      Pull tracking updates from Steven Rostedt:
       "Most of the changes are clean ups and small fixes.  Some of them have
        stable tags to them.  I searched through my INBOX just as the merge
        window opened and found lots of patches to pull.  I ran them through
        all my tests and they were in linux-next for a few days.
      
        Features added this release:
        ----------------------------
      
         - Module globbing.  You can now filter function tracing to several
           modules.  # echo '*:mod:*snd*' > set_ftrace_filter (Dmitry Safonov)
      
         - Tracer specific options are now visible even when the tracer is not
           active.  It was rather annoying that you can only see and modify
           tracer options after enabling the tracer.  Now they are in the
           options/ directory even when the tracer is not active.  Although
           they are still only visible when the tracer is active in the
           trace_options file.
      
         - Trace options are now per instance (although some of the tracer
           specific options are global)
      
         - New tracefs file: set_event_pid.  If any pid is added to this file,
           then all events in the instance will filter out events that are not
           part of this pid.  sched_switch and sched_wakeup events handle next
           and the wakee pids"
      
      * tag 'trace-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (68 commits)
        tracefs: Fix refcount imbalance in start_creating()
        tracing: Put back comma for empty fields in boot string parsing
        tracing: Apply tracer specific options from kernel command line.
        tracing: Add some documentation about set_event_pid
        ring_buffer: Remove unneeded smp_wmb() before wakeup of reader benchmark
        tracing: Allow dumping traces without tracking trace started cpus

      HID: logitech: Add support for G29 · 29fae1c8
      Simon Wood authored
      At present the G29 is mis-identified as a DFGT, this patch ensures
      that the wheel is correctly detected and allows setting the LEDs and
      turning range via the '/sys' interface.
      
      This wheel can also emulate other types of Logitech wheels.

      Sebastian Reichel authored
      This reverts commit af19161a,
      which breaks the omap3 device tree build due to a wrong reference.
      
      I accidently queued this change via the power supply subsystem while
      telling Marek at the same time, that it should go through Tony.
      Following that I did miss Stephen's messages about the build failure in
      linux-next and since he switched to merging an older snapshot nobody
      else noticed the problem in my tree. I didn't notice myself, since I
      did not build any device tree files assuming none have changed by me.

       "A fairly large (by DT standards) pull request this time with the

         - DT binding doc consolidation moving similar bindings to common
           locations.  The majority of these are display related which were
           scattered in video/, fb/, drm/, gpu/, and panel/ directories.
      
         - Add new config option, CONFIG_OF_ALL_DTBS, to enable building all
           dtbs in the tree for most arches with dts files (except powerpc for
           now).

           bindings.
      
         - DT binding for PXA LCD controller.
      
         - Allow ignoring failed PCI resource translations in order to ignore
           64-bit addresses on non-LPAE 32-bit kernels.
      
         - Support setting the NUMA node from DT instead of only from parent

      Pull MTD updates from Brian Norris:
       "Core:
      
         - WARN (in some cases) when a struct mtd_info is registered multiple
           times; in the past this was "supported", but it's still error prone
           for future development.  There's only one ugly case of this left in
           the tree (that we're aware of) and the owners are aware of the
           problems there.
      
         - fix potential deadlock in the blkdev removal path NOTE: the
           (potential) deadlock was introduced in a for-stable patch.  This
           one is also marked for -stable.
      
         - ioctl(BLKPG) compat_ioctl support; resolves issues with 32-bit user
           space vs 64-bit kernel space
      
         - Set MTD parent device correctly throughout the tree, so the tree
           structure appears correctly in sysfs; many drivers were missing
           this (soft) requirement
      
         - Move device tree partitions (ofpart) into a dedicated 'partitions'
           subnode; this helps to disambiguate whether a node is a partition
           or some other auxiliary data
      
         - Improve error handling for partitioning failures
      
        NAND:
      
         - General: Increase timeout period, for corner-case systems with
           less-than-accurate jiffies
      
         - Fix OF-based autoloading of several NAND drivers when built as
           modules
      
         - pxa3xx_nand:
            - Rework timing configuration to be more dynamic
            - Refactor PM support
      
         - brcmnand: prepare for NorthStar 2 support (ARM64, 16-bit NAND
           chips)
      
         - sunxi_nand: refactoring and a few bug fixes
      
         - vf610: new NAND driver
      
         - FSMC: add SW BCH support; support common NAND DT bindings
      
         - lpc32xx_slc: refactor and improve timing calculations logic
      
         - denali: support for rev 5.1
      
        SPI NOR:
      
         - Layering improvements
      
         - Added Winbond lock/unlock support
      
         - Added mtd_is_locked() (i.e., ioctl(MEMISLOCKED)) support
      
         - Increase full-chip-erase timeout linearly with flash size
      
         - fsl-quadspi: fix compile for non-ARM architectures
      
         - New flash support"

      Pull sound updates from Takashi Iwai:
       "Here is the first batch of updates for sound system on 4.4-rc1.
      
        Again at this time, the update looks fairly calm; no big changes in
        either ALSA core or ASoC infrastructures, rather all small cleanups,
        in addition to the new stuff as usual.
      
        The biggest changes are about Firewire sound devices.  It gained lots
        of new device support, and MIDI functionality.  Also there are updates
        for a few still working-in-progress stuff (topology API and ASoC
        skylake), too.  But overall, this update should give no big surprise.
      
        Some highlights are below:
      
        Core:
         - A few more Kconfig items for tinification; it's marked as EXPERT,
           so normal user should't be bothered :)
         - Refactoring with a new PCM hw_constraint helper
         - Removal of unused transfer_ack_{begin,end} PCM callbacks
      
        Firewire:
         - Restructuring of code subtree, lots of refactoring
         - Support AMDTP variants
         - New driver for Digidesign 002/003 family
         - Adds support for TASCAM FireOne to ALSA OXFW driver
         - Add MIDI support to TASCAM and Digi00x devices
      
        HD-Audio:
         - Automated modalias generation for codec drivers, finally
         - Improvement on heuristics for setting mixer name
         - A few fixes for longstanding bugs on Creative CA0132 cards
         - Addition of audio rate callback with i915 communication
         - Fix suspend issue on recent Dell XPS
         - Intel Lewisburg controller support
      
        ASoC:
         - Updates to the topology userspace interface
         - Big updates to the Renesas support (rcar)
         - More updates for supporting Intel Sky Lake systems
         - New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10,
           Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825, Rockchip
           S/PDIF, and Atmel class D amplifier
      
        USB-Audio:
         - A fix for newer Roland MIDI devices
         - Quirks and workarounds for Zoom R16/24 device
      
        Misc:
         - A few fixes for some old Cirrus CS46xx PCI sound boards
         - Yet another fixes for some old ESS Maestro3 PCI sound boards"

      mfd: avoid newly introduced compiler warning · 4dcee4d8
      Linus Torvalds authored
      Commit b158b69a ("mfd: rtsx: Simplify function return logic")
      removed the use of the 'err' variable, but left the variable itself
      around, resulting in gcc quite reasonably warning:
      
          drivers/mfd/rtsx_pcr.c: In function ‘rtsx_pci_set_pull_ctl’:
          drivers/mfd/rtsx_pcr.c:565:6: warning: unused variable ‘err’ [-Wunused-variable]
            int err;
                ^
      
      Get rid of the unused variable, and avoid the new warning.

      mtd: don't WARN about overloaded users of mtd->reboot_notifier.notifier_call · f8479dd6
      Brian Norris authored
      There are multiple types of users of mtd->reboot_notifier.notifier_call:
      
      (1) A while back, the cfi_cmdset_000{1,2} chip drivers implemented a
      reboot notifier to (on a best effort basis) attempt to reset their flash
      chips before rebooting.
      
      (2) More recently, we implemented a common _reboot() hook so that MTD
      drivers (particularly, NAND flash) could better halt I/O operations
      without having to reimplement the same notifier boilerplate.
      
      Currently, the WARN_ONCE() condition here was written to handle (2), but
      at the same time it mis-diagnosed case (1) as an already-registered MTD.
      Let's fix this by having the WARN_ONCE() condition better imitate the
      condition that immediately follows it. (Wow, I don't know how I missed
      that one.)
      
      (Side note: Unfortunately, we can't yet combine the reboot notifier code
      for (1) and (2) with a patch like [1], because some users of (1) also
      use mtdconcat, and so the mtd_info struct from cfi_cmdset_000{1,2} won't
      actually get registered with mtdcore, and therefore their reboot
      notifier won't get registered.)

      x86: don't make DEBUG_WX default to 'y' even with DEBUG_RODATA · 54727e6e
      Linus Torvalds authored
      It turns out that we still have issues with the EFI memory map that ends
      up polluting our kernel page tables with writable executable pages.
      
      That will get sorted out, but in the meantime let's not make the scary
      complaint about them be on by default.  The code is useful for
      developers, but not ready for end user testing yet.

      bcache: Really show state of work pending bit · 8d090f47
      Petr Mladek authored
      WORK_STRUCT_PENDING is a mask for testing the pending bit.
      test_bit() expects the number of the bit and we need to
      use WORK_STRUCT_PENDING_BIT there.
      
      Also work_data_bits() is defined in workqueues.h now.
      
      I have noticed this just by chance when looking how
      WORK_STRUCT_PENDING_BIT is used. The change is compile
      tested.

      With !CONFIG_DEBUG_SET_MODULE_RONX, module text and rodata pages are
      writable, and the debug_align() macro allows the module struct to share
      a page with executable text.  When klp_write_module_reloc() calls
      set_memory_ro() on the page, it effectively turns the module struct into
      a read-only structure, resulting in a page fault when load_module() does
      "mod->state = MODULE_STATE_LIVE".
