      Pull ARC updates from Vineet Gupta:
       "We have a relatively big changeset for ARC for 4.7.
      
        The highlight is support for EZChip (now Mellanox) NPS-400 network
        processor, a 400-Gb throughput C-programmable packet processor based
        on ARC700 cores from Synopsys. See
      
              http://www.mellanox.com/related-docs/prod_npu/PB_NPS-400.pdf
      
        Also present are irqchip and clocksource drivers for NPS as agreed
        with respective maintainers to go via ARC tree due to an soc header
        dependency.  I have the needed ACKs from Jason, Marc, Daniel.  You
        might run into a trivial merge conflict in drivers/irqchip/*
      
        This EZChip platform support required some deep changes in ARC
        architecture code and also opportunity to cleanup past sins (legacy
        irq domains, missing irq domain lookup, hard coded timer irqs...)
      
        Summary:
      
         - Support for EZChip (now Mellanox) NPS-400 Network processor based
           on ARC700
      
         - NPS interrupt controller and clocksource drivers
      
         - ARC timers probed off DT
      
         - ARC iqrchips switching to linear domain (upgrade from legacy
           domains)"

      Pull security subsystem updates from James Morris:
       "Highlights:
      
         - A new LSM, "LoadPin", from Kees Cook is added, which allows forcing
           of modules and firmware to be loaded from a specific device (this
           is from ChromeOS, where the device as a whole is verified
           cryptographically via dm-verity).
      
           This is disabled by default but can be configured to be enabled by
           default (don't do this if you don't know what you're doing).
      
         - Keys: allow authentication data to be stored in an asymmetric key.
           Lots of general fixes and updates.
      
         - SELinux: add restrictions for loading of kernel modules via
           finit_module().  Distinguish non-init user namespace capability
           checks.  Apply execstack check on thread stacks"

      Linus Torvalds authored
      Pull tracing updates from Steven Rostedt:
       "This includes two new updates for the ftrace infrastructure.
      
         - With the changing of the code for filtering events by pid, from a
           list of pids to a bitmask, we can now easily implement following
           forks.  With a new tracing option "event-fork" which, when set,
           will have tasks with pids in set_event_pid, when they fork, to have
           their child pids added to set_event_pid and the child will be
           traced as well.
      
           Note, if "event-fork" is set and a task with its pid in
           set_event_pid exits, its pid will be removed from set_event_pid
      
         - The addition of Tom Zanussi's hist triggers.  This includes a very
           thorough documentatino on how to use the hist triggers with events.
           This introduces a quick and easy way to get histogram data from
           events and their fields.
      
        Some other cleanups and updates were added as well.  Like Masami
        Hiramatsu added test cases for the event trigger and hist triggers.
        Also I added a speed up of filtering by using a temp buffer when
        filters are set"

        the drivers/ directory but got merged through arm-soc for practical
        reasons.
      
        For the most part, this is now related to power management
        controllers, which have not yet been abstracted into a separate
        subsystem, and typically require some code in drivers/soc or arch/arm
        to control the power domains.
      
        Another large chunk here is a rework of the NVIDIA Tegra USB3.0
        support, which was surprisingly tricky and took a long time to get

      Pull ARM 64-bit DT updates from Arnd Bergmann:
       "We continue ramping up platform support for 64-bit ARM machines, with
        111 individual non-merge changesets touching 21 platforms.
      
        The LG1312 platform is completely new and is the first ARM platform by
        LG that we support in the mainline kernel.  Two other SoCs got added
        that are updated versions of existing SoC families, so the port mainly
        consists of new dts files:
      
         - The Hisilicon Hip06/D03 is the latest server platform from
           Huawei/Hisilicon, and follows the Hip05/D02 platform.
      
         - Rockchip RK3399 follows the 32-bit RK3288 that is popular in
           low-end Chromebooks and the 64-bit RK3368 that is mainly found in
           chinese Android TV boxes.
      
        The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620) gets a
        long-awaited overhaul with a lot of devices enabled in the DT, so it
        should be much more usable with a mainline kernel now.  See also
      
           https://plus.google.com/111524780435806926688/posts/PeGb2VsNhJd
      
        A lot of work went into enabling new device drivers on existing
        machines, but we also have a couple of new commercially available
        machines:
      
         - Google Pixel C laptop based on Tegra210
         - Hardkernel Odroid C2 Based on Amlogic Meson GXBB (S905)
         - Geekbuying GeekBox based on Rockchip RK3368
      
        And finally, a couple of reference or development platforms that are
        not end-user platforms but are used for trying out the respective SoC
        platforms:
      
         - Amlogic Meson GXBB P200 and P201 development systems
         - NXP Layerscape 1043A QDS development board
         - Hisilicon Hip06 D03 server board, as mentioned above

      Pull ARM DT updates from Arnd Bergmann:
       "These are all the updates to device tree files for 32-bit platforms,
        which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
        changesets, 450 files changed, 23340 insertions, 5216 deletions.
      
        The three platforms that are added with the "soc" branch are here as
        well, and we add some related machine files:
      
         - For Aspeed AST2400/AST2500, we get the evaluation platform and the
           Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
         - For Oxnas 810SE, the Western Digital "My Book World Edition" is
           added as the only platform at the moment.
         - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7) are
           supported
      
        On the ARM Realview development platform, we now support all machines
        with device tree, previously only the board files were supported,
        which in turn will likely be removed soon.
      
        Qualcomm IPQ4019 is the second generation ARM based "Internet
        Processor", following the IPQ806x that is used in many high-end WiFi
        routers.  This one integrates two ath10k wifi radios that were
        previously on separate chips.
      
        Other boards that got added for existing chips are:
      
        Ti OMAP family:
           - Amazon Kindle Fire, first generation, tablet and ebook reader
           - OnRISC Baltos iR 2110 and 3220 embedded industrial PCs

        the Kconfig statement is the main relevant milestone for a new
        platform.  In each case, some drivers are are shared with existing
        platforms, while other drivers are added for v4.7 as well, or come in
        a later release.
      
         - The Aspeed platform is probably the most interesting one, this is
           what most whitebox servers use as their baseboard management
           controller.  We get support for the very common ast2400 and ast2500
           SoCs.  The OpenBMC project focuses on this chip, and the LWN
           article about their ELC 2016 presentation at
      
              https://lwn.net/Articles/683320/
      
           triggered the submission, but the code comes from IBM's OpenPOWER
           team rather than the team at Facebook.  There are still a lot more
           drivers that need to get added over time, and I hope both teams can
           work together on that.
      
         - OXNAS is an old platform for Network Attached Storage devices from
           Oxford Semiconductor.  There are models with ARM10 (!) and
           ARM11MPCore cores, but for now, we only support the original ARM9
           based versions.  The product lineup was subsequently part of PLX,
           Avago and now the new Broadcom Ltd.
      
              https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas
      
           has some more information.
      
         - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M
           cores and is related to the existing Realview / Versatile Express
           lineup, but without MMU.
      
           We now support various NOMMU platforms, so adding a new one is
           fairly straightforward.
      
              http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/
      
           has detailed information about the platform.
      
        Other noteworthy updates:
      
         - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain
           Lemieux are now maintaining the platform.
      
           This is an older ARM9 based platform from NXP (not Freescale), but
           it remains in use in embedded markets.
      
         - Kevin Hilman is now co-maintaining the Amlogic Meson platform for
           both 32-bit and 64-bit ARM, and started contributing some patches.
      
         - As is often the case, work on the OMAP platforms makes up the bulk
           of the actual SoC code changes in arch/arm, but there isn't a lot
           of that either"

      iwlwifi: fix mis-merge that breaks the driver · 0e034f5c
      Linus Torvalds authored
      My laptop that uses the intel 7680 iwlwifi module would no longer
      connects to the network.  It would fail with a "Microcode SW error
      detected." and spew out register state over and over again without ever
      connecting to the network.
      
      The cause is mis-merge in commit 909b27f7, where David seems to have
      lost some of the changes to iwl_mvm_set_tx_cmd() from commit
      5c08b0f5 ("iwlwifi: mvm: don't override the rate with the AMSDU
      len").
      
      The reason seems to be a conflict with commit d8fe4844 ("iwlwifi:
      mvm: add support for new TX CMD API"), which touched a line adjacent to
      the changes in 909b27f7.
      
      David missed the fact that "info->driver_data[0]" had become
      "skb_info->driver_data[0]".  Then he removed the skb_info because it was
      unused.
      
      This just re-updates iwl_mvm_set_tx_cmd() with the lost two lines.

      xfs: concurrent readdir hangs on data buffer locks · 9f541801
      Dave Chinner authored
      There's a three-process deadlock involving shared/exclusive barriers
      and inverted lock orders in the directory readdir implementation.
      It's a pre-existing problem with lock ordering, exposed by the
      VFS parallelisation code.
      
      process 1               process 2               process 3
      ---------               ---------               ---------
      readdir
      iolock(shared)
        get_leaf_dents
          iterate entries
             ilock(shared)

                                                            map, lock buffer
                                                            <blocks>
                              finish ->iterate_shared
                              file_accessed()

              finishes processing buffer
              get next buffer
                ilock(shared)
                <blocks>
      
      And that's the deadlock.
      
      Fix this by dropping the current buffer lock in process 1 before
      trying to map the next buffer. This means we keep the lock order of
      ilock -> buffer lock intact and hence will allow process 3 to make
      progress and drop it's ilock(shared) once it is done.

      arc: axs103_smp: Fix CPU frequency to 100MHz for dual-core · 776d7f16
      Alexey Brodkin authored
      The most recent release of AXS103 [v1.1] is proven to work
      at 100 MHz in dual-core mode so this change uses mentioned feature.
      For that we:
       * Update axc003_idu.dtsi with mention of really-used CPU clock freq
       * Remove clock override in AXS platform code for dual-core HW
      
      Note we're still leaving a hack for clock "downgrade" on early boot
      for quad-core hardware.
      
      Also note this change will break functionality of AXS103 v1.0 hardware.
      That means all users of AXS103 __must__ upgrade their boards with the
      most recent firmware.

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for kernel cycle v4.7:
      
        Core infrastructural changes:
      
         - Support for natively single-ended GPIO driver stages.
      
           This means that if the hardware has registers to configure open
           drain or open source configuration, we use that rather than (as we
           did before) try to emulate it by switching the line to an input to
           get high impedance.
      
           This is also documented throughly in Documentation/gpio/driver.txt
           for those of you who did not understand one word of what I just
           wrote.
      
         - Start to do away with the unnecessarily complex and unitelligible
           ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another
           evolutional artifact from the time when the GPIO subsystem was
           unmaintained.
      
           Archs can now just select GPIOLIB and be done with it, cleanups to
           arches will trickle in for the next kernel.  Some minor archs ACKed
           the changes immediately so these are included in this pull request.
      
         - Advancing the use of the data pointer inside the GPIO device for
           storing driver data by switching the PowerPC, Super-H Unicore and
           a few other subarches or subsystem drivers in ALSA SoC, Input,
           serial, SSB, staging etc to use it.
      
         - The initialization now reads the input/output state of the GPIO
           lines, so that each GPIO descriptor knows - if this callback is
           implemented - whether the line is input or output.  This also
           reflects nicely in userspace "lsgpio".
      
         - It is now possible to name GPIO producer names, line names, from
           the device tree.  (Platform data has been supported for a while).
           I bet we will get a similar mechanism for ACPI one of those days.
           This makes is possible to get sensible producer names for e.g.
           GPIO rails in "lsgpio" in userspace.
      
        New drivers:
      
         - New driver for the Loongson1.
      
         - The XLP driver now supports Broadcom Vulcan ARM64.
      
         - The IT87 driver now supports IT8620 and IT8628.
      
         - The PCA953X driver now supports Galileo Gen2.
      
        Driver improvements:
      
         - MCP23S08 was switched to use the gpiolib irqchip helpers and now
           also suppors level-triggered interrupts.
      
         - 74x164 and RCAR now supports the .set_multiple() callback
      
         - AMDPT was converted to use generic GPIO.
      
         - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
           support the new single ended callback for open drain and in some
           cases open source.
      
         - Implement the .get_direction() callback for a few more drivers like
           PL061, Xgene.
      
        Cleanups:
      
         - Paul Gortmaker combed through the drivers and de-modularized those
           who are not really modules.
      
         - Move the GPIO poweroff DT bindings to the power subdir where they
           belong.
      
         - Rename gpio-generic.c to gpio-mmio.c, which is much more to the
           point.  That's what it is handling, nothing more, nothing less"

      btrfs: Switch to generic xattr handlers · e0d46f5c
      Andreas Gruenbacher authored
      The btrfs_{set,remove}xattr inode operations check for a read-only root
      (btrfs_root_readonly) before calling into generic_{set,remove}xattr.  If
      this check is moved into __btrfs_setxattr, we can get rid of
      btrfs_{set,remove}xattr.
      
      This patch applies to mainline, I would like to keep it together with
      the other xattr cleanups if possible, though.  Could you please review?
      
      Thanks,

      ubifs: Switch to generic xattr handlers · 2b88fc21
      Andreas Gruenbacher authored
      Ubifs internally uses special inodes for storing xattrs. Those inodes
      had NULL {get,set,remove}xattr inode operations before this change, so
      xattr operations on them would fail. The super block's s_xattr field
      would also apply to those special inodes. However, the inodes are not
      visible outside of ubifs, and so no xattr operations will ever be
      carried out on them anyway.
