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 HID subsystem updates from Jiri Kosina:

 - The need for HID_QUIRK_NO_INIT_REPORTS per-device quirk has been
   growing dramatically during past years, so the time has come to
   switch over the default, and perform the pro-active reading only in
   cases where it's really needed (multitouch, wacom).

   The only place where this behavior is (in some form) preserved is
   hiddev so that we don't introduce userspace-visible change of
   behavior.

 - HID++ support for power_supply / baterry reporting.

   From Benjamin Tissoires and Bastien Nocera

68fed41e0f This is the bulk of pin control changes for the v4.12 cycle: 
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.

Merge tag 'pinctrl-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

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

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

   - input schmitt trigger support on the Rockchip driver.

   - name the Qualcomm QDF2xxx GPIO lines.

   - support GMMR GPIO regions on the Intel Cherryview. This fixes a

c58d4055c0 A reasonably busy cycle for documentation this time around. There is a new 
guide for user-space API documents, rather sparsely populated at the
 moment, but it's a start.  Markus improved the infrastructure for
 converting diagrams.  Mauro has converted much of the USB documentation
 over to RST.  Plus the usual set of fixes, improvements, and tweaks.
 
 There's a bit more than the usual amount of reaching out of Documentation/
 to fix comments elsewhere in the tree; I have acks for those where I could
 get them.

Merge tag 'docs-4.12' of git://git.lwn.net/linux

Pull documentation update from Jonathan Corbet:
 "A reasonably busy cycle for documentation this time around. There is a
  new guide for user-space API documents, rather sparsely populated at
  the moment, but it's a start. Markus improved the infrastructure for
  converting diagrams. Mauro has converted much of the USB documentation
  over to RST. Plus the usual set of fixes, improvements, and tweaks.

  There's a bit more than the usual amount of reaching out of
  Documentation/ to fix comments elsewhere in the tree; I have acks for
  those where I could get them"

2dbf3d5c32 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/egtvedt/linux-avr32 
Pull AVR32 removal from Hans-Christian Noren Egtvedt:
 "This will remove support for AVR32 architecture from the kernel and
  clean away the most obvious architecture related parts. Removing dead
  code in drivers is the next step"

Notes from previous discussion about this:
 "The AVR32 architecture is not keeping up with the development of the
  kernel, and since it shares so much of the drivers with Atmel ARM SoC,
  it is starting to hinder these drivers to develop swiftly.

  Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now
  Microchip).

  Finally, the GCC toolchain is stuck at version 4.2.x, and has not
  received any patches since the last release from Atmel;
  4.2.4-atmel.1.1.3.avr32linux.1.

  When building kernel v4.10, this toolchain is no longer able to
  properly link the network stack.

  Haavard and I have came to the conclusion that we feel keeping AVR32
  on life support offers more obstacles for Atmel ARMs, than it gives
  joy to AVR32 users. I also suspect there are very few AVR32 users left
  today, if anybody at all"

That discussion was acked by Andy Shevchenko, Boris Brezillon, Nicolas
Ferre, and Haavard Skinnemoen.

08be881064 ACPI updates for v4.12-rc1 
- Update the core device enumeration code to make it more internally
    consistent and robust and drop the force_remove sysfs attribute
    that could be used to tell it to ignore errors on device
    hot-removal which was dangerous in general and no real and
    still relevant use cases for it could be found (Rafael Wysocki,
    Michal Hocko).
 
  - Make the core device enumeration code use _PXM to associate
    platform devices created by it with specific NUMA nodes (Shanker
    Donthineni).
 
  - Extend the CPPC library by adding more sysfs entries for
    performance capabilities to it and making it use the lowest
    nonlinear performance parameter (Prashanth Prakash).
 
  - Make the CPU online more consistent with CPU initialization in
    the ACPI processor driver (Prashanth Prakash).
 
  - Update the AC and battery drivers to help them avoid attaching to
    devices that cannot be handled by them and update the axp288_charger
    power supply driver to work correctly on ACPI systems without the
    INT3496 device (Hans de Goede).
 
  - Add an ACPI operation region driver for the Intel CHT Whiskey Cove
    PMIC and update the xpower operation region driver to work without
    IIO which isn't really necessary for it to work (Hans de Goede).
 
  - Add a new entry for Dell Inspiron 7537 to the _REV quirk blacklist
    (Kai Heng Feng).
 
  - Make the code in the ACPI video driver easier to follow by adding
    symbols and comments to it (Dmitry Frank).
 
  - Update ACPI documentation and drop a function that has no users
    from the tables-handling code (Cao jin, Baoquan He).

Pull power management updates from Rafael Wysocki:
 "This time the majority of changes go to the cpufreq subsystem (and to
  the intel_pstate driver in particular) and there are some updates in
  the generic power domains framework, cpuidle, tools and a couple of
  other places.

  One thing worth mentioning is that the intel_pstate's sysfs interface
  has been reworked to be more consistent with the general expectations
  of the cpufreq core and less confusing, hopefully for the better.
  Also, we have a new cpufreq driver for Tegra186 and new hardware
  support in intel_pstata and the Mediatek cpufreq driver.

  Apart from that, the AnalyzeSuspend utility for system suspend
  profiling gets a companion called AnalyzeBoot for the analogous
  profiling of system boot and they both go into one place under
  tools/power/pm-graph/.

  The rest is mostly fixes, cleanups and code reorganization.

  Specifics:

   - Rework the intel_pstate driver's sysfs interface to make it more
     straightforward and more intuitive (Rafael Wysocki).

   - Make intel_pstate support all processors which advertise HWP

694752922b Merge branch 'for-4.12/block' of git://git.kernel.dk/linux-block 
Pull block layer updates from Jens Axboe:

 - Add BFQ IO scheduler under the new blk-mq scheduling framework. BFQ
   was initially a fork of CFQ, but subsequently changed to implement
   fairness based on B-WF2Q+, a modified variant of WF2Q. BFQ is meant
   to be used on desktop type single drives, providing good fairness.
   From Paolo.

 - Add Kyber IO scheduler. This is a full multiqueue aware scheduler,
   using a scalable token based algorithm that throttles IO based on
   live completion IO stats, similary to blk-wbt. From Omar.

 - A series from Jan, moving users to separately allocated backing
   devices. This continues the work of separating backing device life
   times, solving various problems with hot removal.

 - A series of updates for lightnvm, mostly from Javier. Includes a
   'pblk' target that exposes an open channel SSD as a physical block
   device.

 - A series of fixes and improvements for nbd from Josef.

 - A series from Omar, removing queue sharing between devices on mostly
   legacy drivers. This helps us clean up other bits, if we know that a
   queue only has a single device backing. This has been overdue for
   more than a decade.

 - Fixes for the blk-stats, and improvements to unify the stats and user
   windows. This both improves blk-wbt, and enables other users to
   register a need to receive IO stats for a device. From Omar.

 - blk-throttle improvements from Shaohua. This provides a scalable
   framework for implementing scalable priotization - particularly for
   blk-mq, but applicable to any type of block device. The interface is
   marked experimental for now.

 - Bucketized IO stats for IO polling from Stephen Bates. This improves
   efficiency of polled workloads in the presence of mixed block size
   IO.

 - A few fixes for opal, from Scott.

 - A few pulls for NVMe, including a lot of fixes for NVMe-over-fabrics.
   From a variety of folks, mostly Sagi and James Smart.

 - A series from Bart, improving our exposed info and capabilities from
   the blk-mq debugfs support.

 - A series from Christoph, cleaning up how handle WRITE_ZEROES.

 - A series from Christoph, cleaning up the block layer handling of how
   we track errors in a request. On top of being a nice cleanup, it also
   shrinks the size of struct request a bit.

 - Removal of mg_disk and hd (sorry Linus) by Christoph. The former was
   never used by platforms, and the latter has outlived it's usefulness.

 - Various little bug fixes and cleanups from a wide variety of folks.

* 'for-4.12/block' of git://git.kernel.dk/linux-block: (329 commits)
  block: hide badblocks attribute by default
  blk-mq: unify hctx delay_work and run_work

we have one reset line per PHY present on the MDIO bus, these
automatically become properties of the child PHY nodes.

Finally, indicate how the RESET pulse width must be defined, which is
the maximum value of all individual PHYs RESET pulse widths determined
by reading their datasheets.
