      Pull component updates from Russell King:
       "Updates for the component helper merged last year.
      
        This update removes the old add_components method of detecting and
        looking up the components associated with a master device.  Last time
        I checked during the 4.4-rc cycle, there were no users of the old
        interfaces, as has been the case for some time now.  Breakage due to
        conflicting development is possible, in which case this pull will have
        to be reverted - however, these changes have been in linux-next since
        Dec 7th without any problems reported.
      
        Removal of that then allows us to change the way we track components
        internally, allowing us to release data that has been used for
        matching at the appropriate time, thereby allowing any resource leaks
        caused by that missing functionality to be resolved"
      
      * 'component' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
        component: add support for releasing match data
        component: track components via array rather than list
        component: move check for unbound master into try_to_bring_up_masters()
        component: remove old add_components method

      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.
      
         - Remove work queues from drivers: leds-tlc591xx, leds-88pm860x, leds-adp5520,
              leds-bd2802, leds-blinkm, leds-lm3533, leds-lm3642, leds-pca9532,
              leds-lp3944, leds-lp55xx, leds-lp8788, leds-lp8860, leds-pca955x,

              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,
              - add little endian support,
              - 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:

      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.
      
        Summary:
      
         - New drivers:
            - PXA2xx pin controller support
            - Broadcom NSP pin controller support
      
         - New subdrivers:
            - Samsung EXYNOS5410 support
            - Qualcomm MSM8996 support
            - Qualcomm PM8994 support
            - Qualcomm PM8994 MPP support
            - Allwinner sunxi H3 support
            - Allwinner sunxi A80 support
            - Rockchip RK3228 support
      
         - Rename the Cygnus pinctrl driver to "iproc" as it is more generic
           than was originally thought.
      
         - A bunch of Lantiq/Xway updates especially from the OpenWRT people.
      
         - Several refactorings for the Super-H SH PFC pin controllers.
           Adding SCIF_CLK support.
      
         - Several fixes to the Atlas 7 driver.

         - 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

              [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

       "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.

         - Late-breaking fix to sysrq-generated crash.
      
        One thing I should note is that these pieces of documentation are
        fairly large files:

        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

      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.
