48ead50c1d Input: Add touchscreen support for Colibri VF50 
The Colibri Vybrid VF50 module supports 4-wire touchscreens using
FETs and ADC inputs. This driver uses the IIO consumer interface
and relies on the vf610_adc driver based on the IIO framework.

a9b85f9415 userfaultfd: change the read API to return a uffd_msg 
I had requests to return the full address (not the page aligned one) to
userland.

It's not entirely clear how the page offset could be relevant because
userfaults aren't like SIGBUS that can sigjump to a different place and it
actually skip resolving the fault depending on a page offset.  There's
currently no real way to skip the fault especially because after a
UFFDIO_COPY|ZEROPAGE, the fault is optimized to be retried within the
kernel without having to return to userland first (not even self modifying
code replacing the .text that touched the faulting address would prevent
the fault to be repeated).  Userland cannot skip repeating the fault even
more so if the fault was triggered by a KVM secondary page fault or any
get_user_pages or any copy-user inside some syscall which will return to
kernel code.  The second time FAULT_FLAG_RETRY_NOWAIT won't be set leading
to a SIGBUS being raised because the userfault can't wait if it cannot
release the mmap_map first (and FAULT_FLAG_RETRY_NOWAIT is required for
that).

Still returning userland a proper structure during the read() on the uffd,
can allow to use the current UFFD_API for the future non-cooperative
extensions too and it looks cleaner as well.  Once we get additional
fields there's no point to return the fault address page aligned anymore
to reuse the bits below PAGE_SHIFT.

The only downside is that the read() syscall will read 32bytes instead of
8bytes but that's not going to be measurable overhead.

The total number of new events that can be extended or of new future bits
for already shipped events, is limited to 64 by the features field of the
uffdio_api structure.  If more will be needed a bump of UFFD_API will be
required.

25edd8bffd userfaultfd: linux/Documentation/vm/userfaultfd.txt 
This is the latest userfaultfd patchset.  The postcopy live migration
feature on the qemu side is mostly ready to be merged and it entirely
depends on the userfaultfd syscall to be merged as well.  So it'd be great
if this patchset could be reviewed for merging in -mm.

Userfaults allow to implement on demand paging from userland and more
generally they allow userland to more efficiently take control of the
behavior of page faults than what was available before (PROT_NONE +
SIGSEGV trap).

The use cases are:

1) KVM postcopy live migration (one form of cloud memory
   externalization).

   KVM postcopy live migration is the primary driver of this work:

    http://blog.zhaw.ch/icclab/setting-up-post-copy-live-migration-in-openstack/
    http://lists.gnu.org/archive/html/qemu-devel/2015-02/msg04873.html

2) postcopy live migration of binaries inside linux containers:

    http://thread.gmane.org/gmane.linux.kernel.mm/132662

3) KVM postcopy live snapshotting (allowing to limit/throttle the
   memory usage, unlike fork would, plus the avoidance of fork
   overhead in the first place).

   While the wrprotect tracking is not implemented yet, the syscall API is
   already contemplating the wrprotect fault tracking and it's generic enough
   to allow its later implementation in a backwards compatible fashion.

4) KVM userfaults on shared memory. The UFFDIO_COPY lowlevel method
   should be extended to work also on tmpfs and then the
   uffdio_register.ioctls will notify userland that UFFDIO_COPY is
   available even when the registered virtual memory range is tmpfs
   backed.

5) alternate mechanism to notify web browsers or apps on embedded
   devices that volatile pages have been reclaimed. This basically
   avoids the need to run a syscall before the app can access with the
   CPU the virtual regions marked volatile. This depends on point 4)
   to be fulfilled first, as volatile pages happily apply to tmpfs.

Even though there wasn't a real use case requesting it yet, it also
allows to implement distributed shared memory in a way that readonly
shared mappings can exist simultaneously in different hosts and they
can be become exclusive at the first wrprotect fault.

This patch (of 22):

Add documentation.

abebcdfb64 sound updates for 4.3-rc1 
There are little changes in core part, but lots of development are
 found in drivers, especially ASoC.  The diffstat shows regmap-
 related changes for a slight API additions / changes, and that's all.
 
 Looking at the code size statistics, the most significant addition
 is for Intel Skylake.  (Note that SKL support is still underway, the
 codec driver is missing.)  Also STI controller driver is a major
 addition as well as a few new codec drivers.
 
 In HD-audio side, there are fewer changes than the past.  The
 noticeable change is the support of ELD notification from i915
 graphics driver.  Thus this pull request carries a few changes in
 drm/i915.
 
 Other than that, USB-audio got a rewrite of runtime PM code.  It
 was initiated by lockdep warning, but resulted in a good cleanup in
 the end.
 
 Below are the highlights:
 
 Common:
 - Factoring out of AC'97 reset code from ASoC into the core helper
 - A few regmap API extensions (in case it's not pulled yet)
 
 ASoC:
 - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
   RT298 and ST STI controllers
 - Machine drivers for Rockchip systems with MAX98090 and RT5645 and
   RT5650
 - Initial driver support for Intel Skylake devices
 - Lots of rsnd cleanup and enhancements
 - A few DAPM fixes and cleanups
 - A large number of cleanups in various drivers (conversion and
   standardized to regmap, component) mostly by Lars-Peter and Axel
 
 HD-audio:
 - Extended HD-audio core for Intel Skylake controller support
 - Quirks for Dell headsets, Alienware 15
 - Clean up of pin-based quirk tables for Realtek codecs
 - ELD notifier implenetation for Intel HDMI/DP
 
 USB-audio:
 - Refactor runtime PM code to make lockdep happier

[ The Kconfig and Makefile entries got re-sorted alphabetically, and I
  handled the conflict with the new Intel integrated IDMA driver by
  slightly mis-sorting it on purpose: "IDMA64" got sorted after "IMX" in
  order to keep the Intel entries together.  I think it might be a good
  idea to just rename the IDMA64 config entry to INTEL_IDMA64 to make
  the sorting be a true sort, not this mismash.

  Also, this merge disables the COMPILE_TEST for the sun4i DMA
  controller, because it does not compile cleanly at all.     - Linus ]

 - It is possible configure groups in debugfs.
 
 - Consolidation of chained IRQ handler install/remove replacing
   all call sites where irq_set_handler_data() and
   irq_set_chained_handler() were done in succession with a

8d2faea672 This is the bulk of GPIO changes for the v4.3 kernel cycle: 
Core changes:
 
 - Root out the wrapper devm_gpiod_get() and gpiod_get() etc
   versions of the descriptor calls that did not use the flags
   argument on the end. This was around for too long and eventually
   Uwe Kleine-König took the time to clean it out and the last
   users are removed along with the macros in this tag. In several
   cases the use of flags simplifies the code. For this reason we
   have (ACKed) patches hitting in DRM, IIO, media, NFC, USB+PHY
   up until we hammer in the nail with removing the macros.
 
 - Add a fat document describing how much ready-made GPIO stuff
   we have i the kernel to discourage people from reinventing
   a square wheel in userspace, as so often happens.
 
 - Create a separate lockdep class for each instance of a GPIO
   IRQ chip instead of using one class for all chips, as the current
   code will not work with systems with several GPIO chips doing
   lockdep debugging.
 
 - Protect against driver unloading also when a GPIO line is only
   used as IRQ for the GPIOLIB_IRQCHIP helpers.
 
 - If the GPIO chip has no designated owner, assign the parent
   device driver owner as owner.
 
 - Consolidation of chained IRQ handler install/remove replacing
   all call sites where irq_set_handler_data() and
   irq_set_chained_handler() were done in succession with a
   combined call to irq_set_chained_handler_and_data(). This
   series was created by Thomas Gleixner after the problem was
   observed by Russell King.
 
 - Tglx also made another series of patches switching
   __irq_set_handler_locked() for irq_set_handler_locked() which
   is way cleaner.
 
 - Tglx and Jiang Liu wrote a good bunch of patches to make use of
   irq_desc_get_xxx() accessors and avoid looking up irq_descs
   from IRQ numbers. The goal is to get rid of the irq number
   from the handlers in the IRQ flow which is nice.
 
 - Rob Herring killed off the set_irq_flags() for all GPIO
   drivers. This was an ARM specific function that is replaced
   with the generic irq_modify_status() where special flags
   are actually needed.
 
 - When an OF node has a pin range for its GPIOs, return
   -EPROBE_DEFER if the pin controller isn't available.
   Pretty logical, yet needed to be fixed.
 
 - If a driver using GPIOLIB_IRQCHIP has its own
   irq_*_resources call back, then call these instead of the
   defaults provided by the GPIOLIB.
 
 - Fix an undocumented ABI hole: named GPIOs were not
   properly documented.
 
 Driver improvements:
 
 - Add get_direction() support to the generic GPIO driver, it's
   strange that we didn't have that before.
 
 - Make it possible to have input-only GPIO chips using the
   generic GPIO driver.
 
 - Clean out platform data support from the Emma Mobile (EM)
   driver
 
 - Finegrained runtime PM support for the RCAR driver.
 
 - Support r8a7795 (R-car H3) in the RCAR driver.
 
 - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.
 
 - Some consolidation and new support in the MPC8xxx driver,
   we now support MPC5125.
 
 - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
   spinlocks making it work better with the realime patches.
 
 - Interrupt support for the EXTRAXFS GPIO driver.
 
 - Make the ETRAXFS GPIO driver support also ARTPEC-3.
 
 - Interrupt and wakeup support for the BRCMSTB driver, also for
   wakeup from S5 cold boot.
 
 - Mask MXC IRQs during suspend.
 
 - Improve OMAP2 GPIO set_debounce() to work according to spec.
 
 - The VF610 driver handles IRQs properly.
 
 New drivers:
 
 - ZTE ZX GPIO driver.

     __irq_set_handler_locked() for irq_set_handler_locked() which is
     way cleaner.

   - Tglx and Jiang Liu wrote a good bunch of patches to make use of
     irq_desc_get_xxx() accessors and avoid looking up irq_descs from
     IRQ numbers.  The goal is to get rid of the irq number from the
     handlers in the IRQ flow which is nice.

   - Rob Herring killed off the set_irq_flags() for all GPIO drivers.
     This was an ARM specific function that is replaced with the generic
     irq_modify_status() where special flags are actually needed.

   - When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER
     if the pin controller isn't available.  Pretty logical, yet needed
     to be fixed.

   - If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call
     back, then call these instead of the defaults provided by the
     GPIOLIB.

   - Fix an undocumented ABI hole: named GPIOs were not properly
     documented.

  Driver improvements:

   - Add get_direction() support to the generic GPIO driver, it's
     strange that we didn't have that before.

   - Make it possible to have input-only GPIO chips using the generic
     GPIO driver.

   - Clean out platform data support from the Emma Mobile (EM) driver

   - Finegrained runtime PM support for the RCAR driver.

   - Support r8a7795 (R-car H3) in the RCAR driver.

   - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.

   - Some consolidation and new support in the MPC8xxx driver, we now
     support MPC5125.

   - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
     spinlocks making it work better with the realime patches.

   - Interrupt support for the EXTRAXFS GPIO driver.

   - Make the ETRAXFS GPIO driver support also ARTPEC-3.

   - Interrupt and wakeup support for the BRCMSTB driver, also for
     wakeup from S5 cold boot.

   - Mask MXC IRQs during suspend.

   - Improve OMAP2 GPIO set_debounce() to work according to spec.

   - The VF610 driver handles IRQs properly.

  New drivers:

   - ZTE ZX GPIO driver"

Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for 4.3 for MIPS.  Here's the summary:

  Three fixes that didn't make 4.2-stable:

   - a -Os build might compile the kernel using the MIPS16 instruction
     set but the R2 optimized inline functions in <uapi/asm/swab.h> are
     implemented using 32-bit wide instructions which is invalid.

   - a build error in pgtable-bits.h for a particular kernel
     configuration.

   - accessing registers of the CM GCR might have been compiled to use
     64 bit accesses but these registers are onl 32 bit wide.

  And also a few new bits:

   - move the ATH79 GPIO driver to drivers/gpio

   - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
     change ATH79 accordingly.

   - fix definition of pgprot_writecombine

   - add an implementation of dma_map_ops.mmap

   - fix alignment of quiet build output for vmlinuz link

   - BCM47xx: Use kmemdup rather than duplicating its implementation

   - Netlogic: Fix 0x0x prefixes of constants.

   - merge Bjorn Helgaas' series to remove most of the weak keywords
     from function declarations.

   - CP0 and CP1 registers are best considered treated as unsigned
     values to avoid large values from becoming negative values.

   - improve support for the MIPS GIC timer.

   - enable common clock framework for Malta and SEAD3.

   - a number of improvments and fixes to dump_tlb().

   - document the MIPS TLB dump functionality in Magic SysRq.

   - Cavium Octeon CN68XX improvments.

   - NetLogic improvments.

   - irq: Use access helper irq_data_get_affinity_mask.

   - handle MSA unaligned accesses.

   - a number of R6-related math-emu fixes.

   - support for I6400.

   - improvments to MSA support.

   - add uprobes support.

   - move from deprecated __initcall to arch_initcall.

   - remove finish_arch_switch().

   - IRQ cleanups by Thomas Gleixner.

   - migrate to new 'set-state' interface.

   - random small cleanups"

Pull locking and atomic updates from Ingo Molnar:
 "Main changes in this cycle are:

   - Extend atomic primitives with coherent logic op primitives
     (atomic_{or,and,xor}()) and deprecate the old partial APIs
     (atomic_{set,clear}_mask())

     The old ops were incoherent with incompatible signatures across
     architectures and with incomplete support.  Now every architecture
     supports the primitives consistently (by Peter Zijlstra)

   - Generic support for 'relaxed atomics':

       - _acquire/release/relaxed() flavours of xchg(), cmpxchg() and {add,sub}_return()
       - atomic_read_acquire()
       - atomic_set_release()

     This came out of porting qwrlock code to arm64 (by Will Deacon)

   - Clean up the fragile static_key APIs that were causing repeat bugs,
     by introducing a new one:

       DEFINE_STATIC_KEY_TRUE(name);
       DEFINE_STATIC_KEY_FALSE(name);

     which define a key of different types with an initial true/false
     value.

     Then allow:

       static_branch_likely()
       static_branch_unlikely()

     to take a key of either type and emit the right instruction for the
     case.  To be able to know the 'type' of the static key we encode it
     in the jump entry (by Peter Zijlstra)

   - Static key self-tests (by Jason Baron)

   - qrwlock optimizations (by Waiman Long)

   - small futex enhancements (by Davidlohr Bueso)

Pull f2fs updates from Jaegeuk Kim:
 "The major work includes fixing and enhancing the existing extent_cache
  feature, which has been well settling down so far and now it becomes a
  default mount option accordingly.

  Also, this version newly registers a f2fs memory shrinker to reclaim
  several objects consumed by a couple of data structures in order to
  avoid memory pressures.

  Another new feature is to add ioctl(F2FS_GARBAGE_COLLECT) which
  triggers a cleaning job explicitly by users.

  Most of the other patches are to fix bugs occurred in the corner cases
  across the whole code area"

Pull ext3 removal, quota & udf fixes from Jan Kara:
 "The biggest change in the pull is the removal of ext3 filesystem
  driver (~28k lines removed).  Ext4 driver is a full featured
  replacement these days and both RH and SUSE use it for several years
  without issues.  Also there are some workarounds in VM & block layer
  mainly for ext3 which we could eventually get rid of.

  Other larger change is addition of proper error handling for
  dquot_initialize().  The rest is small fixes and cleanups"

[ I wasn't convinced about the ext3 removal and worried about things

  networking change of the year.  But what do I know?

   1) Add conntrack support to openvswitch, from Joe Stringer.

   2) Initial support for VRF (Virtual Routing and Forwarding), which
      allows the segmentation of routing paths without using multiple
      devices.  There are some semantic kinks to work out still, but
      this is a reasonably strong foundation.  From David Ahern.

   3) Remove spinlock fro act_bpf fast path, from Alexei Starovoitov.

   4) Ignore route nexthops with a link down state in ipv6, just like
      ipv4.  From Andy Gospodarek.

   5) Remove spinlock from fast path of act_gact and act_mirred, from
      Eric Dumazet.

   6) Document the DSA layer, from Florian Fainelli.

   7) Add netconsole support to bcmgenet, systemport, and DSA.  Also
      from Florian Fainelli.

   8) Add Mellanox Switch Driver and core infrastructure, from Jiri
      Pirko.

   9) Add support for "light weight tunnels", which allow for
      encapsulation and decapsulation without bearing the overhead of a
      full blown netdevice.  From Thomas Graf, Jiri Benc, and a cast of
      others.

  10) Add Identifier Locator Addressing support for ipv6, from Tom
      Herbert.

  11) Support fragmented SKBs in iwlwifi, from Johannes Berg.

  12) Allow perf PMUs to be accessed from eBPF programs, from Kaixu Xia.

  13) Add BQL support to 3c59x driver, from Loganaden Velvindron.

  14) Stop using a zero TX queue length to mean that a device shouldn't
      have a qdisc attached, use an explicit flag instead.  From Phil
      Sutter.

  15) Use generic geneve netdevice infrastructure in openvswitch, from
      Pravin B Shelar.

  16) Add infrastructure to avoid re-forwarding a packet in software
      that was already forwarded by a hardware switch.  From Scott
      Feldman.

  17) Allow AF_PACKET fanout function to be implemented in a bpf
      program, from Willem de Bruijn"

Pull device mapper update from Mike Snitzer:

 - a couple small cleanups in dm-cache, dm-verity, persistent-data's
   dm-btree, and DM core.

 - a 4.1-stable fix for dm-cache that fixes the leaking of deferred bio
   prison cells

 - a 4.2-stable fix that adds feature reporting for the dm-stats
   features added in 4.2

 - improve DM-snapshot to not invalidate the on-disk snapshot if
   snapshot device write overflow occurs; but a write overflow triggered
   through the origin device will still invalidate the snapshot.

 - optimize DM-thinp's async discard submission a bit now that late bio
   splitting has been included in block core.

 - switch DM-cache's SMQ policy lock from using a mutex to a spinlock;
   improves performance on very low latency devices (eg. NVMe SSD).

 - document DM RAID 4/5/6's discard support

[ I did not pull the slab changes, which weren't appropriate for this
  tree, and weren't obviously the right thing to do anyway.  At the very
  least they need some discussion and explanation before getting merged.

  Because not pulling the actual tagged commit but doing a partial pull
  instead, this merge commit thus also obviously is missing the git
  signature from the original tag ]

Pull core block updates from Jens Axboe:
 "This first core part of the block IO changes contains:

   - Cleanup of the bio IO error signaling from Christoph.  We used to
     rely on the uptodate bit and passing around of an error, now we
     store the error in the bio itself.

   - Improvement of the above from myself, by shrinking the bio size
     down again to fit in two cachelines on x86-64.

   - Revert of the max_hw_sectors cap removal from a revision again,
     from Jeff Moyer.  This caused performance regressions in various
     tests.  Reinstate the limit, bump it to a more reasonable size
     instead.

   - Make /sys/block/<dev>/queue/discard_max_bytes writeable, by me.
     Most devices have huge trim limits, which can cause nasty latencies
     when deleting files.  Enable the admin to configure the size down.
     We will look into having a more sane default instead of UINT_MAX
     sectors.

   - Improvement of the SGP gaps logic from Keith Busch.

   - Enable the block core to handle arbitrarily sized bios, which
     enables a nice simplification of bio_add_page() (which is an IO hot
     path).  From Kent.

   - Improvements to the partition io stats accounting, making it
     faster.  From Ming Lei.

   - Also from Ming Lei, a basic fixup for overflow of the sysfs pending
     file in blk-mq, as well as a fix for a blk-mq timeout race
     condition.

   - Ming Lin has been carrying Kents above mentioned patches forward
     for a while, and testing them.  Ming also did a few fixes around
     that.

   - Sasha Levin found and fixed a use-after-free problem introduced by
     the bio->bi_error changes from Christoph.

Pull power management and ACPI updates from Rafael Wysocki:
 "From the number of commits perspective, the biggest items are ACPICA
  and cpufreq changes with the latter taking the lead (over 50 commits).

  On the cpufreq front, there are many cleanups and minor fixes in the
  core and governors, driver updates etc.  We also have a new cpufreq
  driver for Mediatek MT8173 chips.

  ACPICA mostly updates its debug infrastructure and adds a number of
  fixes and cleanups for a good measure.

  The Operating Performance Points (OPP) framework is updated with new
  DT bindings and support for them among other things.

  We have a few updates of the generic power domains framework and a
  reorganization of the ACPI device enumeration code and bus type
  operations.

  And a lot of fixes and cleanups all over.

  Included is one branch from the MFD tree as it contains some
  PM-related driver core and ACPI PM changes a few other commits are
  based on.

 Most of this is DT contents for new SoCs (or those who have seen new
 device support added). Maybe we should stop separating out the arm64
 contents here to avoid the kind of internal conflicts as we got this
 time around, where 32- and 64-bit contents conflicted.
 
 Anyhow, on the actual contents:
 
 New SoCs:
 
 - Broadcom North Star 2 (ns2)
 - Marvell Berlin4CT
 - Mediatek MT6795
 - Rockchip RK3368
 
 In addition, there are enhancements for the following platforms:
 
 - Mediatek MT8173: cpuidle-dt updates, misc other additions
 - ZyncMP: A bunch of devices added to the existing DTSI
 - Qualcomm MSM8916 and APQ8016 updates for USB, etc.

Pull ARM DT updates from Olof Johansson:
 "Ladies and gentlemen, we proudly announce to you the latest branch of
  ARM device tree contents for the mainline kernel.  Come and see, come
  and see!

  No less than twentythree thousand lines of additions! Just imagine the
  joy you will have of using your mainline kernel on newly supported
  hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
  UniPhier hardware!

  For those of you feeling less adventurous, added hardware support on
  platforms such as TI DM814x and Gumstix Overo platforms might be more
  of your liking.

  We've got something for everyone here!

  Ahem.  Cough.  So, anyway...

  This is the usual large batch of DT updates.  Lots and lots of smaller
  changes, some of the larger ones to point out are:

   - Rockchip veyron (Chromebook) support, as well as several other new boards
   - DRM support on Atmel AT91SAM9N12EK
   - USB additions on some Allwinner platforms
   - Mediatek MT6580 support
   - Freescale i.MX6UL support
   - cleanups for Renesas shmobile platforms
   - lots of added devices on LPC18xx
   - lots of added devices and boards on UniPhier

  There's also some dependent code added here, in particular some
  branches that are primarily merged through the clock tree"

102178108e ARM: SoC driver updates for v4.3 
Some releases this branch is nearly empty, others we have more stuff. It
 tends to gather drivers that need SoC modification or dependencies such
 that they have to (also) go in through our tree.
 
 For this release, we have merged in part of the reset controller tree
 (with handshake that the parts we have merged in will remain stable),
 as well as dependencies on a few clock branches.
 
 In general, new items here are:
 
 - Qualcomm driver for SMM/SMD, which is how they communicate with the
   coprocessors on (some) of their platforms
 - Memory controller work for ARM's PL172 memory controller
 - Reset drivers for various platforms
 - PMU power domain support for Marvell platforms
 - Tegra support for T132/T210 SoCs: PMC, fuse, memory controller per-SoC support

c5fc249862 ARM: SoC cleanups for v4.3 
A large cleanup branch this release, with a healthy 10k negative line delta.
 
 Most of this is removal of legacy (non-DT) support of shmobile
 platforms. There is also removal of two non-DT platforms on OMAP,
 and the plat-samsung directory is cleaned out by moving most of the
 previously shared-location-but-not-actually-shared files from there to
 the appropriate mach directories instead.
 
 There are other sets of changes in here as well:
 
  - Rob Herring removed use of set_irq_flags under all platforms and
    moved to genirq alternatives
  - A series of timer API conversions to set-state interface
  - ep93xx, nomadik and ux500 cleanups from Linus Walleij
  - __init annotation fixes from Nicolas Pitre

6bfb7c7434 cpufreq: remove redundant CPUFREQ_INCOMPATIBLE notifier event 
What's being done from CPUFREQ_INCOMPATIBLE, can also be done with
CPUFREQ_ADJUST. There is nothing special with CPUFREQ_INCOMPATIBLE
notifier.

Kill CPUFREQ_INCOMPATIBLE and fix its usage sites.

This also updates the numbering of notifier events to remove holes.

     otherwise result.

   - privatize smp_mb__after_unlock_lock().

     kernel/rcu/tree.h, in recognition of the fact that RCU is the only
     thing using this, that nothing else is likely to use it, and that
     it is likely to go away completely.

f36fc04e4c The clk framework changes for 4.3 are mostly updates to existing drivers 
and the addition of new clock drivers. Stephen Boyd has also done a lot
 of subsystem-wide driver clean-ups (thanks!). There are also fixes to
 the framework core and changes to better split clock provider drivers
 from clock consumer drivers.

cf9d615f7f regulator: Updates for v4.3 
The biggest changes in the core this time around have been some
 refactorings that move us towards being able to drop the list of
 regulators maintained by the core and instead just use the driver model
 list maintained for the class devices for regulators which will make the
 code smaller and avoid some potential bugs.  Otherwise another fairly
 quiet release for the regulator API, highlights include:
 
  - A new API for setting voltages based on a minimum, target, maximum
    triplet.
  - Support for continuous voltage ranges rather than tables of explicit
    steps in the PWM regulator, requiring less explicit configuration.
  - New driver support for Dialog DA9215, Maxim 77843, Mediatek MT6311
    and Qualcomm RPM.

c2078402e4 TTY/Serial driver patches for 4.3-rc1 
Here is the big tty/serial driver update for 4.3-rc1.
 
 Not many major things, a number of driver updates and changes, and the
 8250 driver got split up a bit to make it easier to work with by moving
 some functions to a new file.  Full details are in the shortlog.
 
 All have been in linux-next with no reported issues.

87583ebb9f IGMP: Document igmp_link_local_mcast_reports 
Document the addition of a new sysctl variable which controls the
generation of IGMP reports for link local multicast groups in the
224.0.0.X range.

IGMP reports for local multicast groups can now be optionally
inhibited by setting the value to zero e.g.:
echo 0 > /proc/sys/net/ipv4/igmp_link_local_mcast_reports

To retain backwards compatibility the previous behaviour is retained
by default on system boot or reverted by setting the value back to
non-zero.

66099bb0ee md-cluster: fix deadlock issue on message lock 
There is problem with previous communication mechanism, and we got below
deadlock scenario with cluster which has 3 nodes.

	Sender                	    Receiver        		Receiver

	token(EX)
       message(EX)
      writes message
   downconverts message(CR)
      requests ack(EX)
		                  get message(CR)            gets message(CR)
                		  reads message                reads message
		               requests EX on message    requests EX on message

To fix this problem, we do the following changes:

1. the sender downconverts MESSAGE to CW rather than CR.
2. and the receiver request PR lock not EX lock on message.

And in case we failed to down-convert EX to CW on message, it is better to
unlock message otherthan still hold the lock.
