550116d21a scripts/spelling.txt: add "aligment" pattern and fix typo instances
Fix typos and add the following to the scripts/spelling.txt:

  aligment||alignment

I did not touch the "N_BYTE_ALIGMENT" macro in
drivers/net/wireless/realtek/rtlwifi/wifi.h to avoid unpredictable
impact.

I fixed "_aligment_handler" in arch/openrisc/kernel/entry.S because
it is surrounded by #if 0 ... #endif.  It is surely safe and I
confirmed "_alignment_handler" is correct.

I also fixed the "controler" I found in the same hunk in
arch/openrisc/kernel/head.S.

9332ef9dbd scripts/spelling.txt: add "an user" pattern and fix typo instances
Fix typos and add the following to the scripts/spelling.txt:

  an user||a user
  an userspace||a userspace

I also added "userspace" to the list since it is a common word in Linux.
I found some instances for "an userfaultfd", but I did not add it to the
list.  I felt it is endless to find words that start with "user" such as
"userland" etc., so must draw a line somewhere.

7d134b2ce6 kprobes: move kprobe declarations to asm-generic/kprobes.h
Often all is needed is these small helpers, instead of compiler.h or a
full kprobes.h.  This is important for asm helpers, in fact even some
asm/kprobes.h make use of these helpers...  instead just keep a generic
asm file with helpers useful for asm code with the least amount of
clutter as possible.

Likewise we need now to also address what to do about this file for both
when architectures have CONFIG_HAVE_KPROBES, and when they do not.  Then
for when architectures have CONFIG_HAVE_KPROBES but have disabled
CONFIG_KPROBES.

Right now most asm/kprobes.h do not have guards against CONFIG_KPROBES,
this means most architecture code cannot include asm/kprobes.h safely.
Correct this and add guards for architectures missing them.
Additionally provide architectures that not have kprobes support with
the default asm-generic solution.  This lets us force asm/kprobes.h on
the header include/linux/kprobes.h always, but most importantly we can
now safely include just asm/kprobes.h on architecture code without
bringing the full kitchen sink of header files.

Two architectures already provided a guard against CONFIG_KPROBES on its
kprobes.h: sh, arch.  The rest of the architectures needed gaurds added.
We avoid including any not-needed headers on asm/kprobes.h unless
kprobes have been enabled.

In a subsequent atomic change we can try now to remove compiler.h from
include/linux/kprobes.h.

During this sweep I've also identified a few architectures defining a
common macro needed for both kprobes and ftrace, that of the definition
of the breakput instruction up.  Some refer to this as
BREAKPOINT_INSTRUCTION.  This must be kept outside of the #ifdef
CONFIG_KPROBES guard.

 needed for the thinkpad_acpi changes noted below
 
 This is the first time a pdx86 pull request has included a merge of an immutable
 branch from another subsystem, as we have previously either waited for the
 dependency to be merged, or asked the other maintainer to merge dependent
 changes. As this included three patches specifically to thinkpad_acpi, we
 decided to try the merge and apply model.

  - add another KEY_WLAN keycode
  - Inform firmware that RF Button Driver is active
  - setup accelerometer when machine has appropriate notify event
 
 asus-wireless:
  - Fix indentation
  - Use per-HID HSWC parameters

  - read s0ix residency API
  - Remove unused iTCO_version variable
 
 alienware-wmi:
  - Remove header duplicate
 
 intel_pmc_core:

ac1820fb28 This is a tree wide change and has been kept separate for that reason.
Bart Van Assche noted that the ib DMA mapping code was significantly
 similar enough to the core DMA mapping code that with a few changes
 it was possible to remove the IB DMA mapping code entirely and
 switch the RDMA stack to use the core DMA mapping code.  This resulted
 in a nice set of cleanups, but touched the entire tree.  This branch
 will be submitted separately to Linus at the end of the merge window
 as per normal practice for tree wide changes like this.

  was possible to remove the IB DMA mapping code entirely and switch the
  RDMA stack to use the core DMA mapping code.

  This resulted in a nice set of cleanups, but touched the entire tree
  and has been kept separate for that reason."

76062b4ae2 platform/x86: intel_pmc_ipc: read s0ix residency API
This patch adds a new API to indicate S0ix residency in usec. It utilizes
the PMC Global Control Registers (GCR) to read deep and shallow
S0ix residency.

PMC MMIO resources:
        o Lower 4kB: IPC1 (PMC inter-processor communication) interface
        o Upper 4kB: GCR (Global Control Registers)

This enables the power management framework to take corrective actions when
the platform fails to enter S0ix after kernel freeze as part of the suspend
to idle flow. (echo freeze > /sys/power/state).

This is expected to be used with a S0ix failsafe framework such as:

897ab3e0c4 userfaultfd: non-cooperative: add event for memory unmaps
When a non-cooperative userfaultfd monitor copies pages in the
background, it may encounter regions that were already unmapped.
Addition of UFFD_EVENT_UNMAP allows the uffd monitor to track precisely
changes in the virtual memory layout.

Since there might be different uffd contexts for the affected VMAs, we
first should create a temporary representation for the unmap event for
each uffd context and then notify them one by one to the appropriate
userfault file descriptors.

The event notification occurs after the mmap_sem has been released.

a00cc7d9dd mm, x86: add support for PUD-sized transparent hugepages
The current transparent hugepage code only supports PMDs.  This patch
adds support for transparent use of PUDs with DAX.  It does not include
support for anonymous pages.  x86 support code also added.

Most of this patch simply parallels the work that was done for huge
PMDs.  The only major difference is how the new ->pud_entry method in
mm_walk works.  The ->pmd_entry method replaces the ->pte_entry method,
whereas the ->pud_entry method works along with either ->pmd_entry or
->pte_entry.  The pagewalk code takes care of locking the PUD before
calling ->pud_walk, so handlers do not need to worry whether the PUD is
stable.

a4d4426635 openrisc: head: Init r0 to 0 on start
Originally openrisc spec 0 specified that r0 would be wired to ground.
This is no longer the case.  r0 is not guaranteed to be 0 at init, so we
need to initialize it to 0 before using it.

Also, if we are clearing r0 we cant use r0 to clear itself. Change the
the CLEAR_GPR macro to use movhi for clearing.

e6d20c55a4 openrisc: entry: Fix delay slot detection
Use execption SR stored in pt_regs for detection, the current SR is not
correct as the handler is running after return from exception.

Also, The code that checks for a delay slot uses a flag bitmask and then
wants to check if the result is not zero.  The test it implemented was
wrong.

Correct it by changing the test to check result against non zero.

f5d45dc911 openrisc: Add optimized memcpy routine
The generic memcpy routine provided in kernel does only byte copies.
Using word copies we can lower boot time and cycles spend in memcpy
quite significantly.

Booting on my de0 nano I see boot times go from 7.2 to 5.6 seconds.
The avg cycles in memcpy during boot go from 6467 to 1887.

I tested several algorithms (see code in previous patch mails)

The implementations I tested and avg cycles:
  - Word Copies + Loop Unrolls + Non Aligned    1882
  - Word Copies + Loop Unrolls                  1887
  - Word Copies                                 2441
  - Byte Copies + Loop Unrolls                  6467
  - Byte Copies                                 7600

In the end I ended up going with Word Copies + Loop Unrolls as it
provides best tradeoff between simplicity and boot speedups.

Merge tag 'drm-for-v4.11-less-shouty' of git://people.freedesktop.org/~airlied/linux

Pull drm updates from Dave Airlie:
 "This is the main drm pull request for v4.11.

  Nothing too major, the tinydrm and mmu-less support should make
  writing smaller drivers easier for some of the simpler platforms, and
  there are a bunch of documentation updates.

  Intel grew displayport MST audio support which is hopefully useful to
  people, and FBC is on by default for GEN9+ (so people know where to
  look for regressions). AMDGPU has a lot of fixes that would like new
  firmware files installed for some GPUs.

  Other than that it's pretty scattered all over.

  I may have a follow up pull request as I know BenH has a bunch of AST
  rework and fixes and I'd like to get those in once they've been tested
  by AST, and I've got at least one pull request I'm just trying to get

Pull ARM 64-bit DT updates from Arnd Bergmann:
 "ARM64 DT updates are fairly small this time, only two new SoCs and a
  handful of new machines get added, all of them similar to other
  hardware we already support.

  New SoC:

   - HiSilicon Kirin960/Hi3660 and HiKey960 development board

   - NXP LS1012a with three reference boards:
        http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/qoriq-layerscape-arm-processors/qoriq-layerscape-1012a-low-power-communication-processor:LS1012A

  New development board:

   - Banana Pi M64, based on Allwinner A64:
        http://www.banana-pi.org/m64.html

   - SolidRun MACCHIATOBin based on Marvell Armada 8K:
        https://www.solid-run.com/marvell-armada-family/armada-8040-community-board/

   - Broadcom BCM958712DxXMC NorthStar2 reference board (another one)

  A lot of platforms improve support for existing machines by adding
  extra devices for which a binding and driver is availabe:

  Allwinner:
   - MMC, USB

  ARM Juno:
   - Coresight, STM

  Broadcom:
   - NS2 GICv2m irqchip and PCIe

  Marvell:
   - Armada 3700 SPI, I2C, ethernet switch

  Mediatek:
   - MT8173 thermal

  NXP i.MX:
   - LS1046A thermal

  Qualcomm:
   - coresight on MSM8916, HDMI, WCNSS, SCM

  Renesas:
   - r8a779[56] thermal, powerdomain, ethernet, sound, pwm, can, can fd

  Rockchip:
   - thermal, eDP, pinctrl enhancements

  Samsung:
   - TM2 touchkey, Exynos5433 HDMI and power management improvements

  UniPhier:
