 "Notable changes:

   - Mitigations for Spectre v2 on some Freescale (NXP) CPUs.

   - A large series adding support for pass-through of Nvidia V100 GPUs
     to guests on Power9.

   - Another large series to enable hardware assistance for TLB table
     walk on MPC8xx CPUs.

   - Some preparatory changes to our DMA code, to make way for further
     cleanups from Christoph.

   - Several fixes for our Transactional Memory handling discovered by
     fuzzing the signal return path.

   - Support for generating our system call table(s) from a text file
     like other architectures.

   - A fix to our page fault handler so that instead of generating a
     WARN_ON_ONCE, user accesses of kernel addresses instead print a
     ratelimited and appropriately scary warning.

   - A cosmetic change to make our unhandled page fault messages more
     similar to other arches and also more compact and informative.

   - Freescale updates from Scott:
       "Highlights include elimination of legacy clock bindings use from
        dts files, an 83xx watchdog handler, fixes to old dts interrupt

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"

  x86, s390 and arm.

  I offered to take those conversions through the asm-generic tree that

  all but one have now been accepted into arch maintainer trees, so this
  branch only contains the conversion for arch/sh/, with permission from

  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

   - 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

   - Better spreading to NUMA nodes in the affinity management

   - 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.

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.

  improvments. One thing standing out is ground preparation for
  inititializing trigger parameters via Device Tree.

  We introduce LED_INIT_DEFAULT_TRIGGER flag for that purpose and set it
  when default trigger is matched. It indicates that trigger should
  parse DT properties to retrieve the initialization data when set as
  default one"

Pull regmap updates from Mark Brown:
 "This has been a busy release for the regmap-irq code, there's several
  new features been added, including an API cleanup for how we specify
  types that affected one existing driver (gpio-max77620):

   - Support for hardware that flags rising and falling edges on
     separate status bits from Bartosz Golaszewski.

   - Support for explicitly clearing interrupts before unmasking from
     Bartosz Golaszewski.

   - Support for level triggered IRQs from Matti Vaittinen"
