Pull power management and ACPI updates from Rafael Wysocki:
 "Quite a new features are included this time.

  First off, the Collaborative Processor Performance Control interface
  (version 2) defined by ACPI will now be supported on ARM64 along with
  a cpufreq frontend for CPU performance scaling.

  Second, ACPI gets a new infrastructure for the early probing of IRQ
  chips and clock sources (along the lines of the existing similar
  mechanism for DT).

  Next, the ACPI core and the generic device properties API will now
  support a recently introduced hierarchical properties extension of the
  _DSD (Device Specific Data) ACPI device configuration object.  If the
  ACPI platform firmware uses that extension to organize device
  properties in a hierarchical way, the kernel will automatically handle
  it and make those properties available to device drivers via the
  generic device properties API.

  It also will be possible to build the ACPICA's AML interpreter
  debugger into the kernel now and use that to diagnose AML-related
  problems more efficiently.  In the future, this should make it
  possible to single-step AML execution and do similar things.
  Interesting stuff, although somewhat experimental at this point.

  Finally, the PM core gets a new mechanism that can be used by device
  drivers to distinguish between suspend-to-RAM (based on platform
  firmware support) and suspend-to-idle (or other variants of system
  suspend the platform firmware is not involved in) and possibly
  optimize their device suspend/resume handling accordingly.

  In addition to that, some existing features are re-organized quite
  substantially.

  First, the ACPI-based handling of PCI host bridges on x86 and ia64 is
  unified and the common code goes into the ACPI core (so as to reduce
  code duplication and eliminate non-essential differences between the
  two architectures in that area).

  Second, the Operating Performance Points (OPP) framework is
  reorganized to make the code easier to find and follow.

  Next, the cpufreq core's sysfs interface is reorganized to get rid of
  the "primary CPU" concept for configurations in which the same
  performance scaling settings are shared between multiple CPUs.

  Finally, some interfaces that aren't necessary any more are dropped
  from the generic power domains framework.

  On top of the above we have some minor extensions, cleanups and bug
  fixes in multiple places, as usual.

  Specifics:

   - ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng).

     The most significant change is to allow the AML debugger to be
     built into the kernel.  On top of that there is an update related
     to the NFIT table (the ACPI persistent memory interface) and a few
     fixes and cleanups.

   - ACPI CPPC2 (Collaborative Processor Performance Control v2) support
     along with a cpufreq frontend (Ashwin Chaugule).

     This can only be enabled on ARM64 at this point.

   - New ACPI infrastructure for the early probing of IRQ chips and
     clock sources (Marc Zyngier).

   - Support for a new hierarchical properties extension of the ACPI
     _DSD (Device Specific Data) device configuration object allowing
     the kernel to handle hierarchical properties (provided by the
     platform firmware this way) automatically and make them available
     to device drivers via the generic device properties interface
     (Rafael Wysocki).

   - Generic device properties API extension to obtain an index of
     certain string value in an array of strings, along the lines of
     of_property_match_string(), but working for all of the supported
     firmware node types, and support for the "dma-names" device
     property based on it (Mika Westerberg).

   - ACPI core fix to parse the MADT (Multiple APIC Description Table)
     entries in the order expected by platform firmware (and mandated by
     the specification) to avoid confusion on systems with more than 255
     logical CPUs (Lukasz Anaczkowski).

   - Consolidation of the ACPI-based handling of PCI host bridges on x86
     and ia64 (Jiang Liu).

   - ACPI core fixes to ensure that the correct IRQ number is used to
     represent the SCI (System Control Interrupt) in the cases when it
     has been re-mapped (Chen Yu).

   - New ACPI backlight quirk for Lenovo IdeaPad S405 (Hans de Goede).

   - ACPI EC driver fixes (Lv Zheng).

   - Assorted ACPI fixes and cleanups (Dan Carpenter, Insu Yun, Jiri
     Kosina, Rami Rosen, Rasmus Villemoes).

   - New mechanism in the PM core allowing drivers to check if the
     platform firmware is going to be involved in the upcoming system
     suspend or if it has been involved in the suspend the system is
     resuming from at the moment (Rafael Wysocki).

     This should allow drivers to optimize their suspend/resume handling
     in some cases and the changes include a couple of users of it (the
     i8042 input driver, PCI PM).

   - PCI PM fix to prevent runtime-suspended devices with PME enabled
     from being resumed during system suspend even if they aren't
     configured to wake up the system from sleep (Rafael Wysocki).

   - New mechanism to report the number of a wakeup IRQ that woke up the
     system from sleep last time (Alexandra Yates).

   - Removal of unused interfaces from the generic power domains
     framework and fixes related to latency measurements in that code
     (Ulf Hansson, Daniel Lezcano).

   - cpufreq core sysfs interface rework to make it handle CPUs that
     share performance scaling settings (represented by a common cpufreq
     policy object) more symmetrically (Viresh Kumar).

     This should help to simplify the CPU offline/online handling among
     other things.

   - cpufreq core fixes and cleanups (Viresh Kumar).

   - intel_pstate fixes related to the Turbo Activation Ratio (TAR)
     mechanism on client platforms which causes the turbo P-states range
     to vary depending on platform firmware settings (Srinivas
     Pandruvada).

   - intel_pstate sysfs interface fix (Prarit Bhargava).

   - Assorted cpufreq driver (imx, tegra20, powernv, integrator) fixes
     and cleanups (Bai Ping, Bartlomiej Zolnierkiewicz, Shilpasri G
     Bhat, Luis de Bethencourt).

   - cpuidle mvebu driver cleanups (Russell King).

   - OPP (Operating Performance Points) framework code reorganization to
     make it more maintainable (Viresh Kumar).

   - Intel Broxton support for the RAPL (Running Average Power Limits)
     power capping driver (Amy Wiles).

   - Assorted power management code fixes and cleanups (Dan Carpenter,
     Geert Uytterhoeven, Geliang Tang, Luis de Bethencourt, Rasmus
     Villemoes)"
