6b5e09a748 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 
Pull networking fixes from David Miller:

 1) Netfilter list handling fix, from Linus.

 2) RXRPC/AFS bug fixes from David Howells (oops on call to serviceless
    endpoints, build warnings, missing notifications, etc.) From David
    Howells.

 3) Kernel log message missing newlines, from Colin Ian King.

 4) Don't enter direct reclaim in netlink dumps, the idea is to use a
    high order allocation first and fallback quickly to a 0-order
    allocation if such a high-order one cannot be done cheaply and
    without reclaim. From Eric Dumazet.

 5) Fix firmware download errors in btusb bluetooth driver, from Ethan
    Hsieh.

 6) Missing Kconfig deps for QCOM_EMAC, from Geert Uytterhoeven.

 7) Fix MDIO_XGENE dup Kconfig entry. From Laura Abbott.

 8) Constrain ipv6 rtr_solicits sysctl values properly, from Maciej
    Żenczykowski.

35ff96dfd3 MTD updates for 4.9-rc1 
NAND:
 
  * Add the infrastructure to automate NAND timings configuration
  * Provide a generic DT property to maximize ECC strength
  * Some refactoring in the core bad block table handling, to help with
    improving some of the logic in error cases.
  * Minor cleanups and fixes
 
 MTD:
 
  * Add APIs for handling page pairing; this is necessary for reliably
    supporting MLC and TLC NAND flash, where paired-page disturbance affects
    reliability. Upper layers (e.g., UBI) should make use of these in the near
    future.

00e729c933 ARM: DT updates for v4.9 
These are as usual a very large number of mostly boring updates to
 enable devices in existing machines, or to fix minor bugs.  Notably,
 an ongoing treewide effort to fix warnings caused by an update to the
 device tree compiler. These are enabled with "make W=1" at the moment
 but can hopefully become the default once all issues have been addressed.
 
 No new SoC platform is added this time around (Armada 395 and Orion
 mv88f5181 are slight variations of existing ones), but a significant
 number of new dts files are added, which I list by platform:
 
 - Allwinner: Empire Electronix M712 and iNet d978 Rev2 tablets;
 	Orange Pi PC Plus, Orange Pi 2, Orange Pi Plus 2E,
 	Orange Pi Lite, Olimex A33-Olinuxino, and Nano Pi Neo
 	single-board computers

 - The Qualcomm external bus interface 2 (EBI2), used in some of their
   mobile phone chips for connecting flash memory, LCD displays or
   other peripherals
 
 - Secure monitor firmware for Amlogic SoCs, and an NVMEM driver for the
   EFUSE based on that firmware interface.
 
 - Perf support for the AppliedMicro X-Gene performance monitor unit
 
 - Reset driver for STMicroelectronics STM32
 
 - Reset driver for SocioNext UniPhier SoCs
 
 Aside from these, there are minor updates to SoC-specific bus,
 clocksource, firmware, pinctrl, reset, rtc and pmic drivers.

66f2c6d952 ARM: SoC platform updates for v4.9 
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - We get support for running in big-endian mode on two platforms:
   sunxi (Allwinner) and s3c24xx (old Samsung).
 
 - The recently added Uniphier platform now uses standard PSCI
   methods for SMP booting and we remove support for old bootloader
   versions that did not support it yet.
 
 - In sunxi, we gain support for the "Nextthing GR8" SoC, which
   is a close relative of the Allwinner A13 and R8 chips.
 
 - PXA completes its move over to the generic dmaengine framework
   and removes its old private API
 
 - mach-bcm gains support for BCM47189/BCM53573, their first ARM
   SoC with integrated 802.11ac wireless networking.

Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC platform updates from Arnd Bergmann:
 "These are updates for platform specific code on 32-bit ARM machines,
  essentially anything that can not (yet) be expressed using DT files.

  Noteworthy changes include:

   - We get support for running in big-endian mode on two platforms:
     sunxi (Allwinner) and s3c24xx (old Samsung).

   - The recently added Uniphier platform now uses standard PSCI methods
     for SMP booting and we remove support for old bootloader versions
     that did not support it yet.

   - In sunxi, we gain support for the "Nextthing GR8" SoC, which is a
     close relative of the Allwinner A13 and R8 chips.

   - PXA completes its move over to the generic dmaengine framework and
     removes its old private API

   - mach-bcm gains support for BCM47189/BCM53573, their first ARM SoC
     with integrated 802.11ac wireless networking"

Pull block layer updates from Jens Axboe:
 "This is the main pull request for block layer changes in 4.9.

  As mentioned at the last merge window, I've changed things up and now
  do just one branch for core block layer changes, and driver changes.
  This avoids dependencies between the two branches. Outside of this
  main pull request, there are two topical branches coming as well.

  This pull request contains:

   - A set of fixes, and a conversion to blk-mq, of nbd. From Josef.

   - Set of fixes and updates for lightnvm from Matias, Simon, and Arnd.
     Followup dependency fix from Geert.

   - General fixes from Bart, Baoyou, Guoqing, and Linus W.

   - CFQ async write starvation fix from Glauber.

   - Add supprot for delayed kick of the requeue list, from Mike.

   - Pull out the scalable bitmap code from blk-mq-tag.c and make it
     generally available under the name of sbitmap. Only blk-mq-tag uses
     it for now, but the blk-mq scheduling bits will use it as well.
     From Omar.

   - bdev thaw error progagation from Pierre.

   - Improve the blk polling statistics, and allow the user to clear
     them. From Stephen.

   - Set of minor cleanups from Christoph in block/blk-mq.

   - Set of cleanups and optimizations from me for block/blk-mq.

4dfddf5036 SCSI misc on 20161006 
This update includes the usual round of major driver updates (hpsa, be2iscsi,
 hisi_sas, zfcp, cxlflash).  There's a new incarnation of hpsa called smartpqi
 for which a driver is added, there's some cleanup work of the ibm vscsi target
 and updates to libfc, plus a whole host of minor fixes and updates and finally
 the removal of several ISA drivers which seem not to have been used for years.

4c1fad64ef In this round, we've investigated how f2fs deals with errors given by our fault 
injection facility. With this, we could fix several corner cases. And, in order
 to improve the performance, we set inline_dentry by default and enhance the
 exisiting discard issue flow. In addition, we added f2fs_migrate_page for better
 memory management.
 
 = Enhancement =
  - set inline_dentry by default
  - improve discard issue flow
  - add more fault injection cases in f2fs
  - allow block preallocation for encrypted files
  - introduce migrate_page callback function
  - avoid truncating the next direct node block at every checkpoint
 
 = Bug fixes =
  - set page flag correctly between write_begin and write_end
  - missing error handling cases detected by fault injection
  - preallocate blocks regarding to 4KB alignement correctly
  - dentry and filename handling of encryption
  - lost xattrs of directories

Pull xfs and iomap updates from Dave Chinner:
 "The main things in this update are the iomap-based DAX infrastructure,
  an XFS delalloc rework, and a chunk of fixes to how log recovery
  schedules writeback to prevent spurious corruption detections when
  recovery of certain items was not required.

  The other main chunk of code is some preparation for the upcoming
  reflink functionality. Most of it is generic and cleanups that stand
  alone, but they were ready and reviewed so are in this pull request.

  Speaking of reflink, I'm currently planning to send you another pull
  request next week containing all the new reflink functionality. I'm
  working through a similar process to the last cycle, where I sent the
  reverse mapping code in a separate request because of how large it
  was. The reflink code merge is even bigger than reverse mapping, so
  I'll be doing the same thing again....

   - change of XFS mailing list to linux-xfs@vger.kernel.org

41844e3620 Staging/IIO patches for 4.9-rc1 
Here is the big staging and IIO driver pull request for 4.9-rc1.
 
 There are a lot of patches in here, the majority due to the
 drivers/staging/greybus/ subsystem being merged in with full development
 history that went back a few years, in order to preserve the work that
 those developers did over time.  This was done the same way that btrfs
 was merged into the tree, so all should be ok there.
 
 Lots and lots of tiny cleanups happened in the tree as well, due to the
 Outreachy application process and lots of other developers showing up
 for the first time to clean code up.  Along with those changes, we
 deleted a wireless driver, and added a raspberrypi driver (currently
 marked broken), and lots of new iio drivers.
 
 Overall the tree still shrunk with more lines removed than added, about
 10 thousand lines removed in total.  Full details are in the very long
 shortlog below.
 
 All of this has been in the linux-next tree with no issues.  There will
 be some merge problems with other subsystem trees, but those are all
 minor problems and shouldn't be hard to work out when they happen
 (MAINTAINERS and some lustre build problems with the IB tree.)

And furter from me asking for clarification about greybus:
 "Right now there is a phone from Motorola shipping with this code (a
  slightly older version, but the same tree), so even though Ara is not
  alive in the same form, the functionality is happening. We are working
  with the developers of that phone to merge the newer stuff in with
  their fork so they can use the upstream version in future versions of
  their phone product line.

  Toshiba has at least one chip shipping in their catalog that
  needs/uses this protocol over a Unipro link, and rumor has it that
  there might be more in the future.

  There are also other users of the greybus protocols, there is a talk
  next week at ELC that shows how it is being used across a network
  connection to control a device, and previous ELC talks have showed the
  protocol stack being used over USB to drive embedded Linux boards.
  I've also talked to some people who are starting to work to add a host
  controller driver to control arduinos as the greybus PHY protocols are
  very useful to control a serial/i2c/spio/whatever device across a
  random physical link, as it is a way to have a self-describing device
  be attached to a host without needing manual configuration.

  So yes, people are using it, and there is still the chance that it
  will show up in a phone/laptop/tablet/whatever from Google in the
  future as well, the tech isn't dead, even if the original large phone
  project happens to be"

Linus Torvalds
6a497e9d58 This is the bulk of GPIO changes for the v4.9 series: 
Subsystem improvements:
 
 - Do away with the last users of the obsolete Kconfig options
   ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
   always sounded like an item on a wishlist to Santa Claus to
   me). We can now select GPIOLIB and be done with it, for all
   archs. After some struggle it even work on UM. Not that it has
   GPIO, but if it wants to, it can select the library.
 
 - Continued efforts to make drivers properly either tristate or
   bool.
 
 - Introduce a warning for drivers assigning default triggers to
   their irqchip lines when probed from device tree, so we find and
   fix these ambigous drivers. It is agreed that in the OF config
   path, the device tree defines trigger characteristics.
 
 - The same warning, mutatis mutandis, for ACPI-probed GPIO
   irqchips.
 
 - We introduce the ability to mark certain IRQ lines as "unusable"
   as they can be taken by BIOS/firmware, unrouted in silicon and
   generally nasty if you use them, and such things. This is
   put to good use in the STMPE driver and also in the Cherryview
   pin control driver.
 
 - A new "mockup" virtual GPIO device that can be used for testing.
   The plan is to add unit tests under tools/* for exercising this
   device and verify that the kernel code paths are working as they
   should.
 
 - Make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
   implicit all the time, but when people started building UM
   with allyesconfig or allmodconfig it exploded in their face.
 
 - Move some stray bits of device tree and ACPI HW description
   callbacks down into their respective implementation silo. These
   were causing issues when compiling on !HAS_IOMEM as well, so
   now eventually UM compiles the GPIOLIB library if it wants to.
 
 New drivers:
 
 - New driver for the Aspeed GPIO front-end companion to the
   pin controller merged through the pin control tree.
 
 - New driver for the LP873x PMIC GPIO portions.
 
 - New driver for Technologic Systems' I2C FPGA GPIO such as
   TS4900, TS-7970, TS-7990 and TS-4100.
 
 - New driver for the Broadcom BCM63xx series including BCM6338
   and BCM6345.
 
 - New driver for the Intel WhiskeyCove PMIC GPIO.
 
 - New driver for the Allwinner AXP209 PMIC GPIO portions.
 
 - New driver for Diamond Systems 48 line GPIO-MM, another of
   these port-mapped I/O expansion cards.
 
 - Support the STMicroelectronics STMPE1600 variant in the STMPE
   driver.
 
 Driver improvements:
 
 - The STMPE driver now supports rising/falling edge detection
   properly for IRQs.
 
 - The PCA954x will now fetch and enable its VCC regulator properly.
 
 - Major rework of the PCA953x driver with the goal of eventually
   switching it over to use regmap and thus modernize it even more.
 
 - Switch the IOP driver to use the generic MMIO GPIO library.
 
 - Move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
   over to this subsystem from MFD, achieveing some separation of
   concerns.

Merge tag 'gpio-v4.9-1' 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 v4.9 series:

  Subsystem improvements:

   - do away with the last users of the obsolete Kconfig options
     ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
     always sounded like an item on a wishlist to Santa Claus to me). We
     can now select GPIOLIB and be done with it, for all archs. After
     some struggle it even work on UM. Not that it has GPIO, but if it
     wants to, it can select the library.

   - continued efforts to make drivers properly either tristate or bool.

   - introduce a warning for drivers assigning default triggers to their
     irqchip lines when probed from device tree, so we find and fix
     these ambigous drivers. It is agreed that in the OF config path,
     the device tree defines trigger characteristics.

   - the same warning, mutatis mutandis, for ACPI-probed GPIO irqchips.

   - we introduce the ability to mark certain IRQ lines as "unusable" as
     they can be taken by BIOS/firmware, unrouted in silicon and
     generally nasty if you use them, and such things. This is put to
     good use in the STMPE driver and also in the Cherryview pin control
     driver.

   - a new "mockup" virtual GPIO device that can be used for testing.
     The plan is to add unit tests under tools/* for exercising this
     device and verify that the kernel code paths are working as they
     should.

   - make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
     implicit all the time, but when people started building UM with
     allyesconfig or allmodconfig it exploded in their face.

   - move some stray bits of device tree and ACPI HW description
     callbacks down into their respective implementation silo. These
     were causing issues when compiling on !HAS_IOMEM as well, so now
     eventually UM compiles the GPIOLIB library if it wants to.

  New drivers:

   - new driver for the Aspeed GPIO front-end companion to the pin
     controller merged through the pin control tree.

   - new driver for the LP873x PMIC GPIO portions.

   - new driver for Technologic Systems' I2C FPGA GPIO such as TS4900,
     TS-7970, TS-7990 and TS-4100.

   - new driver for the Broadcom BCM63xx series including BCM6338 and
     BCM6345.

   - new driver for the Intel WhiskeyCove PMIC GPIO.

   - new driver for the Allwinner AXP209 PMIC GPIO portions.

   - new driver for Diamond Systems 48 line GPIO-MM, another of these
     port-mapped I/O expansion cards.

   - support the STMicroelectronics STMPE1600 variant in the STMPE
     driver.

  Driver improvements:

   - the STMPE driver now supports rising/falling edge detection
     properly for IRQs.

   - the PCA954x will now fetch and enable its VCC regulator properly.

   - major rework of the PCA953x driver with the goal of eventually
     switching it over to use regmap and thus modernize it even more.

   - switch the IOP driver to use the generic MMIO GPIO library.

   - move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
     over to this subsystem from MFD, achieveing some separation of
     concerns"

02bafd96f3 This is the documentation update pull for the 4.9 merge window. 
The Sphinx transition is still creating a fair amount of work.  Here we
 have a number of fixes and, importantly, a proper PDF output solution,
 thanks to Jani Nikula, Mauro Carvalho Chehab and Markus Heiser.
 
 I've started a couple of new books: a driver API book (based on the old
 device-drivers.tmpl) and a development tools book.  Both are meant to show
 how we can integrate together our existing documentation into a more
 coherent and accessible whole.  It involves moving some stuff around and
 formatting changes, but, I think, the results are worth it.  The good news
 is that most of our existing Documentation/*.txt files are *almost* in RST
 format already; the amount of messing around required is minimal.
 
 And, of course, there's the usual set of updates, typo fixes, and more.

5617c122e6 The core clk framework changes are small again. They're mostly minor fixes 
that weren't causing enough problems (or any problems when we're just
 clarifying things) to warrant sending outside the merge window. The
 majority of changes are in drivers for various SoCs. Full details
 are in the logs, but here's the summary.
 
 Core:
 
  - Better support for DeviceTree overlays with the addition of the
    CLK_OF_DECLARE_DRIVER macro. Now we won't probe a clk driver
    for a device node that matched during of_clk_init(), unless
    the driver uses CLK_OF_DECLARE_DRIVER instead of CLK_OF_DECLARE.
    This allows overlays to work cleanly for drivers that must probe
    before the device model is ready, and also after it's ready
    when an overlay is loaded.
 
  - Clarification in the code around how clk_hw pointers are returned
    from of clk providers
 
  - Proper migration of prepare/enable counts to parents when the
    clk tree is constructed
 
 New Drivers:
 
  - Socionext's UniPhier SoCs
  - Loongson1C
  - ZTE ZX296718
  - Qualcomm MDM9615
  - Amlogic GXBB AO clocks and resets
  - Broadcom BCM53573 ILP
  - Maxim MAX77620
 
 Updates:
 
  - Four Allwinner SoCs are migrated to the new style clk driver (A31, A31s,
    A23 and A33)
  - Exynos 5xxx audio and DRAM clks
  - Loongson1B AC97, DMA and NAND clks
  - Rockchip DDR clks and rk3399 driver tweaks
  - Renesas R-Car M3-W (r8a7796) SoC SDHI interface and Watchdog timer clks
  - Renasas R-Car H3 and M3-W CMT clks and RAVB+Thermal clks for M3-W
  - Amlogic GXBB MMC gate clks
  - at91 sama5d4 sckc
  - Removal of STiH415 and STiH416 clk support as the SoC is being removed
  - Rework of STiH4xx clk support for new style bindings
  - Continuation of driver migration to clk_hw based registration APIs
  - xgene PMD support
  - bcm2835 critical clk markings
  - ARM versatile ICST

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk framework updates from Stephen Boyd:
 "The core clk framework changes are small again. They're mostly minor
  fixes that weren't causing enough problems (or any problems when we're
  just clarifying things) to warrant sending outside the merge window.
  The majority of changes are in drivers for various SoCs. Full details
  are in the logs, but here's the summary.

  Core:

   - Better support for DeviceTree overlays with the addition of the
     CLK_OF_DECLARE_DRIVER macro. Now we won't probe a clk driver for a
     device node that matched during of_clk_init(), unless the driver
     uses CLK_OF_DECLARE_DRIVER instead of CLK_OF_DECLARE. This allows
     overlays to work cleanly for drivers that must probe before the
     device model is ready, and also after it's ready when an overlay is
     loaded.

   - Clarification in the code around how clk_hw pointers are returned
     from of clk providers

   - Proper migration of prepare/enable counts to parents when the clk
     tree is constructed

  New Drivers:

   - Socionext's UniPhier SoCs
   - Loongson1C
   - ZTE ZX296718
   - Qualcomm MDM9615
   - Amlogic GXBB AO clocks and resets
   - Broadcom BCM53573 ILP
   - Maxim MAX77620

 Updates:

   - Four Allwinner SoCs are migrated to the new style clk driver (A31,
     A31s, A23 and A33)
   - Exynos 5xxx audio and DRAM clks
   - Loongson1B AC97, DMA and NAND clks
   - Rockchip DDR clks and rk3399 driver tweaks
   - Renesas R-Car M3-W (r8a7796) SoC SDHI interface and Watchdog timer
     clks
   - Renasas R-Car H3 and M3-W CMT clks and RAVB+Thermal clks for M3-W
   - Amlogic GXBB MMC gate clks
   - at91 sama5d4 sckc
   - Removal of STiH415 and STiH416 clk support as the SoC is being
     removed
   - Rework of STiH4xx clk support for new style bindings
   - Continuation of driver migration to clk_hw based registration APIs
   - xgene PMD support
   - bcm2835 critical clk markings
   - ARM versatile ICST"

   - ... various fixes, cleanups and smaller enhancements.

     e.g.:

     $ perf record -e '{cycles,instructions}' make

      0.76%   0.00%[.] strlen

   - Add branch stack / basic block info to 'perf annotate --stdio',
     where for each branch, we add an asm comment after the instruction
     with information on how often it was taken and predicted. See
     example with color output at:

       http://vger.kernel.org/~acme/perf/annotate_basic_blocks.png

     (Peter Zijlstra)

   - Add support for using symbols in address filters with Intel PT and
     ARM CoreSight (hardware assisted tracing facilities) (Adrian
     Hunter, Mathieu Poirier)

   - Add support for interacting with Coresight PMU ETMs/PTMs, that are
     IP blocks to perform hardware assisted tracing on a ARM CPU core
     (Mathieu Poirier)

   - Support generating cross arch probes, i.e. if you specify a vmlinux
     file for different arch than the one in the host machine,

        $ perf probe --definition function_name args

     will generate the probe definition string needed to append to the
     target machine /sys/kernel/debug/tracing/kprobes_events file, using
     scripting (Masami Hiramatsu).

   - Allow configuring the default 'perf report -s' sort order in
     ~/.perfconfig, for instance, "sym,dso" may be more fitting for
     kernel developers. (Arnaldo Carvalho de Melo)

72ec94560d Power management material for v4.9-rc1 
- Add a mechanism for passing hints from the scheduler to cpufreq governors
    via their utilization update callbacks and use it to introduce "IOwait
    boosting" into the schedutil governor and intel_pstate that will make them
    boost performance if the enqueued task was previously waiting on I/O
    (Rafael Wysocki).
 
  - Fix a schedutil governor problem that causes it to overestimate utilization
    if SMT is in use (Steve Muckle).
 
  - Update defconfigs trying to use the schedutil governor as a module which is
    not possible any more (Javier Martinez Canillas).
 
  - Update the intel_pstate's pstate_sample tracepoint to take "IOwait boosting"
    into account (Srinivas Pandruvada).

    up and update its Kconfig description (Viresh Kumar).
 
  - Add support for more ARM platforms to the cpufreq-dt driver (Chanwoo Choi,

    Markus Elfring).
 
  - Constify some local structures in the intel_pstate driver (Julia Lawall).

  - Add support for PM domain removal to the generic power domains (genpd)
    framework, add new DT helper functions to it and make it always enable
    debugfs support if available (Jon Hunter, Tomeu Vizoso).

    suspend operations have not been registered (Sudeep Holla).
 
  - Make it possible to use hibernation with PAGE_POISONING_ZERO enabled

Pull power management updates from Rafael Wysocki:
 "Traditionally, cpufreq is the area with the greatest number of
  changes, but there are fewer of them than last time. There also is
  some activity in the generic power domains and the devfreq frameworks,
  a couple of system suspend and hibernation fixes and some assorted
  changes in other places.

  One new feature is the cpufreq change to allow the scheduler to pass
  hints to the governors' utilization update callbacks and some code
  rework based on that. Another one is the support for domain removal in
  the generic power domains framework. Also it is now possible to use
  hibernation with PAGE_POISONING_ZERO enabled and devfreq supports the
  RockChip DFI controller and the rk3399 DMC.

  The rest of the changes is mostly fixes and cleanups in a number of
  places.

  Specifics:

     governors via their utilization update callbacks and use it to

Pull arm64 updates from Will Deacon:
 "It's a bit all over the place this time with no "killer feature" to
  speak of.  Support for mismatched cache line sizes should help people
  seeing whacky JIT failures on some SoCs, and the big.LITTLE perf
  updates have been a long time coming, but a lot of the changes here
  are cleanups.

  We stray outside arch/arm64 in a few areas: the arch/arm/ arch_timer
  workaround is acked by Russell, the DT/OF bits are acked by Rob, the
  arch_timer clocksource changes acked by Marc, CPU hotplug by tglx and
  jump_label by Peter (all CC'd).

  Summary:

   - Support for execute-only page permissions
   - Support for hibernate and DEBUG_PAGEALLOC
   - Support for heterogeneous systems with mismatches cache line sizes
