      Pull RCU updates from Ingo Molnar:
       "The biggest RCU changes in this cycle were:
      
         - Convert RCU's BUG_ON() and similar calls to WARN_ON() and similar.
      
         - Replace calls of RCU-bh and RCU-sched update-side functions to
           their vanilla RCU counterparts. This series is a step towards
           complete removal of the RCU-bh and RCU-sched update-side functions.
      
           ( Note that some of these conversions are going upstream via their
             respective maintainers. )
      
         - Documentation updates, including a number of flavor-consolidation
           updates from Joel Fernandes.
      
         - Miscellaneous fixes.
      
         - Automate generation of the initrd filesystem used for rcutorture
           testing.
      
         - Convert spin_is_locked() assertions to instead use lockdep.
      
           ( Note that some of these conversions are going upstream via their
             respective maintainers. )
      
         - SRCU updates, especially including a fix from Dennis Krein for a
           bag-on-head-class bug.
      
         - RCU torture-test updates"

      Pull x86 microcode loading updates from Borislav Petkov:
       "This update contains work started by Maciej to make the microcode
        container verification more robust against all kinds of corruption and
        also unify verification paths between early and late loading.
      
        The result is a set of verification routines which validate the
        microcode blobs before loading it on the CPU. In addition, the code is
        a lot more streamlined and unified.
      
        In the process, some of the aspects of patch handling and loading were
        simplified.

      Linus Torvalds authored
      Pull x86 cache control updates from Borislav Petkov:
      
       - The generalization of the RDT code to accommodate the addition of
         AMD's very similar implementation of the cache monitoring feature.
      
         This entails a subsystem move into a separate and generic
         arch/x86/kernel/cpu/resctrl/ directory along with adding
         vendor-specific initialization and feature detection helpers.
      
         Ontop of that is the unification of user-visible strings, both in the
         resctrl filesystem error handling and Kconfig.
      
         Provided by Babu Moger and Sherry Hurwitz.

      Linus Torvalds authored
      Pull MIPS updates from Paul Burton:
       "Here's the main MIPS pull for Linux 4.21. Core architecture changes
        include:
      
         - Syscall tables & definitions for unistd.h are now generated by
           scripts, providing greater consistency with other architectures &
           making it easier to add new syscalls.
      
         - Support for building kernels with no floating point support, upon
           which any userland attempting to use floating point instructions
           will receive a SIGILL. Mostly useful to shrink the kernel & as
           preparation for nanoMIPS support which does not yet include FP.
      
         - MIPS SIMD Architecture (MSA) vector register context is now exposed
           by ptrace via a new NT_MIPS_MSA regset.
      
         - ASIDs are now stored as 64b values even for MIPS32 kernels,
           expanding the ASID version field sufficiently that we don't need to
           worry about overflow & avoiding rare issues with reused ASIDs that
           have been observed in the wild.
      
         - The branch delay slot "emulation" page is now mapped without write
           permission for the user, preventing its use as a nice location for
           attacks to execute malicious code from.
      
         - Support for ioremap_prot(), primarily to allow gdb or other ptrace
           users the ability to view their tracee's memory using the same
           cache coherency attribute.
      
         - Optimizations to more cpu_has_* macros, allowing more to be
           compile-time constant where possible.
      
         - Enable building the whole kernel with UBSAN instrumentation.
      
         - Enable building the kernel with link-time dead code & data
           elimination.
      
        Platform specific changes include:
      
         - The Boston board gains a workaround for DMA prefetching issues with
           the EG20T Platform Controller Hub that it uses.
      
         - Cleanups to Cavium Octeon code removing about 20k lines of
           redundant code, mostly unused or duplicate register definitions in
           headers.
      
         - defconfig updates for the DECstation machines, including new
           defconfigs for r4k & 64b machines.
      
         - Further work on Loongson 3 support.
      
         - DMA fixes for SiByte machines"

      Pull arch/sh syscall table scripting from Arnd Bergmann:
       "I worked with Firoz Khan to change all architectures to have their
        system call tables (syscall.S and asm/unistd.h) generated by a script
        from a more readable input file the same way that we already had on
        x86, s390 and arm.
      
        I offered to take those conversions through the asm-generic tree that
        did not get picked up by the architecture maintainers, and fortunately
        all but one have now been accepted into arch maintainer trees, so this
        branch only contains the conversion for arch/sh/, with permission from
        Rich.
      
        The conversion does not include the old 64-bit sh5 architecture, which
        has never shipped and not even compiled in a long time. The table in
        include/uapi/asm/unistd.h is also not included here, as Firoz is still
        working on that one, it will have to wait for the next following merge
        window, hopefully together with the addition of the 64-bit time_t
        system calls for the y2038 work that led to the system call table
        rework"

      Pull arm64 festive updates from Will Deacon:
       "In the end, we ended up with quite a lot more than I expected:
      
         - Support for ARMv8.3 Pointer Authentication in userspace (CRIU and
           kernel-side support to come later)
      
         - Support for per-thread stack canaries, pending an update to GCC
           that is currently undergoing review
      
         - Support for kexec_file_load(), which permits secure boot of a kexec
           payload but also happens to improve the performance of kexec
           dramatically because we can avoid the sucky purgatory code from
           userspace. Kdump will come later (requires updates to libfdt).
      
         - Optimisation of our dynamic CPU feature framework, so that all
           detected features are enabled via a single stop_machine()
           invocation
      
         - KPTI whitelisting of Cortex-A CPUs unaffected by Meltdown, so that
           they can benefit from global TLB entries when KASLR is not in use
      
         - 52-bit virtual addressing for userspace (kernel remains 48-bit)
      
         - Patch in LSE atomics for per-cpu atomic operations
      
         - Custom preempt.h implementation to avoid unconditional calls to
           preempt_schedule() from preempt_enable()
      
         - Support for the new 'SB' Speculation Barrier instruction
      
         - Vectorised implementation of XOR checksumming and CRC32
           optimisations
      
         - Workaround for Cortex-A76 erratum #1165522
      
         - Improved compatibility with Clang/LLD
      
         - Support for TX2 system PMUS for profiling the L3 cache and DMC
      
         - Reflect read-only permissions in the linear map by default
      
         - Ensure MMIO reads are ordered with subsequent calls to Xdelay()
      
         - Initial support for memory hotplug
      
         - Tweak the threshold when we invalidate the TLB by-ASID, so that
           mremap() performance is improved for ranges spanning multiple PMDs.

       "The interrupt department provides:
      
        Core updates:
      
         - Better spreading to NUMA nodes in the affinity management
      
         - Support for more than one set of interrupts to spread out to allow
           separate queues for separate functionality of a single device.
      
         - Decouple the non queue interrupts from being managed. Those are
           usually general interrupts for error handling etc. and those should
           never be shut down. This also a preparation to utilize the
           spreading mechanism for initial spreading of non-managed interrupts
           later.
      
         - Make the single CPU target selection in the matrix allocator more
           balanced so interrupts won't accumulate on single CPUs in certain
           situations.

      Pull clk updates from Stephen Boyd:
       "This round is dominated by NXP's i.MX clk drivers. We gained support
        for two or three i.MX SoCs in here and that mostly means a lot of
        driver code and data.
      
        Beyond that platform, there are some new Mediatek, Amlogic, and
        Qualcomm clk drivers added in here, and then we get to the long tail
        of driver updates and non-critical fixes all around, including code
        for vendors such as Renesas, Rockchip, Nvidia, and Allwinner. Overall,
        the driver updates look normal.
      
        Apart from the usual driver updates we have an update to make
        registering OF based clk providers a little simpler when they're
        devices created as a child of a device backed by a node in DT. Drivers
        don't have to jump through hoops to unregister the provider upon
        driver removal anymore because the API does the right thing and uses
        the parent device DT node.
      
        Summary:
      
        Core:
         - Make devm_of_clk_add_hw_provider() use parent dt node if necessary
         - Various SPDX taggings
         - Mark clk_ops const when possible

         - Allwinner H6 display engine clocks
         - Amlogic GX video clocks
         - Support for Amlogic meson8b CPU frequency scaling
         - Amlogic Meson8b CPU post-divider clocks

        a number of additional controllers so things are looking good.

      Pull sound updates from Takashi Iwai:
       "There are no intensive changes in both ALSA and ASoC core parts while
        rather most of changes are a bunch of driver fixes and updates. A
        large diff pattern appears in ASoC TI part which now merges both OMAP
        and DaVinci stuff, but the rest spreads allover the places.
      
        Note that this pull request includes also some updates for LED trigger
        and platform drivers for mute LEDs, appearing in the diffstat as well.
      
        Some highlights:
      
        ASoC:
         - Preparatory work for merging the audio-graph and audio-graph-scu
           cards
         - A merge of TI OMAP and DaVinci directories, as both product lines
           get merged together. Also including a few architecture changes as
           well.
         - Major cleanups of the Maxim MAX9867 driver
         - Small fixes for tablets & co with Intel BYT/CHT chips
         - Lots of rsnd updates as usual
         - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
           RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx
           I2S controllers
      
        HD-audio:
         - Introduce audio-mute LED trigger for replacing the former hackish
           dynamic binding
         - Huawei WMI hotkey and mute LED support
         - Refactoring of PM code and display power controls
         - Headset button support in the generic jack code
         - A few updates for Tegra
         - Fixups for HP EliteBook and ASUS UX391UA
         - Lots of updates for Intel ASoC HD-audio, including the improved DSP
           detection and the fallback binding from ASoC SST to legacy HD-audio
           controller drivers
      
        Others:
         - Updates for FireWire TASCAM and Fireface devices, some other fixes
         - A few potential Spectre v1 fixes that are all trivial"

      Pull x86 platform driver updates from Andy Shevchenko:
      
       - The USB Power Delivery discrete components now can be enumerated by
         i2c-multi-instantiate driver via several resources under single ACPI
         device node (ACPI ID is INT3515).
      
       - Touchscreen support is added for the Mediacom Flexbook Edge 11.
      
       - Mellanox driver got fixed due to updates in their firmware.
      
       - The power management stub driver for AtomISP v2 is fixed in order to
         support Intel Baytrail SoCs where same quirk is needed for S0ix to
         work.
      
       - Special key handling has been fixed for Favorites hotkey on Thinkpad,
         and Screen LOCK on ASUS.
      
       - Ideapad Yoga 2 13 has no HW rfkill switch, thus, driver has been
         updated to support this.
      
       - Few cleanups related to debugfs have been made in Intel IPS and Intel
         PMC drivers. Besides that Intel PMC has been extended to show more
         detailed information about Latency Tolerance
