We don't have any drivers left using it, so kill it off. Update
documentation to use the newer blk_queue_write_cache().

Add an internal helper and flag for setting whether a queue has
write back caching, or write through (or none). Add a sysfs file
to show this as well, and make it changeable from user space.
This will replace the (awkward) blk_queue_flush() interface that
drivers currently use to inform the block layer of write cache state
and capabilities.

Pull power management and ACPI fixes from Rafael Wysocki:
"Fixes for some issues discovered after recent changes and for some
that have just been found lately regardless of those changes
(intel_pstate, intel_idle, PM core, mailbox/pcc, turbostat) plus
support for some new CPU models (intel_idle, Intel RAPL driver,
turbostat) and documentation updates (intel_pstate, PM core).
Specifics:
- intel_pstate fixes for two issues exposed by the recent switch over
from using timers and for one issue introduced during the 4.4 cycle
plus new comments describing data structures used by the driver
(Rafael Wysocki, Srinivas Pandruvada).
- intel_idle fixes related to CPU offline/online (Richard Cochran).
- intel_idle support (new CPU IDs and state definitions mostly) for
Skylake-X and Kabylake processors (Len Brown).
- PCC mailbox driver fix for an out-of-bounds memory access that may
cause the kernel to panic() (Shanker Donthineni).
- New (missing) CPU ID for one apparently overlooked Haswell model in
the Intel RAPL power capping driver (Srinivas Pandruvada).
- Fix for the PM core's wakeup IRQs framework to make it work after
wakeup settings reconfiguration from sysfs (Grygorii Strashko).
- Runtime PM documentation update to make it describe what needs to
be done during device removal more precisely (Krzysztof Kozlowski).
- Stale comment removal cleanup in the cpufreq-dt driver (Viresh
Kumar).
- turbostat utility fixes and support for Broxton, Skylake-X and
Kabylake processors (Len Brown)"

Pull pin control fixes from Linus Walleij:
"Here is a set of pin control fixes for the v4.6 series.
A bit bigger than what I hoped for, but all fixes are confined to
drivers, a few of them also targeted to stable.
Summary:
- On Super-H PFC (Renesas) controllers: only use dummies on legacy
systems. This fixes a serious ethernet regression on a Renesas
board.
- Pistachio: Fix errors in the pin table.
- Allwinner SunXi: fix the external interrupts to work.
- Intel: fix so the high level interrupts start working, and fix a
spurious interrupt issue.
- Qualcomm ipq4019: fix the number of GPIOs provided (bump to 100),
correct register offsets and handle GPIO mode properly.
- Revert the revert on the revert so that Xway has a .to_irq()
callback again.
- Minor fixes to errorpaths and debug info.
- A MAINTAINERS update"

Merge PAGE_CACHE_SIZE removal patches from Kirill Shutemov:
"PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
ago with promise that one day it will be possible to implement page
cache with bigger chunks than PAGE_SIZE.
This promise never materialized. And unlikely will.
Let's stop pretending that pages in page cache are special. They are
not.
The first patch with most changes has been done with coccinelle. The
second is manual fixups on top.
The third patch removes macros definition"
[ I was planning to apply this just before rc2, but then I spaced out,
so here it is right _after_ rc2 instead.
As Kirill suggested as a possibility, I could have decided to only
merge the first two patches, and leave the old interfaces for
compatibility, but I'd rather get it all done and any out-of-tree
modules and patches can trivially do the converstion while still also
working with older kernels, so there is little reason to try to
maintain the redundant legacy model. - Linus ]
* PAGE_CACHE_SIZE-removal:
mm: drop PAGE_CACHE_* and page_cache_{get,release} definition
mm, fs: remove remaining PAGE_CACHE_* and page_cache_{get,release} usage
mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros

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.

Bunch of small fixupes all over. Plus a dma-buf patch that Sumit asked me
to cherry-pick since that's the only one he had in his tree.
There's a sparse issue outstanding in the color mgr stuff, but Lionel is
still working on something that actually appeases sparse.

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
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).
- Fix for the ACPI backend of the generic device properties API to
make it parse non-device (data node only) children of an ACPI
device correctly (Irina Tirdea).
- Fixes for the handling of global suspend flags (introduced in 4.4)
during hibernation and resume from it (Lukas Wunner).
- Support for obtaining configuration information from Device Trees
in the PM clocks framework (Jon Hunter).
- ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
King, Geert Uytterhoeven)"

This adds the necessary data for handling io voltage domains on the rk3399.
As interesting tidbit, the rk3399 contains two separate iodomain areas.
One in the regular General Register Files (GRF) and one in PMUGRF in the
pmu power domain.

As the SAMA5D2 controller supports the 32-bit ECC strength, accept it
as a valid setting when required by the device tree or the NAND
parameter page.
Then configure the controller to use this new setting.

Starting with the SAMA5D2, there is a new revision of the Atmel PMECC
controller that can correct 32 bits in each sector. This controller is
not 100% compatible with the previous revision that corrected a maximum
of 24 bits by sector, as some register addresses overlap.
Using information from the device tree, we can configure the driver to
work with both versions.

"Apologies for the previous request, which omitted the top 8 commits
from my for-next branch (including the SCSI layout commits). Thanks
to Trond for spotting my error!"
This actually includes the new layout types, so here's that part of
the pull message repeated:
"Support for a new pnfs layout type from Christoph Hellwig. The new
layout type is a variant of the block layout which uses SCSI features
to offer improved fencing and device identification.
Note this pull request also includes the client side of SCSI layout,
with Trond's permission"

This is a simple extension to the block layout driver to use SCSI
persistent reservations for access control and fencing, as well as
SCSI VPD pages for device identification.
For this we need to pass the nfs4_client to the proc_getdeviceinfo method
to generate the reservation key, and add a new fence_client method
to allow for fence actions in the layout driver.

- Uniphier renames a few files to match the final product names that
were decided by the company, kudos to the kernel developer(s) for
getting support upstream before the product release. Also two
boards are added. The patches were posted early enough and nice
overall, but we forgot to apply them and decided to give it some
more time in linux-next
