a3719f34fd Merge branch 'generic' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull quota, reiserfs, udf and ext2 updates from Jan Kara:
 "The branch contains changes to quota code so that it does not modify
  persistent flags in inode->i_flags (it was the only place in kernel
  doing that) and handle it inside filesystem's quotaon/off handlers
  instead.

  The branch also contains two UDF cleanups, a couple of reiserfs fixes
  and one fix for ext2 quota locking"

5133cd7518 Merge branch 'fsnotify' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull fsnotify updates from Jan Kara:
 "The branch contains mainly a rework of fsnotify infrastructure fixing
  a shortcoming that we have waited for response to fanotify permission
  events with SRCU read lock held and when the process consuming events
  was slow to respond the kernel has stalled.

  It also contains several cleanups of unnecessary indirections in
  fsnotify framework and a bugfix from Amir fixing leakage of kernel
  internal errno to userspace"

d35a878ae1 - 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.

 - Add Partial Parity Log (ppl) feature found in Intel IMSM raid array
   by Artur Paszkiewicz. This feature is another way to close RAID5
   writehole. The Linux implementation is also available for normal
   RAID5 array if specific superblock bit is set.

Pull audit updates from Paul Moore:
 "Fourteen audit patches for v4.12 that span the full range of fixes,
  new features, and internal cleanups.

  We have a patches to move to 64-bit timestamps, convert refcounts from
  atomic_t to refcount_t, track PIDs using the pid struct instead of
  pid_t, convert our own private audit buffer cache to a standard
  kmem_cache, log kernel module names when they are unloaded, and
  normalize the NETFILTER_PKT to make the userspace folks happier.

  From a fixes perspective, the most important is likely the auditd
  connection tracking RCU fix; it was a rather brain dead bug that I'll
  take the blame for, but thankfully it didn't seem to affect many
  people (only one report).

  I think the patch subject lines and commit descriptions do a pretty
  good job of explaining the details and why the changes are important
  so I'll point you there instead of duplicating it here; as usual, if
  you have any questions you know where to find us.

  We also manage to take out more code than we put in this time, that
  always makes me happy :)"

76f1948a79 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching
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

  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:

   - the final name of Rockchip RK1108 was RV1108 so rename the driver
     and variables to stay consistent"

  10) Remove TCP timewait recycling, it never really could possibly work
      well in the real world and timestamp randomization really zaps any
      hint of usability this feature had (Soheil Hassas Yeganeh)

  11) Support level3 vs level4 ECMP route hashing in ipv4 (Nikolay

8d3f87d8cd qed*: Fix issues in the ptp filter config implementation.
PTP hardware filter configuration performed by the driver for a given
user requested config is not correct for some of the PTP modes.
Following changes are needed for PTP config-filter implementation.
 1. NIG_REG_TX_PTP_EN register - Bits 0/1/2 respectively enables
    TimeSync/"V1 frame format support"/"V2 frame format support" on
    the TX side. Set the associated bits based on the user request.
 2. ptp4l application fails to operate in Peer Delay mode. Following
    changes are needed to fix this,
    a. Driver should enable (set to 0) DA #1-related bits for IPv4,
       IPv6 and MAC destination addresses in these registers:
         NIG_REG_TX_LLH_PTP_RULE_MASK
         NIG_REG_LLH_PTP_RULE_MASK
    b. NIG_REG_LLH_PTP_PARAM_MASK/NIG_REG_TX_LLH_PTP_PARAM_MASK should
       be set to 0x0 in all modes.

2115bb250f audit: Use timespec64 to represent audit timestamps
struct timespec is not y2038 safe.
Audit timestamps are recorded in string format into
an audit buffer for a given context.
These mark the entry timestamps for the syscalls.
Use y2038 safe struct timespec64 to represent the times.
The log strings can handle this transition as strings can
hold upto 1024 characters.

7ed8578a96 dm rq: change ->rq_end_io calling conventions
Instead of returning either a DM_ENDIO_* constant or an error code, add
a new DM_ENDIO_DONE value that means keep errno as is.  This allows us
to easily keep the existing error code in case where we can't push back,
and it also preparares for the new block level status codes with strict
type checking.

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

48e75b4306 rhashtable: compact struct rhashtable_params
By using smaller datatypes this (rather large) struct shrinks considerably
(80 -> 48 bytes on x86_64).

As this is embedded in other structs, this also rerduces size of several
others, e.g. cls_fl_head or nft_hash.

Merge tag 'leds_for_4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds

Pull LED updates from Jacek Anaszewski:
 "New drivers:

   - add LED support for MT6323 PMIC

   - add LED support for Motorola CPCAP PMIC

  New features and improvements:

   - add LED trigger for all CPUs aggregated which is useful on tiny
     boards with more CPU cores than LED pins

   - add OF variants of LED registering functions as a preparation for
     adding generic support for Device Tree parsing

   - dell-led improvements and cleanups, followed by moving it to the
     x86 platform driver subsystem which is a more appropriate place for
     it

   - extend pca9532 Device Tree support by adding the LEDs
     'default-state' property

   - extend pca963x Device Tree support by adding nxp,inverted-out
     property for inverting the polarity of the output

   - remove ACPI support for lp3952 since it relied on a non-official
     ACPI IDs"
