      Pull sound updates from Takashi Iwai:
       "As shown in diffstat and logs, it was again a busy development cycle
        at this time, too. The most significant changes are still on-going
        refactoring / modernization works for ASoC core and drivers, but there
        are lots of other changes as well. Here we go, some highlights below:
         - Quite a lot of cleanup / refactoring of ASoC core and APIs; most of
           them are systematic, but also including cleanups and modernization
         - A bulk of updates for some ASoC platforms, Freescale, sunxi and
           Intel SST/SOF
         - Initial support for Sound Open Firmware on i.MX8
         - Removal of deprecated w90x900 and nuc900 drivers
         - New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
           7ULP and 8MQ, Meson G12A and NXP UDA1334
         - More validations of descriptor units for hardening against bugs
           reported by fuzzers
         - PCM device assignment workaround for a past call-order change
         - Scarlett Gen2 mixer interface, a few more more quirks
         - Support for audio component with AMD/ATI and Nvidia HDMI codecs
         - Clean up HD-audio core and remove indirect access ops for Intel SOF
         - DMIC detection at probe; it would make systems automatically
           falling back to SST/SOF driver on devices that need DMIC handling.
           Needs a new Kconfig to set, and beware that it's still new and a
           bit experimental
         - Lots of code refactoring and cleanups"

           homebrewn caching of the leftmost node.
         - Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a
           single function
         - Implement the separation of hrtimers to be forced to expire in hard
           interrupt context even when PREEMPT_RT is enabled and mark the
           affected timers accordingly.
         - Implement a mechanism for hrtimers and the timer wheel to protect
           RT against priority inversion and live lock issues when a (hr)timer
           which should be canceled is currently executing the callback.
           Instead of infinitely spinning, the task which tries to cancel the
           timer blocks on a per cpu base expiry lock which is held and
           released by the (hr)timer expiry code.
         - Enable the Hyper-V TSC page based sched_clock for Hyper-V guests

      Pull x86 apic updates from Thomas Gleixner:
       - Cleanup the apic IPI implementation by removing duplicated code and
         consolidating the functions into the APIC core.
       - Implement a safe variant of the IPI broadcast mode. Contrary to
         earlier attempts this uses the core tracking of which CPUs have been
         brought online at least once so that a broadcast does not end up in
         some dead end in BIOS/SMM code when the CPU is still waiting for
         init. Once all CPUs have been brought up once, IPI broadcasting is
         enabled. Before that regular one by one IPIs are issued.
       - Drop the paravirt CR8 related functions as they have no user anymore
       - Initialize the APIC TPR to block interrupt 16-31 as they are reserved
         for CPU exceptions and should never be raised by any well behaving
       - Emit a warning when vector space exhaustion breaks the admin set
         affinity of an interrupt.
       - Make sure to use the NMI fallback when shutdown via reboot vector IPI
         fails. The original code had conditions which prevent the code path
         to be reached.
       - Annotate various APIC config variables as RO after init.
      [ The ipi broadcase change came in earlier through the cpu hotplug
        branch, but I left the explanation in the commit message since it was

       - MAINTAINERS: Add Mark Rutland as perf submaintainer, Juri Lelli and
         Vincent Guittot as scheduler submaintainers. Add Dietmar Eggemann,
         Steven Rostedt, Ben Segall and Mel Gorman as scheduler reviewers.
         As perf and the scheduler is getting bigger and more complex,
         document the status quo of current responsibilities and interests,
         and spread the review pain^H^H^H^H fun via an increase in the Cc:
         linecount generated by scripts/get_maintainer.pl. :-)
       - Add another series of patches that brings the -rt (PREEMPT_RT) tree
         closer to mainline: split the monolithic CONFIG_PREEMPT dependencies
         into a new CONFIG_PREEMPTION category that will allow the eventual
         introduction of CONFIG_PREEMPT_RT. Still a few more hundred patches
         to go though.
       - Extend the CPU cgroup controller with uclamp.min and uclamp.max to
         allow the finer shaping of CPU bandwidth usage.
       - Micro-optimize energy-aware wake-ups from O(CPUS^2) to O(CPUS).
       - Improve the behavior of high CPU count, high thread count
         applications running under cpu.cfs_quota_us constraints.
       - Improve balancing with SCHED_IDLE (SCHED_BATCH) tasks present.
       - Improve CPU isolation housekeeping CPU allocation NUMA locality.
       - Fix deadline scheduler bandwidth calculations and logic when cpusets
         rebuilds the topology, or when it gets deadline-throttled while it's
         being offlined.
       - Convert the cpuset_mutex to percpu_rwsem, to allow it to be used from
         setscheduler() system calls without creating global serialization.
         Add new synchronization between cpuset topology-changing events and
         the deadline acceptance tests in setscheduler(), which were broken
       - Rework the active_mm state machine to be less confusing and more
       - Rework (simplify) the pick_next_task() slowpath.
       - Improve load-balancing on AMD EPYC systems.
       - ... and misc cleanups, smaller fixes and improvements - please see
         the Git log for more details.

      Pull ARM DT updates from Arnd Bergmann:
       "This is another huge branch with close to 450 changessets related to
        devicetree files, roughly half of this for 32-bit and 64-bit
        respectively. There are lots of cleanups and additional hardware
        support for platforms we already support based on SoCs from Renesas,
        ST-Microelectronics, Intel/Altera, Rockchips, Allwinner, Broadcom and
        other manufacturers.
        A total of 6 new SoCs and 37 new boards gets added this time, one more
        SoC will come in a follow-up branch. Most of the new boards are for
        64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
        Going more into details for SoC platforms with new hardware support:
         - The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone
           platform, usually paired with an external 5G modem. So far we only
           support the Qualcomm SM8150 MTP reference platform, but no actual
         - For the slightly older Qualcomm platforms, support for several
           interesting products is getting added: Three laptops based on
           Snapdragon 835/MSM8998 (Asus NovaGo, HP Envy X2 and Lenovo Miix
           630), one laptop based on Snapdragon 850/sdm850 (Lenovo Yoga C630)
           and several phones based on the older Snapdragon 410/MSM8916
           (Samsung A3 and A5, Longcheer L8150 aka Android One 2nd gen "seed"
           aka Wileyfox Swift).
         - Mediatek MT7629 is a new wireless network router chip, similar to
           the older MT7623. It gets added together with the reference board
         - Allwinner V3 is a repackaged version of the existing low-end V3s
           chip, and is used in the tiny Lichee Pi Zero plus, also added here.
           There is also a new TV set-top box based on Allwinner H6, the Tanix
           TX6, and the eMMC variant of the Olimex A64-Olinuxino development
         - NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC
           family, similar to the i.MX8M Mini. As usual, there is a large
           number of new boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML,
           SolidRun Hummingboard Pulse baseboard and System-on-Module,
           Boundary Devices i.MX8MQ Nitrogen8M, and TechNexion
           PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit, we get the
           Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
           phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
           Innovations i.MX7 RMU2 board.
         - In a different NXP product line, the Layerscape LS1046A "Freeway"
           reference board gets added.
         - Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from
           their set-top-box line and smart speaker with newer CPU and GPU
           cores compared to their predecessors. Both are now also supported
           by the Khadas VIM3 development board series, and the dts files for
           that get reorganized a bit to better deal with all variants.
           Another board based on SM1 that gets added is the SEI Robotics
         - There are a handful of new x86 and Power9 server boards using
           Aspeed BMC chips that are gaining support for running Linux on the
           BMC through the OpenBMC project: Facebook
           Minipack/Wedge100/Wedge40, Lenovo Hr855xg2, and Mihawk. Notably
           these are still new machines using SoCs based on the ARM9 and ARM11
           CPU cores, as support for the new Cortex-A7 based AST2600 is still
           ramping up.
         - There are three new end-user products using 32-bit Rockchips SoCs:
           Mecer Xtreme Mini S6 is an Android "mini PC" box based on the
           low-end RK3229 chip, while the two AOpen products Chromebox Mini
           (Fievel) and Chromebase Mini (Tiger) run ChromeOS and are meant for
           commercial settings(digital signage, PoS, ...).
         - One more single-board computer based on the popular 64-bit RK3399
           is added: the Leez RK3399 P710"
