       "The main changes in this cycle were:
      
         - Add support for the "Dhyana" x86 CPUs by Hygon: these are licensed
           based on the AMD Zen architecture, and are built and sold in China,
           for domestic datacenter use. The code is pretty close to AMD
           support, mostly with a few quirks and enumeration differences. (Pu
           Wen)
      
         - Enable CPUID support on Cyrix 6x86/6x86L processors"

         - Implement counter freezing for Arch Perfmon v4 (Skylake and newer).
           This allows to speed up the PMI handler by avoiding unnecessary MSR
           writes and make it more accurate. (Andi Kleen)

           and s390 to optimize jump labels (Ard Biesheuvel, Heiko Carstens)
      
         - Be a lot less permissive on weird (kernel address) uaccess faults
           on x86: BUG() when uaccess helpers fault on kernel addresses (Jann
           Horn)

      Linus Torvalds authored
      Pull RCU updates from Ingo Molnar:
       "The biggest change in this cycle is the conclusion of the big
        'simplify RCU to two primary flavors' consolidation work - i.e.
        there's a single RCU flavor for any kernel variant (PREEMPT and
        !PREEMPT):
      
          - Consolidate the RCU-bh, RCU-preempt, and RCU-sched flavors into a
            single flavor similar to RCU-sched in !PREEMPT kernels and into a
            single flavor similar to RCU-preempt (but also waiting on
            preempt-disabled sequences of code) in PREEMPT kernels.
      
            This branch also includes a refactoring of
            rcu_{nmi,irq}_{enter,exit}() from Byungchul Park.
      
          - Now that there is only one RCU flavor in any given running kernel,
            the many "rsp" pointers are no longer required, and this cleanup
            series removes them.
      
          - This branch carries out additional cleanups made possible by the
            RCU flavor consolidation, including inlining now-trivial
            functions, updating comments and definitions, and removing
            now-unneeded rcutorture scenarios.
      
          - Now that there is only one flavor of RCU in any running kernel,
            there is also only on rcu_data structure per CPU. This means that
            the rcu_dynticks structure can be merged into the rcu_data
            structure, a task taken on by this branch. This branch also
            contains a -rt-related fix from Mike Galbraith.
      
        There were also other updates:
      
          - Documentation updates, including some good-eye catches from Joel
            Fernandes.
      
          - SRCU updates, most notably changes enabling call_srcu() to be
            invoked very early in the boot sequence.
      
          - Torture-test updates, including some preliminary work towards
            making rcutorture better able to find problems that result in
            insufficient grace-period forward progress.
      
          - Initial changes to RCU to better promote forward progress of grace
            periods, including fixing a bug found by Marius Hillenbrand and
            David Woodhouse, with the fix suggested by Peter Zijlstra"

       "These fix ACPICA issues related to the handling of module-level AML,
        fix an ordering issue during ACPI initialization, update ACPICA to
        upstream revision 20181003 (including fixes mostly), fix issues with
        system-wide suspend/resume related to the ACPI driver for Intel SoCs
        (LPSS), fix device enumeration issues on boards with Dollar Cove or
        Whiskey Cove Intel PMICs, prevent ACPICA from calling ktime_get() in
        unsuitable conditions, update a few drivers and clean up some code in
        several places.
      
        Specifics:
      
         - Fix ACPICA issues related to the handling of module-level AML and
           make the ACPI initialization code parse ECDT before loading the

           enumeration problems on boards with Dollar Cove or Whiskey Cove
           Intel PMICs (Hans de Goede).
      
         - Prevent ACPICA from using ktime_get() during early resume from
           system-wide suspend before resuming the timekeeping which generally
           is unsafe and triggers a warning from the timekeeping code (Bart
           Van Assche).

           Device (TAD) driver (Rafael Wysocki).

       "These make hibernation on 32-bit x86 systems work in all of the cases
        in which it works on 64-bit x86 ones, update the menu cpuidle governor
        and the "polling" state to make them more efficient, add more hardware
        support to cpufreq drivers and fix issues with some of them, fix a bug
        in the conservative cpufreq governor, fix the operating performance
        points (OPP) framework and make it more stable, update the devfreq
        subsystem to take changes in the APIs used by into account and clean
        up some things all over.
      
        Specifics:
      
         - Backport hibernation bug fixes from x86-64 to x86-32 and
           consolidate hibernation handling on x86 to allow 32-bit systems to
           work in all of the cases in which 64-bit ones work (Zhimin Gu, Chen
           Yu).
      
         - Fix hibernation documentation (Vladimir D. Seleznev).
      
         - Update the menu cpuidle governor to fix a couple of issues with it,
           make it more efficient in some cases and clean it up (Rafael
           Wysocki).

           efficient (Rafael Wysocki).
      
         - Clean up the cpuidle core somewhat (Fieah Lim).
      
         - Fix the cpufreq conservative governor to take policy limits into
           account properly in some cases (Rafael Wysocki).
      
         - Add support for retrieving guaranteed performance information to
           the ACPI CPPC library and make the intel_pstate driver use it to
           expose the CPU base frequency via sysfs on systems with the
           hardware-managed P-states (HWP) feature enabled (Srinivas
           Pandruvada).

         - Get rid of device_node.name printing from cpufreq (Rob Herring).
      
         - Remove unnecessary unlikely() from the cpufreq core (Igor Stoppa).
      
         - Add support for the r8a7744 SoC to the cpufreq-dt driver (Biju
           Das).
      
         - Update the dt-platdev cpufreq driver to allow RK3399 to have
           separate tunables per cluster (Dmitry Torokhov).
      
         - Fix the dma_alloc_coherent() usage in the tegra186 cpufreq driver

           framework and make it more stable (Viresh Kumar, Dave Gerlach).
      
         - Update the devfreq subsystem to take changes in the APIs used by
           into account, fix some issues with it and make it stop print
           device_node.name directly (Bjorn Andersson, Enric Balletbo i Serra,
           Matthias Kaehlcke, Rob Herring, Vincent Donnefort, zhong jiang).
      
         - Prepare the generic power domains (genpd) framework for dealing
           with domains containing CPUs (Ulf Hansson).
      
         - Prevent sysfs attributes representing low-power S0 residency
           counters from being exposed if low-power S0 support is not
           indicated in ACPI FADT (Rajneesh Bhardwaj).
      
         - Get rid of custom CPU features macros for Intel CPUs from the
           intel_idle and RAPL drivers (Andy Shevchenko).
      
         - Update the tasks freezer to list tasks that refused to freeze and
           caused a system transition to a sleep state to be aborted (Todd
           Brandt).

      Linus Torvalds authored
      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.20 series:
      
        Core changes:
      
         - A patch series from Hans Verkuil to make it possible to
           enable/disable IRQs on a GPIO line at runtime and drive GPIO lines
           as output without having to put/get them from scratch.
      
           The irqchip callbacks have been improved so that they can use only
           the fastpatch callbacks to enable/disable irqs like any normal
           irqchip, especially the gpiod_lock_as_irq() has been improved to be
           callable in fastpath context.
      
           A bunch of rework had to be done to achieve this but it is a big
           win since I never liked to restrict this to slowpath. The only call
           requireing slowpath was try_module_get() and this is kept at the
           .request_resources() slowpath callback. In the GPIO CEC driver this
           is a big win sine a single line is used for both outgoing and
           incoming traffic, and this needs to use IRQs for incoming traffic
           while actively driving the line for outgoing traffic.
      
         - Janusz Krzysztofik improved the GPIO array API to pass a "cookie"
           (struct gpio_array) and a bitmap for setting or getting multiple
           GPIO lines at once.
      
           This improvement orginated in a specific need to speed up an OMAP1
           driver and has led to a much better API and real performance gains
           when the state of the array can be used to bypass a lot of checks
           and code when we want things to go really fast.
      
           The previous code would minimize the number of calls down to the
           driver callbacks assuming the CPU speed was orders of magnitude
           faster than the I/O latency, but this assumption was wrong on
           several platforms: what we needed to do was to profile and improve
           the speed on the hot path of the array functions and this change is
           now completed.
      
         - Clean out the painful and hard to grasp BNF experiments from the
           device tree bindings. Future approaches are looking into using JSON
           schema for this purpose. (Rob Herring is floating a patch series.)
      
        New drivers:
      
         - The RCAR driver now supports r8a774a1 (RZ/G2M).
      
         - Synopsys GPIO via CREGs driver.
      
        Major improvements:
      
         - Modernization of the EP93xx driver to use irqdomain and other
           contemporary concepts.
      
         - The ingenic driver has been merged into the Ingenic pin control
           driver and removed from the GPIO subsystem.
      
         - Debounce support in the ftgpio010 driver"

       "This is the bulk of pin control changes for the v4.20 series:
      
        There were no significant changes to the core this time! Bur the new
        Qualcomm, Mediatek and Broadcom drivers are quite interesting as they
        will be used in a few million embedded devices the coming years as it
        seems.
      
        New drivers:
      
         - Broadcom Northstar pin control driver.
      
         - Mediatek MT8183 subdriver.
      
         - Mediatek MT7623 subdriver.
      
         - Mediatek MT6765 subdriver.
      
         - Meson g12a subdriver.
      
         - Nuvoton NPCM7xx pin control and GPIO driver.
      
         - Qualcomm QCS404 pin control and GPIO subdriver.
      
         - Qualcomm SDM660 pin control and GPIO subdriver.
      
         - Renesas R8A7744 PFC subdriver.
      
         - Renesas R8A774C0 PFC subdriver.
      
         - Renesas RZ/N1 pinctrl driver
      
        Major improvements:
      
         - Pulled the GPIO support for Ingenic over from the GPIO subsystem
           and consolidated it all in the Ingenic pin control driver.
      
         - Major cleanups and consolidation work in all Intel drivers.
      
         - Major cleanups and consolidation work in all Mediatek drivers.
      
         - Lots of incremental improvements to the Renesas PFC pin controller
           family.
      
         - All drivers doing GPIO now include <linux/gpio/driver.h> and
           nothing else"

        Summary:
      
         - mostly more consolidation of the direct mapping code, including
           converting over hexagon, and merging the coherent and non-coherent
           code into a single dma_map_ops instance (me)
      
         - cleanups for the dma_configure/dma_unconfigure callchains (me)
      
         - better handling of dma_masks in odd setups (me, Alexander Duyck)
      
         - better debugging of passing vmalloc address to the DMA API (Stephen
           Boyd)
      
         - CMA command line parsing fix (He Zhe)"

      s390/pkey: move pckmo subfunction available checks away from module init · f822ad2c
      Harald Freudenberger authored
      The init of the pkey module currently fails if the pckmo instruction
      or the subfunctions are not available.  However, customers may
      restrict their LPAR to switch off exactly these functions and work
      with secure key only. So it is a valid case to have the pkey module
      active and use it for secure key to protected key transfer only.
      
      This patch moves the pckmo subfunction check from the pkey module init
      function into the internal function where the pckmo instruction is
      called. So now only on invocation of the pckmo instruction the check
      for the required subfunction is done. If not available EOPNOTSUPP is
      returned to the caller.
      
      The check for having the pckmo instruction available is still done
      during module init. This instruction came in with MSA 3 together with
      the basic set of kmc instructions needed to work with protected keys.

      When the kernel is built with:
      CONFIG_PREEMPT=y
      CONFIG_PREEMPT_COUNT=y
      "stfle" function used by kasan initialization code makes additional
      call to preempt_count_add/preempt_count_sub. To avoid removing kasan
      instrumentation from sched code where those functions leave split stfle
      function and provide __stfle variant without preemption handling to be
      used by Kasan.
