      Pull EFI updates from Ingo Molnar:
       "Main changes in this cycle were:
      
         - Refactor the EFI memory map code into architecture neutral files
           and allow drivers to permanently reserve EFI boot services regions
           on x86, as well as ARM/arm64. (Matt Fleming)
      
         - Add ARM support for the EFI ESRT driver. (Ard Biesheuvel)
      
         - Make the EFI runtime services and efivar API interruptible by
           swapping spinlocks for semaphores. (Sylvain Chouleur)
      
         - Provide the EFI identity mapping for kexec which allows kexec to
           work on SGI/UV platforms with requiring the "noefi" kernel command
           line parameter. (Alex Thorlton)
      
         - Add debugfs node to dump EFI page tables on arm64. (Ard Biesheuvel)
      
         - Merge the EFI test driver being carried out of tree until now in
           the FWTS project. (Ivan Hu)
      
         - Expand the list of flags for classifying EFI regions as "RAM" on
           arm64 so we align with the UEFI spec. (Ard Biesheuvel)
      
         - Optimise out the EFI mixed mode if it's unsupported (CONFIG_X86_32)
           or disabled (CONFIG_EFI_MIXED=n) and switch the early EFI boot
           services function table for direct calls, alleviating us from
           having to maintain the custom function table. (Lukas Wunner)
      
         - Miscellaneous cleanups and fixes"

      Linus Torvalds authored
      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)"

      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)"

      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).

         - Roger noticed that dma_max_pfn() was calculating the upper limit
           wrongly, by adding the PFN offset of memory twice.
      
         - A fix from Robin to correct parsing of MPIDR values when the
           address size is larger than one BE32 unit.
      
         - A fix from Srinivas to ensure that we do not rely on the boot
           loader (or previous Linux kernel) setting the translation table
           base register a certain way in the decompressor, which can lead to

      ARM: 8618/1: decompressor: reset ttbcr fields to use TTBR0 on ARMv7 · 117e5e9c
      Srinivas Ramana authored
      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 dbece458 ("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.

      MIPS: CM: Fix mips_cm_max_vp_width for non-MT kernels on MT systems · 6605d156
      Paul Burton authored
      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.

      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"
