      Pull cgroup updates from Tejun Heo:
      
       - a new PIDs controller is added.  It turns out that PIDs are actually
         an independent resource from kmem due to the limited PID space.
      
       - more core preparations for the v2 interface.  Once cpu side interface
         is settled, it should be ready for lifting the devel mask.
         for-4.3-unified-base was temporarily branched so that other trees
         (block) can pull cgroup core changes that blkcg changes depend on.
      
       - a non-critical idr_preload usage bug fix.

      Pull power management and ACPI updates from Rafael Wysocki:
       "From the number of commits perspective, the biggest items are ACPICA
        and cpufreq changes with the latter taking the lead (over 50 commits).
      
        On the cpufreq front, there are many cleanups and minor fixes in the
        core and governors, driver updates etc.  We also have a new cpufreq
        driver for Mediatek MT8173 chips.
      
        ACPICA mostly updates its debug infrastructure and adds a number of
        fixes and cleanups for a good measure.
      
        The Operating Performance Points (OPP) framework is updated with new
        DT bindings and support for them among other things.
      
        We have a few updates of the generic power domains framework and a
        reorganization of the ACPI device enumeration code and bus type
        operations.
      
        And a lot of fixes and cleanups all over.
      
        Included is one branch from the MFD tree as it contains some
        PM-related driver core and ACPI PM changes a few other commits are
        based on.
      
        Specifics:
      
         - ACPICA update to upstream revision 20150818 including method
           tracing extensions to allow more in-depth AML debugging in the
           kernel and a number of assorted fixes and cleanups (Bob Moore, Lv
           Zheng, Markus Elfring).
      
         - ACPI sysfs code updates and a documentation update related to AML
           method tracing (Lv Zheng).
      
         - ACPI EC driver fix related to serialized evaluations of _Qxx
           methods and ACPI tools updates allowing the EC userspace tool to be
           built from the kernel source (Lv Zheng).
      
         - ACPI processor driver updates preparing it for future introduction
           of CPPC support and ACPI PCC mailbox driver updates (Ashwin
           Chaugule).
      
         - ACPI interrupts enumeration fix for a regression related to the
           handling of IRQ attribute conflicts between MADT and the ACPI
           namespace (Jiang Liu).
      
         - Fixes related to ACPI device PM (Mika Westerberg, Srinidhi
           Kasagar).
      
         - ACPI device registration code reorganization to separate the
           sysfs-related code and bus type operations from the rest (Rafael J
           Wysocki).
      
         - Assorted cleanups in the ACPI core (Jarkko Nikula, Mathias Krause,
           Andy Shevchenko, Rafael J Wysocki, Nicolas Iooss).
      
         - ACPI cpufreq driver and ia64 cpufreq driver fixes and cleanups (Pan
           Xinhui, Rafael J Wysocki).
      
         - cpufreq core cleanups on top of the previous changes allowing it to
           preseve its sysfs directories over system suspend/resume (Viresh
           Kumar, Rafael J Wysocki, Sebastian Andrzej Siewior).
      
         - cpufreq fixes and cleanups related to governors (Viresh Kumar).
      
         - cpufreq updates (core and the cpufreq-dt driver) related to the
           turbo/boost mode support (Viresh Kumar, Bartlomiej Zolnierkiewicz).
      
         - New DT bindings for Operating Performance Points (OPP), support for
           them in the OPP framework and in the cpufreq-dt driver plus related
           OPP framework fixes and cleanups (Viresh Kumar).
      
         - cpufreq powernv driver updates (Shilpasri G Bhat).
      
         - New cpufreq driver for Mediatek MT8173 (Pi-Cheng Chen).
      
         - Assorted cpufreq driver (speedstep-lib, sfi, integrator) cleanups
           and fixes (Abhilash Jindal, Andrzej Hajda, Cristian Ardelean).
      
         - intel_pstate driver updates including Skylake-S support, support
           for enabling HW P-states per CPU and an additional vendor bypass
           list entry (Kristen Carlson Accardi, Chen Yu, Ethan Zhao).
      
         - cpuidle core fixes related to the handling of coupled idle states
           (Xunlei Pang).
      
         - intel_idle driver updates including Skylake Client support and
           support for freeze-mode-specific idle states (Len Brown).
      
         - Driver core updates related to power management (Andy Shevchenko,
           Rafael J Wysocki).
      
         - Generic power domains framework fixes and cleanups (Jon Hunter,
           Geert Uytterhoeven, Rajendra Nayak, Ulf Hansson).
      
         - Device PM QoS framework update to allow the latency tolerance
           setting to be exposed to user space via sysfs (Mika Westerberg).
      
         - devfreq support for PPMUv2 in Exynos5433 and a fix for an incorrect
           exynos-ppmu DT binding (Chanwoo Choi, Javier Martinez Canillas).
      
         - System sleep support updates (Alan Stern, Len Brown, SungEun Kim).

      Linus Torvalds authored
      Pull user namespace updates from Eric Biederman:
       "This finishes up the changes to ensure proc and sysfs do not start
        implementing executable files, as the there are application today that
        are only secure because such files do not exist.
      
        It akso fixes a long standing misfeature of /proc/<pid>/mountinfo that
        did not show the proper source for files bind mounted from
        /proc/<pid>/ns/*.
      
        It also straightens out the handling of clone flags related to user
        namespaces, fixing an unnecessary failure of unshare(CLONE_NEWUSER)
        when files such as /proc/<pid>/environ are read while <pid> is calling
        unshare.  This winds up fixing a minor bug in unshare flag handling
        that dates back to the first version of unshare in the kernel.
      
        Finally, this fixes a minor regression caused by the introduction of
        sysfs_create_mount_point, which broke someone's in house application,
        by restoring the size of /sys/fs/cgroup to 0 bytes.  Apparently that
        application uses the directory size to determine if a tmpfs is mounted
        on /sys/fs/cgroup.
      
        The bind mount escape fixes are present in Al Viros for-next branch.
        and I expect them to come from there.  The bind mount escape is the
        last of the user namespace related security bugs that I am aware of"

       "This updated pull request does not contain the last few GIC related
        patches which were reported to cause a regression.  There is a fix
        available, but I let it breed for a couple of days first.
      
        The irq departement provides:
      
         - new infrastructure to support non PCI based MSI interrupts
         - a couple of new irq chip drivers
         - the usual pile of fixlets and updates to irq chip drivers
         - preparatory changes for removal of the irq argument from interrupt
           flow handlers
         - preparatory changes to remove IRQF_VALID"

        No less than twentythree thousand lines of additions! Just imagine the

        hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
        UniPhier hardware!
      
        For those of you feeling less adventurous, added hardware support on

        of your liking.

         - Rockchip veyron (Chromebook) support, as well as several other new boards

      Wall time obtained from do_gettimeofday is susceptible to sudden jumps due to

      Monotonic time is constantly increasing time better suited for comparing two
