <asm/memory.h>, but if we do so here then
we will also get redeclaration of some other functions. So it is better
to copy these macros into page.h.
