Pull ARM Device-tree updates from Olof Johansson:
 "Device-tree continues to see lots of updates. The majority of patches
  here are smaller changes for new hardware on existing platforms, and
  there are a few larger changes worth pointing out.

  Major new platforms:

   - Gemini has been ported to DT, so a handful of "new" platforms moved
     over from board files

   - Rockchip RK3288 support for Tinkerboard and Phytec phyCORE-RK3288
     SoM and RDK

   - A bunch of embedded platforms, several Linksys platforms, Synology
     DS116,

   - Motorola Droid4 (really old OMAP-based phone) support is added.

  Some refactorings, i.e. Allwinner H3/H5 support is commonalized.

  And lots of smaller changes, cleanups, etc. See shortlog for more
  description

  We're adding ability to cross-include DT files between arm and arm64,
  by creating appropriate links in the dt-include directory, and using
  arm/ and arm64/ as include prefixes. This will avoid other local hacks
  such as per-file links between the two arch trees (this broke for
  external mirroring of DT contents). Now they can just provide their
  own appropriate dt-include hierarcy per platform"

c718a97514 fs: semove set but not checked AOP_FLAG_UNINTERRUPTIBLE flag 
Commit afddba49d1 ("fs: introduce write_begin, write_end, and
perform_write aops") introduced AOP_FLAG_UNINTERRUPTIBLE flag which was
checked in pagecache_write_begin(), but that check was removed by
4e02ed4b4a ("fs: remove prepare_write/commit_write").

Between these two commits, commit d9414774dc ("cifs: Convert cifs to
new aops.") added a check in cifs_write_begin(), but that check was soon
removed by commit a98ee8c1c7 ("[CIFS] fix regression in
cifs_write_begin/cifs_write_end").

Therefore, AOP_FLAG_UNINTERRUPTIBLE flag is checked nowhere.  Let's
remove this flag.  This patch has no functionality changes.

37d69ee308 docs: bump minimal GNU Make version to 3.81 
Since 2014, you can't successfully build kernels with GNU Make version
3.80. Example errors:

  $ git describe
  v4.11
  $ make --version | head -1
  GNU Make 3.80
  $ make defconfig
    HOSTCC  scripts/basic/fixdep
  scripts/Makefile.host:135: *** missing separator.  Stop.
  make: *** [defconfig] Error 2
  $ make ARCH=arm64 help
  arch/arm64/Makefile:43: *** unterminated call to function `warning': missing `)'.  Stop.
  $ make help >/dev/null
  ./Documentation/Makefile.sphinx:25: Extraneous text after `else' directive
  ./Documentation/Makefile.sphinx:31: *** only one `else' per conditional.  Stop.
  make: *** [help] Error 2

The first breakage was introduced by commit c8589d1e9e ("kbuild:
handle multi-objs dependency appropriately").  Since then (i.e. v3.18),
GNU Make 3.80 has not been able to compile the kernel, but nobody has
ever complained aboutt (or noticed) it.

Even GNU Make 3.81 is more than 10 years old.  It would not hurt to
match the documentation with reality instead of fixing makefiles.

 "Here is the big staging tree update for 4.12-rc1.

  It's a big one, adding about 350k new lines of crap^Wcode, mostly all

  drivers in here as well, yet-another-wifi driver, new IIO drivers, and
  a new crypto accelerator.

  We also deleted a bunch of stuff, mostly in patch cleanups, but also
  the Android ION code has shrunk a lot, and the Android low memory
  killer driver was finally deleted, much to the celebration of the -mm
  developers.

  All of these have been in linux-next with a few build issues that will

   - Support for CAPI cards on Power9, using the "Coherent Accelerator
     Interface Architecture 2.0".

   - The ability to configure the mmap randomisation limits at build and
     runtime.

   - Several small fixes and cleanups to the kprobes code, as well as
     support for KPROBES_ON_FTRACE.

   - Major improvements to handling of system reset interrupts,
     correctly treating them as NMIs, giving them a dedicated stack and
     using a new hypervisor call to trigger them, all of which should
     aid debugging and robustness.

   - Many fixes and other minor enhancements.

drm/tegra: Changes for v4.12-rc1

This contains various fixes to the host1x driver as well as a plug for a
leak of kernel pointers to userspace.

A fairly big addition this time around is the Video Image Composer (VIC)
support that can be used to accelerate some 2D and image compositing
operations.

Furthermore the driver now supports FB modifiers, so we no longer rely
on a custom IOCTL to set those.

Finally this contains a few preparatory patches for Tegra186 support
which unfortunately didn't quite make it this time, but will hopefully
be ready for v4.13.

  wasn't an easy path for them at all.

  There's also a staging driver that uses this new api, which is why
  it's coming in through this tree.

  Along with that, there's the usual huge number of changes for gadget
  drivers, xhci, and other stuff. Johan also finally refactored pretty
  much every driver that was looking at USB endpoints to do it in a
  common way, which will help prevent any "badly-formed" devices from
  causing problems in drivers. That too wasn't a simple task.

2bd8040174 Merge tag 'gpio-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio 
Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.12 kernel cycle.

  Core changes:

   - Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
     This was a much discussed change. It affects use cases where people
     write drivers that might or might not be using GPIO resources. I
     have decided that this is the lesser evil right now.

   - Make gpiod_count() behave consistently across different hardware
     descriptions.

   - Fix the syntax around open drain/open source to not infer active
     high/low semantics.

  New drivers:

   - A new single-register fixed-direction framework driver for hardware
     that have lines controlled by a single register that just work in
     one direction (out or in), including IRQ support.

   - Support the Fintek F71889A GPIO SuperIO controller.

   - Support the National NI 169445 MMIO GPIO.

   - Support for the X-Gene derivative of the DWC GPIO controller

   - Support for the Rohm BD9571MWV-M PMIC GPIO controller.

   - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
     and replace both the Gemini and the Moxa ART custom drivers with
     this driver.

  Driver improvements:

   - A whole slew of drivers have their spinlocks chaned to raw
     spinlocks as they provide irqchips, and thus we are progressing on
     realtime compliance.

   - Use devm_irq_alloc_descs() in a slew of drivers, getting managed
     resources.

   - Support for the embedded PWM controller inside the MVEBU driver.

   - Debounce, open source and open drain support for the Aspeed driver.

   - Misc smaller fixes like spelling and syntax and whatnot"

Pull tracing updates from Steven Rostedt:
 "New features for this release:

   - Pretty much a full rewrite of the processing of function plugins.
     i.e. echo do_IRQ:stacktrace > set_ftrace_filter

   - The rewrite was needed to add plugins to be unique to tracing
     instances. i.e. mkdir instance/foo; cd instances/foo; echo
     do_IRQ:stacktrace > set_ftrace_filter The old way was written very
     hacky. This removes a lot of those hacks.

   - New "function-fork" tracing option. When set, pids in the
     set_ftrace_pid will have their children added when the processes
     with their pids listed in the set_ftrace_pid file forks.

   - Exposure of "maxactive" for kretprobe in kprobe_events

   - Allow for builtin init functions to be traced by the function
     tracer (via the kernel command line). Module init function tracing
     will come in the next release.

   - Added more selftests, and have selftests also test in an instance"

1684096b1e Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma 
Pull rdma updates from Doug Ledford:
 "More exchaustive description of primary updates in this release:

   - Lots of driver fixes and misc fixes across the board.

   - I had to base on a net-next tree because the IPoIB Accelorator
     patches needed it.

     Unfortunately, it was known to Mellanox that there would need to be
     an IPoIB accelorator patch to the net tree (which left some
     functions turned off by an #ifdef construct to avoid warnings about
     defined but unused functions), then one to the RDMA tree, then a
     fixup that went back and re-enabled the functions in the net tree
     and enabled their use in the rdma tree

     Also, a sparse fix was sent to the net tree after I did my pull,
     and the fixup patch conflicts quite directly with that sparse fix,
     so I'm going to submit the fixup patch towards the end of the merge
     window by itself and based upon your master branch at the time.

   - Two separate rounds of hfi1 fixes, one that got dropped from last
     release because it came in just a day or two before the end of the
     merge window and then the one from this release cycle.

     Of note is that I now have a third series that just landed from
     Intel yesterday. It is not included in this pull request, but I may
     submit it by the end of the week. I'll talk to Intel about
     improving the timing of thier submissions for my workflow.

   - Changes to our idr usage in the RDMA subsystem that will tie into
     our cgroup management and also into the upcoming changes for the
     RDMA kernel<->userspace API.

   - Addition of support for a netdev to be tied to an RDMA device at
     the core level

   - Addition of the VNIC driver from Intel.

     While IPoIB provides IP over InfiniBand (and *only* IP, no lower
     layer protocol headers are allowed or supported), the VNIC driver
     presents a virtual Ethernet device with support for things like
     varying Ethertypes, VLANs, priorities and other features of
     Ethernet.

     The virtual devices are centrally managed by the OPA fabric
     manager, making this (for the time being) a strictly OPA specific
     feature.

   - Improvements to the On-Demand Paging support in the RDMA subsystem.

   - Addition of three significant OPA changes.

     While we added OPA support some time ago (via the hfi1 driver), the
     RDMA subsystem has so far glossed over the areas where OPA and
     InfiniBand differ.

     With this release we are starting to add support for the OPA
     extensions into the RDMA core in the following area: Extended port
     information for OPA is now supported, extended Address Handle
     attributes for OPA are now supported, and extended SA Queries to
     get OPA specific subnet information is now supported.

  Concise summary from the tag:
   - idr usage and locking changes
   - build fix for hns
   - ipoib debug path record file fix
   - hfi1 updates
   - core RDMA netdev addition
   - Intel VNIC driver addition
   - Enhanced accelerators for IPoIB addition
   - Debug cleanups in cxgb3/4
   - Trivial cleanups from SF Markus Elfring
   - Misc rxe fixes from Mellanox
   - Misc ipoib fixes from Mellanox
   - Lots of mlx4/mlx5 changes from Mellanox
   - Misc fixes across the RDMA subsystem
   - ODP paging fixes and improvements
   - qedr updates
   - hfi1 updates
   - OPA port info patches
   - OPA AH patches
   - OPA SA Query patches"

d35a878ae1 Merge tag 'for-4.12/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm 
Pull device mapper updates from Mike Snitzer:

 - A major update for DM cache that reduces the latency for deciding
   whether blocks should migrate to/from the cache. The bio-prison-v2
   interface supports this improvement by enabling direct dispatch of
   work to workqueues rather than having to delay the actual work
   dispatch to the DM cache core. So the dm-cache policies are much more
   nimble by being able to drive IO as they see fit. One immediate
   benefit from the improved latency is a cache that should be much more
   adaptive to changing workloads.

 - Add a new DM integrity target that emulates a block device that has
   additional per-sector tags that can be used for storing integrity
   information.

 - Add a new authenticated encryption feature to the DM crypt target
   that builds on the capabilities provided by the DM integrity target.

 - Add MD interface for switching the raid4/5/6 journal mode and update
   the DM raid target to use it to enable aid4/5/6 journal write-back
   support.

 - Switch the DM verity target over to using the asynchronous hash
   crypto API (this helps work better with architectures that have
   access to off-CPU algorithm providers, which should reduce CPU
   utilization).

 - Various request-based DM and DM multipath fixes and improvements from
   Bart and Christoph.

 - A DM thinp target fix for a bio structure leak that occurs for each
   discard IFF discard passdown is enabled.

 - A fix for a possible deadlock in DM bufio and a fix to re-check the
   new buffer allocation watermark in the face of competing admin
   changes to the 'max_cache_size_bytes' tunable.

 - A couple DM core cleanups.

Pull livepatch updates from Jiri Kosina:

 - a per-task consistency model is being added for architectures that
   support reliable stack dumping (extending this, currently rather
   trivial set, is currently in the works).

   This extends the nature of the types of patches that can be applied
   by live patching infrastructure. The code stems from the design
   proposal made [1] back in November 2014. It's a hybrid of SUSE's
   kGraft and RH's kpatch, combining advantages of both: it uses
   kGraft's per-task consistency and syscall barrier switching combined
   with kpatch's stack trace switching. There are also a number of
   fallback options which make it quite flexible.

   Most of the heavy lifting done by Josh Poimboeuf with help from
   Miroslav Benes and Petr Mladek

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v4.12 cycle.

  The extra week before the merge window actually resulted in some of
  the type of fixes that usually arrive after the merge window already
  starting to trickle in from eager developers using -next, I'm
  impressed.

  I have recruited a Samsung subsubsystem maintainer (Krzysztof) to deal
  with the onset of Samsung patches. It works great.

  Apart from that it is a boring round, just incremental updates and
  fixes all over the place, no serious core changes or anything exciting
  like that. The most pleasing to see is Julia Cartwrights work to audit
  the irqchip-providing drivers for realtime locking compliance. It's
  one of those "I should really get around to looking into that" things
  that have been on my TODO list since forever.

  Summary:

  Core changes:

   - add bi-directional and output-enable pin configurations to the
     generic bindings and generic pin controlling core.

  New drivers or subdrivers:

   - Armada 37xx SoC pin controller and GPIO support.

   - Axis ARTPEC-6 SoC pin controller support.

   - AllWinner A64 R_PIO controller support, and opening up the
     AllWinner sunxi driver for ARM64 use.

   - Rockchip RK3328 support.

   - Renesas R-Car H3 ES2.0 support.

   - STM32F469 support in the STM32 driver.

   - Aspeed G4 and G5 pin controller support.

  Improvements:

   - a whole slew of realtime improvements to drivers implementing
     irqchips: BCM, AMD, SiRF, sunxi, rockchip.

   - switch meson driver to get the GPIO ranges from the device tree.

   - input schmitt trigger support on the Rockchip driver.

   - enable the sunxi (AllWinner) driver to also be used on ARM64
     silicon.

   - name the Qualcomm QDF2xxx GPIO lines.

   - support GMMR GPIO regions on the Intel Cherryview. This fixes a
     serialization problem on these platforms.

   - pad retention support for the Samsung Exynos 5433.

   - handle suspend-to-ram in the AT91-pio4 driver.

   - pin configuration support in the Aspeed driver.

  Cleanups:
