Pull ACPI updates from Rafael Wysocki:
 "First off, the ACPICA code in the kernel is updated to upstream
  revision 20160831 that brings in a few bug fixes and cleanups. In
  particular, it is possible to mask GPEs now (and the sysfs interface
  for GPE control is fixed on top of that), problems related to the
  table loading mechanism are fixed and all code related to FADT version
  2 (which has never been part of the ACPI specification) is dropped.

  On the new features front, there is a new watchdog driver based on the
  ACPI WDAT (ACPI Watchdog Action Table), needed on some platforms to
  replace the iTCO watchdog that doesn't work there, and some UART
  devices get new definitions of built-in properties (to be accessed via
  the generic device properties API).

  Also, included is a fix for an ACPI-related PCI resorces allocation
  issue and a few problems in the EC driver and in the button and
  battery drivers are fixed.

  In addition to that, the ACPI CPPC library is updated to make batching
  of requests sent over the PCC channel possible (which reduces the PCC
  usage overhead substantially in some cases) and to support functional
  fixed hardware (FFH) type of CPPC registers access (which will allow
  CPPC to be used on x86 too in the future).

  As usual, there are some assorted fixes and cleanups too.

  Specifics:

   - Update of the ACPICA code in the kernel to upstream revision
     20160831 with the following major changes:

      * New mechanism for GPE masking.
      * Fixes for issues related to the LoadTable operator and table
        loading.
      * Fixes for issues related to so-called module-level code (MLC),
        that is AML that doesn't belong to any methods.
      * Change of the return value of the _OSI method to reflect the
        Windows behavior.
      * GAS (Generic Address Structure) support fix related to 32-bit
        FADT addresses.
      * Elimination of unnecessary FADT version 2 support.
      * ACPI tools fixes and cleanups.

     From Bob Moore, Lv Zheng, and Jung-uk Kim.

   - ACPI sysfs interface updates to fix GPE handling (on top of the new
     GPE masking mechanism in ACPICA) and issues related to table
     loading (Lv Zheng).

   - New watchdog driver based on the ACPI WDAT (ACPI Watchdog Action
     Table), needed on some platforms to replace the iTCO watchdog that
     doesn't work there and related updates of the intel_pmc_ipc,
     i2c/i801 and MFD/lcp_ich drivers (Mika Westerberg).

   - Driver core fix to prevent it from leaking secondary fwnode objects
     during device removal (Lukas Wunner).

   - New definitions of built-in properties for UART in ACPI-based x86
     SoC drivers and a 8250_dw driver quirk for the APM X-Gene SoC
     (Heikki Krogerus).

   - New device ID for the Vulcan SPI controller and constification of
     local strucures in the AMD SoC (APD) ACPI driver (Kamlakant Patel,
     Julia Lawall).

   - Fix for a bug causing the allocation of PCI resorces to fail if
     ACPI-enumerated child platform devices are registered below the PCI
     devices in question (Mika Westerberg).

   - Change of the default polarity for PCI legacy IRQs to high on
     systems booting wth ACPI on platforms with a GIC interrupt
     controller model fixing the discrepancy between the specification
     and HW behavior (Lorenzo Pieralisi).

   - Fixes for the handling of system suspend/resume in the ACPI EC
     driver and update of that driver to make it cope with the cases
     when the EC device defined in the ECDT has to be used throughout
     the entire system life cycle (Lv Zheng).

   - Update of the ACPI CPPC library to allow it to batch requests sent
     over the PCC channel (to reduce overhead), to support the fixed
     functional hardware (FFH) CPPC registers access type, to notify the
     mailbox framework about TX completions when the interrupt flag is
     set for the PCC mailbox, and to support HW-Reduced Communication
     Subspace type 2 (Ashwin Chaugule, Prashanth Prakash, Srinivas
     Pandruvada, Hoan Tran).

   - ACPI button driver fix and documentation update related to the
     handling of laptop lids (Lv Zheng).

   - ACPI battery driver initialization fix (Carlos Garnacho).

   - ACPI GPIO enumeration documentation update (Mika Westerberg).

   - Assorted updates of the core ACPI bus type code (Lukas Wunner, Lv
     Zheng).

   - Assorted cleanups of the ACPI table parsing code and the
     x86-specific ACPI code (Al Stone).

   - Fixes for assorted ACPI-related issues found in linux-next (Wei
     Yongjun)"

Linus Torvalds 72ec94560d Merge tag 'pm-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki:
 "Traditionally, cpufreq is the area with the greatest number of
  changes, but there are fewer of them than last time. There also is
  some activity in the generic power domains and the devfreq frameworks,
  a couple of system suspend and hibernation fixes and some assorted
  changes in other places.

  One new feature is the cpufreq change to allow the scheduler to pass
  hints to the governors' utilization update callbacks and some code
  rework based on that. Another one is the support for domain removal in
  the generic power domains framework. Also it is now possible to use
  hibernation with PAGE_POISONING_ZERO enabled and devfreq supports the
  RockChip DFI controller and the rk3399 DMC.

  The rest of the changes is mostly fixes and cleanups in a number of
  places.

  Specifics:

   - Add a mechanism for passing hints from the scheduler to cpufreq
     governors via their utilization update callbacks and use it to
     introduce "IOwait boosting" into the schedutil governor and
     intel_pstate that will make them boost performance if the enqueued
     task was previously waiting on I/O (Rafael Wysocki).

   - Fix a schedutil governor problem that causes it to overestimate
     utilization if SMT is in use (Steve Muckle).

   - Update defconfigs trying to use the schedutil governor as a module
     which is not possible any more (Javier Martinez Canillas).

   - Update the intel_pstate's pstate_sample tracepoint to take "IOwait
     boosting" into account (Srinivas Pandruvada).

   - Fix a problem in the cpufreq core causing it to mishandle the
     initialization of CPUs registered after the cpufreq driver (Viresh
     Kumar, Rafael Wysocki).

   - Make the cpufreq-dt driver support per-policy governor tunables,
     clean it up and update its Kconfig description (Viresh Kumar).

   - Add support for more ARM platforms to the cpufreq-dt driver
     (Chanwoo Choi, Dave Gerlach, Geert Uytterhoeven).

   - Make the cpufreq CPPC driver report frequencies in KHz to avoid
     user space compatiblility issues (Al Stone, Hoan Tran).

   - Clean up a few cpufreq drivers (st, kirkwood, SCPI) a bit (Colin
     Ian King, Markus Elfring).

   - Constify some local structures in the intel_pstate driver (Julia
     Lawall).

   - Add a Documentation/cpu-freq/ entry to MAINTAINERS (Jean Delvare).

   - Add support for PM domain removal to the generic power domains
     (genpd) framework, add new DT helper functions to it and make it
     always enable debugfs support if available (Jon Hunter, Tomeu
     Vizoso).

   - Clean up the generic power domains (genpd) framework and make it
     avoid measuring power-on and power-off latencies during system-wide
     PM transitions (Ulf Hansson).

   - Add support for the RockChip DFI controller and the rk3399 DMC to
     the devfreq framework (Lin Huang, Axel Lin, Arnd Bergmann).

   - Add COMPILE_TEST to the devfreq framework (Krzysztof Kozlowski,
     Stephen Rothwell).

   - Fix a minor issue in the exynos-ppmu devfreq driver and fix up
     devfreq Kconfig indentation style (Wei Yongjun, Jisheng Zhang).

   - Fix the system suspend interface to make suspend-to-idle work if
     platform suspend operations have not been registered (Sudeep
     Holla).

   - Make it possible to use hibernation with PAGE_POISONING_ZERO
     enabled (Anisse Astier).

   - Increas the default timeout of the system suspend/resume watchdog
     and make it depend on EXPERT (Chen Yu).

   - Make the operating performance points (OPP) framework avoid using
     OPPs that aren't supported by the platform and fix a build warning
     in it (Dave Gerlach, Arnd Bergmann).

   - Fix the ARM cpuidle driver's return value (Christophe Jaillet).

   - Make the SmartReflex AVS (Adaptive Voltage Scaling) driver use more
     common logging style (Joe Perches)"

Linus Torvalds 7af8a0f808 Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
 "It's a bit all over the place this time with no "killer feature" to
  speak of.  Support for mismatched cache line sizes should help people
  seeing whacky JIT failures on some SoCs, and the big.LITTLE perf
  updates have been a long time coming, but a lot of the changes here
  are cleanups.

  We stray outside arch/arm64 in a few areas: the arch/arm/ arch_timer
  workaround is acked by Russell, the DT/OF bits are acked by Rob, the
  arch_timer clocksource changes acked by Marc, CPU hotplug by tglx and
  jump_label by Peter (all CC'd).

  Summary:

   - Support for execute-only page permissions
   - Support for hibernate and DEBUG_PAGEALLOC
   - Support for heterogeneous systems with mismatches cache line sizes
   - Errata workarounds (A53 843419 update and QorIQ A-008585 timer bug)
   - arm64 PMU perf updates, including cpumasks for heterogeneous systems
   - Set UTS_MACHINE for building rpm packages
   - Yet another head.S tidy-up
   - Some cleanups and refactoring, particularly in the NUMA code

 "Three relatively small fixes for ARM:

   - A fix from Srinivas to ensure that we do not rely on the boot

Srinivas Ramana 117e5e9c4c ARM: 8618/1: decompressor: reset ttbcr fields to use TTBR0 on ARMv7
If the bootloader uses the long descriptor format and jumps to
kernel decompressor code, TTBCR may not be in a right state.
Before enabling the MMU, it is required to clear the TTBCR.PD0
field to use TTBR0 for translation table walks.

The commit dbece45894 ("ARM: 7501/1: decompressor:
reset ttbcr for VMSA ARMv7 cores") does the reset of TTBCR.N, but
doesn't consider all the bits for the size of TTBCR.N.

Clear TTBCR.PD0 field and reset all the three bits of TTBCR.N to
indicate the use of TTBR0 and the correct base address width.

Paul Burton 6605d156bd MIPS: CM: Fix mips_cm_max_vp_width for non-MT kernels on MT systems
When discovering the number of VPEs per core, smp_num_siblings will be
incorrect for kernels built without support for the MIPS MultiThreading
(MT) ASE running on systems which implement said ASE. This leads to
accesses to VPEs in secondary cores being performed incorrectly since
mips_cm_vp_id calculates the wrong ID to write to the local "other"
registers. Fix this by examining the number of VPEs in the core as
reported by the CM.

This patch presumes that the number of VPEs will be the same in each
core of the system. As this path only applies to systems with CM version
2.5 or lower, and this property is true of all such known systems, this
is likely to be fine but is described in a comment for good measure.

Linus Torvalds f51fdffad5 Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fix from James Bottomley:
 "One final fix before 4.8.

  There was a memory leak triggered by turning scsi mq off due to the
  fact that we assume on host release that the already running hosts
  weren't mq based because that's the state of the global flag (even
  though they were).

  Fix it by tracking this on a per host host basis"
