95f981f2e3 serial: doc: Always refer to tty_port->mutex
Stop referring to the mutex member of the tty_port struct as
'port->mutex', as 'port' is ambiguous, and usually refers to the
uart_port struct in this document.  Use 'tty_port->mutex' instead,
following the single existing use.

2bdbc5bc16 Documentation/memcg: update kmem limit doc as codes behavior
The restriction of kmem setting is not there anymore because the
accounting is enabled by default even in the cgroup v1 - see

cgroups in the legacy hierarchy").

934275c480 samples: v4l: from Documentation to samples directory
A small bug with the new autoksyms support showed that there are
two kernel modules in the Documentation directory that qualify
as samples, while all other samples are in the samples/ directory.

This patch was originally meant as a workaround for that bug, but
it has now been solved in a different way. However, I still think
it makes sense as a cleanup to consolidate all sample code in
one place.

Pull orangefs filesystem from Mike Marshall.

This finally merges the long-pending orangefs filesystem, which has been
much cleaned up with input from Al Viro over the last six months.  From
the documentation file:

 "OrangeFS is an LGPL userspace scale-out parallel storage system.  It
  is ideal for large storage problems faced by HPC, BigData, Streaming
  Video, Genomics, Bioinformatics.

  Orangefs, originally called PVFS, was first developed in 1993 by Walt
  Ligon and Eric Blumer as a parallel file system for Parallel Virtual
  Machine (PVM) as part of a NASA grant to study the I/O patterns of
  parallel programs.

  Orangefs features include:

    - Distributes file data among multiple file servers
    - Supports simultaneous access by multiple clients
    - Stores file data and metadata on servers using local file system
      and access methods
    - Userspace implementation is easy to install and maintain
    - Direct MPI support
    - Stateless"

see Documentation/filesystems/orangefs.txt for more in-depth details.

3d66c6ba3f Power management and ACPI material for v4.6-rc1, part 2
- Fix for an intel_pstate driver issue related to the handling of
    MSR updates uncovered by the recent cpufreq rework (Rafael Wysocki).
 
  - cpufreq core cleanups related to starting governors and frequency
    synchronization during resume from system suspend and a locking
    fix for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).
 
  - acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
    Michael Neuling, Richard Cochran, Shilpasri Bhat).
 
  - intel_idle driver update preventing some Skylake-H systems
    from hanging during initialization by disabling deep C-states
    mishandled by the platform in the problematic configurations (Len
    Brown).
 
  - Intel Xeon Phi Processor x200 support for intel_idle (Dasaratharaman
    Chandramouli).
 
  - cpuidle menu governor updates to make it always honor PM QoS
    latency constraints (and prevent C1 from being used as the
    fallback C-state on x86 when they are set below its exit latency)
    and to restore the previous behavior to fall back to C1 if the next
    timer event is set far enough in the future that was changed in 4.4
    which led to an energy consumption regression (Rik van Riel, Rafael
    Wysocki).
 
  - New device ID for a future AMD UART controller in the ACPI driver
    for AMD SoCs (Wang Hongcheng).
 
  - Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
    scaling (AVS) driver (David Wu).
 
  - ACPI PCI resources management fix for the handling of IO space
    resources on architectures where the IO space is memory mapped
    (IA64 and ARM64) broken by the introduction of common ACPI
    resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).

Pull more power management and ACPI updates from Rafael Wysocki:
 "The second batch of power management and ACPI updates for v4.6.

  Included are fixups on top of the previous PM/ACPI pull request and
  other material that didn't make into it but still should go into 4.6.

  Among other things, there's a fix for an intel_pstate driver issue
  uncovered by recent cpufreq changes, a workaround for a boot hang on
  Skylake-H related to the handling of deep C-states by the platform and
  a PCI/ACPI fix for the handling of IO port resources on non-x86
  architectures plus some new device IDs and similar.

  Specifics:

   - Fix for an intel_pstate driver issue related to the handling of MSR
     updates uncovered by the recent cpufreq rework (Rafael Wysocki).

   - cpufreq core cleanups related to starting governors and frequency
     synchronization during resume from system suspend and a locking fix
