      Pull power management and ACPI updates from Rafael Wysocki:
       "This time the majority of changes go into cpufreq and they are
        significant.
      
        First off, the way CPU frequency updates are triggered is different
        now.  Instead of having to set up and manage a deferrable timer for
        each CPU in the system to evaluate and possibly change its frequency
        periodically, cpufreq governors set up callbacks to be invoked by the
        scheduler on a regular basis (basically on utilization updates).  The
        "old" governors, "ondemand" and "conservative", still do all of their
        work in process context (although that is triggered by the scheduler
        now), but intel_pstate does it all in the callback invoked by the
        scheduler with no need for any additional asynchronous processing.
      
        Of course, this eliminates the overhead related to the management of
        all those timers, but also it allows the cpufreq governor code to be
        simplified quite a bit.  On top of that, the common code and data
        structures used by the "ondemand" and "conservative" governors are
        cleaned up and made more straightforward and some long-standing and
        quite annoying problems are addressed.  In particular, the handling of
        governor sysfs attributes is modified and the related locking becomes
        more fine grained which allows some concurrency problems to be avoided
        (particularly deadlocks with the core cpufreq code).
      
        In principle, the new mechanism for triggering frequency updates
        allows utilization information to be passed from the scheduler to
        cpufreq.  Although the current code doesn't make use of it, in the
        works is a new cpufreq governor that will make decisions based on the
        scheduler's utilization data.  That should allow the scheduler and
        cpufreq to work more closely together in the long run.
      
        In addition to the core and governor changes, cpufreq drivers are
        updated too.  Fixes and optimizations go into intel_pstate, the
        cpufreq-dt driver is updated on top of some modification in the
        Operating Performance Points (OPP) framework and there are fixes and
        other updates in the powernv cpufreq driver.
      
        Apart from the cpufreq updates there is some new ACPICA material,
        including a fix for a problem introduced by previous ACPICA updates,
        and some less significant changes in the ACPI code, like CPPC code
        optimizations, ACPI processor driver cleanups and support for loading
        ACPI tables from initrd.
      
        Also updated are the generic power domains framework, the Intel RAPL
        power capping driver and the turbostat utility and we have a bunch of
        traditional assorted fixes and cleanups.
      
        Specifics:
      
         - Redesign of cpufreq governors and the intel_pstate driver to make
           them use callbacks invoked by the scheduler to trigger CPU
           frequency evaluation instead of using per-CPU deferrable timers for
           that purpose (Rafael Wysocki).
      
         - Reorganization and cleanup of cpufreq governor code to make it more
           straightforward and fix some concurrency problems in it (Rafael
           Wysocki, Viresh Kumar).
      
         - Cleanup and improvements of locking in the cpufreq core (Viresh
           Kumar).
      
         - Assorted cleanups in the cpufreq core (Rafael Wysocki, Viresh
           Kumar, Eric Biggers).
      
         - intel_pstate driver updates including fixes, optimizations and a
           modification to make it enable enable hardware-coordinated P-state
           selection (HWP) by default if supported by the processor (Philippe
           Longepe, Srinivas Pandruvada, Rafael Wysocki, Viresh Kumar, Felipe
           Franciosi).
      
         - Operating Performance Points (OPP) framework updates to improve its
           handling of voltage regulators and device clocks and updates of the
           cpufreq-dt driver on top of that (Viresh Kumar, Jon Hunter).
      
         - Updates of the powernv cpufreq driver to fix initialization and
           cleanup problems in it and correct its worker thread handling with
           respect to CPU offline, new powernv_throttle tracepoint (Shilpasri
           Bhat).
      
         - ACPI cpufreq driver optimization and cleanup (Rafael Wysocki).
      
         - ACPICA updates including one fix for a regression introduced by
           previos changes in the ACPICA code (Bob Moore, Lv Zheng, David Box,
           Colin Ian King).
      
         - Support for installing ACPI tables from initrd (Lv Zheng).
      
         - Optimizations of the ACPI CPPC code (Prashanth Prakash, Ashwin
           Chaugule).
      
         - Support for _HID(ACPI0010) devices (ACPI processor containers) and
           ACPI processor driver cleanups (Sudeep Holla).
      
         - Support for ACPI-based enumeration of the AMBA bus (Graeme Gregory,
           Aleksey Makarov).
      
         - Modification of the ACPI PCI IRQ management code to make it treat
           255 in the Interrupt Line register as "not connected" on x86 (as
           per the specification) and avoid attempts to use that value as a
           valid interrupt vector (Chen Fan).
      
         - ACPI APEI fixes related to resource leaks (Josh Hunt).
      
         - Removal of modularity from a few ACPI drivers (BGRT, GHES,
           intel_pmic_crc) that cannot be built as modules in practice (Paul
           Gortmaker).
      
         - PNP framework update to make it treat ACPI_RESOURCE_TYPE_SERIAL_BUS
           as a valid resource type (Harb Abdulhamid).
      
         - New device ID (future AMD I2C controller) in the ACPI driver for
           AMD SoCs (APD) and in the designware I2C driver (Xiangliang Yu).
      
         - Assorted ACPI cleanups (Colin Ian King, Kaiyen Chang, Oleg Drokin).
      
         - cpuidle menu governor optimization to avoid a square root
           computation in it (Rasmus Villemoes).
      
         - Fix for potential use-after-free in the generic device properties
           framework (Heikki Krogerus).
      
         - Updates of the generic power domains (genpd) framework including
           support for multiple power states of a domain, fixes and debugfs
           output improvements (Axel Haslam, Jon Hunter, Laurent Pinchart,
           Geert Uytterhoeven).
      
         - Intel RAPL power capping driver updates to reduce IPI overhead in
           it (Jacob Pan).
      
         - System suspend/hibernation code cleanups (Eric Biggers, Saurabh
           Sengar).
      
         - Year 2038 fix for the process freezer (Abhilash Jindal).
      
         - turbostat utility updates including new features (decoding of more
           registers and CPUID fields, sub-second intervals support, GFX MHz
           and RC6 printout, --out command line option), fixes (syscall jitter
           detection and workaround, reductioin of the number of syscalls
           made, fixes related to Xeon x200 processors, compiler warning
           fixes) and cleanups (Len Brown, Hubert Chrzaniuk, Chen Yu)"

       "One of the largest releases for KVM...  Hardly any generic
        changes, but lots of architecture-specific updates.
      
        ARM:
         - VHE support so that we can run the kernel at EL2 on ARMv8.1 systems
         - PMU support for guests
         - 32bit world switch rewritten in C
         - various optimizations to the vgic save/restore code.
      
        PPC:
         - enabled KVM-VFIO integration ("VFIO device")
         - optimizations to speed up IPIs between vcpus
         - in-kernel handling of IOMMU hypercalls
         - support for dynamic DMA windows (DDW).
      
        s390:
         - provide the floating point registers via sync regs;
         - separated instruction vs.  data accesses
         - dirty log improvements for huge guests
         - bugfixes and documentation improvements.
      
        x86:
         - Hyper-V VMBus hypercall userspace exit
         - alternative implementation of lowest-priority interrupts using
           vector hashing (for better VT-d posted interrupt support)
         - fixed guest debugging with nested virtualizations
         - improved interrupt tracking in the in-kernel IOAPIC
         - generic infrastructure for tracking writes to guest
           memory - currently its only use is to speedup the legacy shadow
           paging (pre-EPT) case, but in the future it will be used for
           virtual GPUs as well
         - much cleanup (LAPIC, kvmclock, MMU, PIT), including ubsan fixes"

           fixes handling of explictly specified endianness on big endian
