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"

 "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

  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

   - 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

  Core updates:

   - Better spreading to NUMA nodes in the affinity management

   - Support for more than one set of interrupts to spread out to allow

   - 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.

   - Make devm_of_clk_add_hw_provider() use parent dt node if necessary

Pull LED updates from Jacek Anaszewski:
 "There are several few-liners, where most of them are fixes and
  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 spi updates from Mark Brown:
 "The main thing this release has been a lot of work on the integration
  with SPI NOR flashes, there's been some specific support for a while
  for controller features designed to make them perform better but it's
  not worked out as well as hoped so the interface has been redesigned
  in a way that will hopefully do better - it's already been adopted by
  a number of additional controllers so things are looking good.

  Otherwise most of the work has been driver specific:

   - Support for better integration with NOR flashes from Boris
     Brezillon and Yogesh Narayan Gaur plus usage of it in several
     drivers.

   - A big cleanup of the Rockchip driver from Emil Renner Berthing.

  high-res timers for device autosuspend, fix a problem with
  suspend-to-idle on ACPI-based platforms, add system-wide suspend and

  all over and update some utilities.

  Specifics:

   - Add sysadmin documentation for cpuidle (Rafael Wysocki).

   - Make it possible to specify a cpuidle governor from kernel command
     line, add new cpuidle state sysfs attributes for governor
     evaluation, and improve the "polling" idle state handling (Rafael

     (Vincent Guittot).

   - Disable non-wakeup ACPI GPEs during suspend-to-idle so that they
     don't prevent the system from reaching the target low-power state
     and simplify the suspend-to-idle handling on ACPI platforms without
     full Low-Power S0 Idle (LPS0) support (Rafael Wysocki).

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

i.MX PWM module's ipg_clk_s is for PWM register access, on most of i.MX
SoCs, this ipg_clk_s is from system ipg clock or perclk which is always
enabled, but on i.MX7D, the ipg_clk_s is from PWM1_CLK_ROOT which is
controlled by CCGR132, that means the CCGR132 MUST be enabled first
before accessing PWM registers on i.MX7D. This patch adds ipg clock
operation to make sure register access successfully on i.MX7D and it
fixes Linux kernel boot up hang during PWM driver probe.

Commit e39c0df1 ("pwm: Introduce the pwm_args concept") has
changed the variable for the period for clps711x-pwm driver, so now
pwm_get/set_period() works with pwm->state.period variable instead
of pwm->args.period.
This patch changes the period variable in other places where it is used.

 "This is two simple target fixes and one discard related I/O starvation
  problem in sd.

  The discard problem occurs because the discard page doesn't have a

  then lose the forward progress we require if the writeout is on the
  same device. The fix is to back it with a mempool"
