      Pull power management updates from Rafael Wysocki:
       "The big ticket items here are the rework of suspend-to-idle in order
        to add proper support for power button wakeup from it on recent Dell
        laptops and the rework of interfaces exporting the current CPU
        frequency on x86.
      
        In addition to that, support for a few new pieces of hardware is
        added, the PCI/ACPI device wakeup infrastructure is simplified
        significantly and the wakeup IRQ framework is fixed to unbreak the IRQ
        bus locking infrastructure.
      
        Also, there are some functional improvements for intel_pstate, tools
        updates and small fixes and cleanups all over.
      
        Specifics:
      
         - Rework suspend-to-idle to allow it to take wakeup events signaled
           by the EC into account on ACPI-based platforms in order to properly
           support power button wakeup from suspend-to-idle on recent Dell
           laptops (Rafael Wysocki).
      
           That includes the core suspend-to-idle code rework, support for the
           Low Power S0 _DSM interface, and support for the ACPI INT0002
           Virtual GPIO device from Hans de Goede (required for USB keyboard
           wakeup from suspend-to-idle to work on some machines).
      
         - Stop trying to export the current CPU frequency via /proc/cpuinfo
           on x86 as that is inaccurate and confusing (Len Brown).
      
         - Rework the way in which the current CPU frequency is exported by
           the kernel (over the cpufreq sysfs interface) on x86 systems with
           the APERF and MPERF registers by always using values read from
           these registers, when available, to compute the current frequency
           regardless of which cpufreq driver is in use (Len Brown).
      
         - Rework the PCI/ACPI device wakeup infrastructure to remove the
           questionable and artificial distinction between "devices that can
           wake up the system from sleep states" and "devices that can
           generate wakeup signals in the working state" from it, which allows
           the code to be simplified quite a bit (Rafael Wysocki).
      
         - Fix the wakeup IRQ framework by making it use SRCU instead of RCU
           which doesn't allow sleeping in the read-side critical sections,
           but which in turn is expected to be allowed by the IRQ bus locking
           infrastructure (Thomas Gleixner).
      
         - Modify some computations in the intel_pstate driver to avoid
           rounding errors resulting from them (Srinivas Pandruvada).
      
         - Reduce the overhead of the intel_pstate driver in the HWP
           (hardware-managed P-states) mode and when the "performance" P-state
           selection algorithm is in use by making it avoid registering
           scheduler callbacks in those cases (Len Brown).
      
         - Rework the energy_performance_preference sysfs knob in intel_pstate
           by changing the values that correspond to different symbolic hint
           names used by it (Len Brown).
      
         - Make it possible to use more than one cpuidle driver at the same
           time on ARM (Daniel Lezcano).
      
         - Make it possible to prevent the cpuidle menu governor from using
           the 0 state by disabling it via sysfs (Nicholas Piggin).
      
         - Add support for FFH (Fixed Functional Hardware) MWAIT in ACPI C1 on
           AMD systems (Yazen Ghannam).
      
         - Make the CPPC cpufreq driver take the lowest nonlinear performance
           information into account (Prashanth Prakash).
      
         - Add support for hi3660 to the cpufreq-dt driver, fix the imx6q
           driver and clean up the sfi, exynos5440 and intel_pstate drivers
           (Colin Ian King, Krzysztof Kozlowski, Octavian Purdila, Rafael
           Wysocki, Tao Wang).
      
         - Fix a few minor issues in the generic power domains (genpd)
           framework and clean it up somewhat (Krzysztof Kozlowski, Mikko
           Perttunen, Viresh Kumar).
      
         - Fix a couple of minor issues in the operating performance points
           (OPP) framework and clean it up somewhat (Viresh Kumar).
      
         - Fix a CONFIG dependency in the hibernation core and clean it up
           slightly (Balbir Singh, Arvind Yadav, BaoJun Luo).
      
         - Add rk3228 support to the rockchip-io adaptive voltage scaling
           (AVS) driver (David Wu).
      
         - Fix an incorrect bit shift operation in the RAPL power capping
           driver (Adam Lessnau).
      
         - Add support for the EPP field in the HWP (hardware managed
           P-states) control register, HWP.EPP, to the x86_energy_perf_policy
           tool and update msr-index.h with HWP.EPP values (Len Brown).
      
         - Fix some minor issues in the turbostat tool (Len Brown).
      
         - Add support for AMD family 0x17 CPUs to the cpupower tool and fix a
           minor issue in it (Sherry Hurwitz).
      
         - Assorted cleanups, mostly related to the constification of some
           data structures (Arvind Yadav, Joe Perches, Kees Cook, Krzysztof
           Kozlowski)"

        This feature has been on the cards since the subsystem was originally

        and finally implemented it.
      
         - SPI slave support, together with wholesale renaming of SPI
           controllers from master to controller which went surprisingly

      Pull SMP hotplug updates from Thomas Gleixner:
       "This update is primarily a cleanup of the CPU hotplug locking code.
      
        The hotplug locking mechanism is an open coded RWSEM, which allows
        recursive locking. The main problem with that is the recursive nature
        as it evades the full lockdep coverage and hides potential deadlocks.
      
        The rework replaces the open coded RWSEM with a percpu RWSEM and
        establishes full lockdep coverage that way.
      
        The bulk of the changes fix up recursive locking issues and address
        the now fully reported potential deadlocks all over the place. Some of
        these deadlocks have been observed in the RT tree, but on mainline the

      Pull x86 PCI updates from Thomas Gleixner:
       "This update provides the seperation of x86 PCI accessors from the
        global PCI lock in the generic PCI config space accessors.
      
        The reasons for this are:
      
         - x86 has it's own PCI config lock for various reasons, so the
           accessors have to lock two locks nested.
      
         - The ECAM (mmconfig) access to the extended configuration space does
           not require locking. The existing generic locking causes a massive
           lock contention when accessing the extended config space of the
           Uncore facility for performance monitoring.
      
        The commit which switched the access to the primary config space over
        to ECAM mode has been removed from the branch, so the primary config
        space is still accessed with type1 accessors properly serialized by
        the x86 internal locking.
      
        Bjorn agreed on merging this through the x86 tree"

       "The irq department delivers:
      
         - Expand the generic infrastructure handling the irq migration on CPU
           hotplug and convert X86 over to it. (Thomas Gleixner)
      
           Aside of consolidating code this is a preparatory change for:
      
         - Finalizing the affinity management for multi-queue devices. The
           main change here is to shut down interrupts which are affine to a
           outgoing CPU and reenabling them when the CPU comes online again.
           That avoids moving interrupts pointlessly around and breaking and
           reestablishing affinities for no value. (Christoph Hellwig)
      
           Note: This contains also the BLOCK-MQ and NVME changes which depend
           on the rework of the irq core infrastructure. Jens acked them and
           agreed that they should go with the irq changes.

      Pull scheduler updates from Ingo Molnar:
       "The main changes in this cycle were:
      
         - Add the SYSTEM_SCHEDULING bootup state to move various scheduler
           debug checks earlier into the bootup. This turns silent and
           sporadically deadly bugs into nice, deterministic splats. Fix some
           of the splats that triggered. (Thomas Gleixner)
      
         - A round of restructuring and refactoring of the load-balancing and
           topology code (Peter Zijlstra)
      
         - Another round of consolidating ~20 of incremental scheduler code
           history: this time in terms of wait-queue nomenclature. (I didn't
           get much feedback on these renaming patches, and we can still
           easily change any names I might have misplaced, so if anyone hates
           a new name, please holler and I'll fix it.) (Ingo Molnar)
      
         - sched/numa improvements, fixes and updates (Rik van Riel)
      
         - Another round of x86/tsc scheduler clock code improvements, in hope
           of making it more robust (Peter Zijlstra)
      
         - Improve NOHZ behavior (Frederic Weisbecker)
      
         - Deadline scheduler improvements and fixes (Luca Abeni, Daniel
           Bristot de Oliveira)
      
         - Simplify and optimize the topology setup code (Lauro Ramos
           Venancio)
      
         - Debloat and decouple scheduler code some more (Nicolas Pitre)
      
         - Simplify code by making better use of llist primitives (Byungchul
           Park)
