      Pull misc compat stuff updates from Al Viro:
       "This part is basically untangling various compat stuff. Compat
        syscalls moved to their native counterparts, getting rid of quite a
        bit of double-copying and/or set_fs() uses. A lot of field-by-field
        copyin/copyout killed off.
      
         - kernel/compat.c is much closer to containing just the
           copyin/copyout of compat structs. Not all compat syscalls are gone
           from it yet, but it's getting there.
      
         - ipc/compat_mq.c killed off completely.
      
         - block/compat_ioctl.c cleaned up; floppy compat ioctls moved to
           drivers/block/floppy.c where they belong. Yes, there are several
           drivers that implement some of the same ioctls. Some are m68k and
           one is 32bit-only pmac. drivers/block/floppy.c is the only one in
           that bunch that can be built on biarch"

      Pull tracing updates from Steven Rostedt:
       "The new features of this release:
      
         - Added TRACE_DEFINE_SIZEOF() which allows trace events that use
           sizeof() it the TP_printk() to be converted to the actual size such
           that trace-cmd and perf can parse them correctly.
      
         - Some rework of the TRACE_DEFINE_ENUM() such that the above
           TRACE_DEFINE_SIZEOF() could reuse the same code.
      
         - Recording of tgid (Thread Group ID). This is similar to how task
           COMMs are recorded (cached at sched_switch), where it is in a table
           and used on output of the trace and trace_pipe files.
      
         - Have ":mod:<module>" be cached when written into set_ftrace_filter.
           Then the functions of the module will be traced at module load.
      
         - Some random clean ups and small fixes"

      Pull dma-mapping infrastructure from Christoph Hellwig:
       "This is the first pull request for the new dma-mapping subsystem
      
        In this new subsystem we'll try to properly maintain all the generic
        code related to dma-mapping, and will further consolidate arch code
        into common helpers.
      
        This pull request contains:
      
         - removal of the DMA_ERROR_CODE macro, replacing it with calls to
           ->mapping_error so that the dma_map_ops instances are more self
           contained and can be shared across architectures (me)
      
         - removal of the ->set_dma_mask method, which duplicates the
           ->dma_capable one in terms of functionality, but requires more
           duplicate code.
      
         - various updates for the coherent dma pool and related arm code
           (Vladimir)

       "This includes two bugs against the newly added opa vnic that were
        found by turning on the debug kernel options:
      
         - sleeping while holding a lock, so a one line fix where they
           switched it from GFP_KERNEL allocation to a GFP_ATOMIC allocation
      
         - a case where they had an isolated caller of their code that could
           call them in an atomic context so they had to switch their use of a
           mutex to a spinlock to be safe, so this was considerably more lines
           of diff because all uses of that lock had to be switched
      
        In addition, the bug that was discussed with you already about an out
        of bounds array access in ib_uverbs_modify_qp and ib_uverbs_create_ah
        and is only seven lines of diff.
      
        And finally, one fix to an earlier fix in the -rc cycle that broke
        hfi1 and qib in regards to IPoIB (this one is, unfortunately, larger
        than I would like for a -rc7 submission, but fixing the problem
        required that we not treat all devices as though they had allocated a
        netdev universally because it isn't true, and it took 70 lines of diff
        to resolve the issue, but the final patch has been vetted by Intel and
        Mellanox and they've both given their approval to the fix).
      
        Summary:
      
         - Two fixes for OPA found by debug kernel
         - Fix for user supplied input causing kernel problems
         - Fix for the IPoIB fixes submitted around -rc4"
      
      [ Doug sent this having not noticed the 4.12 release, so I guess I'll be
        getting another rdma pull request with the actuakl merge window
        updates and not just fixes.
      
        Oh well - it would have been nice if this small update had been the
        merge window one.     - Linus ]

      Pull pin control updates from Linus Walleij:
       "This is the big bulk of pin control changes for the v4.13 series:
      
        Core:
         - The documentation is moved over to RST.
         - We now have agreed bindings for enabling input and output buffers
           without actually enabling input and/or output on a pin. We are
           chiseling out some details of pin control electronics.
      
        New drivers:
         - ZTE ZX
         - Renesas RZA1
         - MIPS Ingenic JZ47xx: also switch over existing drivers in the tree
           to use this pin controller and consolidate earlier spread out code.
         - Microschip MCP23S08: this driver is migrated from the GPIO
           subsystem and totally rewritten to use proper pin control. All
           users are switched over.
      
        New subdrivers:
         - Renesas R8A7743 and R8A7745.
         - Allwinner Sunxi A83T R_PIO.
         - Marvell MVEBU Armada CP110 and AP806.
         - Intel Cannon Lake PCH.
         - Qualcomm IPQ8074.
      
        Notable improvements:
         - IRQ support on the Marvell MVEBU Armada 37xx.
         - Meson driver supports HDMI CEC, AO, I2S, SPDIF and PWM.
         - Rockchip driver now supports iomux-route switching for RK3228,
           RK3328 and RK3399.
         - Rockchip A10 and A20 are merged into a single driver.
         - STM32 has improved GPIO support.
         - Samsung Exynos drivers are split per ARMv7 and ARMv8.
         - Marvell MVEBU is converted to use regmap for register access.
      
        Maintenance:
         - Several Renesas SH-PFC refactorings and updates.
         - Serious code size cut for Mediatek MT7623.
         - Misc janitorial and MAINTAINERS fixes"

        about PCM. Also the support of of-graph card and the new DAPM widget
        for DSP are noteworthy changes in ASoC core. And there're lots of
        small changes splat over the tree, as you can see in diffstat.
      
        Below are a few highlights:
      
        ALSA core:
         - Removal of set_fs() hackery from PCM core stuff, and the code
           reorganization / optimization thereafter
         - Improved support of PCM ack ops, and a new ABI for improved
           control/status mmap handling
         - Lots of constifications in various codes
      
        ASoC core:
         - The support of of-graph card, which may work as a better generic
           device for a replacement of simple-card
         - New widget types intended mainly for use with DSPs
      
        ASoC drivers:
         - New drivers for Allwinner V3s SoCs
         - Ensonic ES8316 codec support
         - More Intel SKL and KBL works
         - More device support for Intel SST Atom (mostly for cheap tablets
           and 2-in-1 devices)
         - Support for Rockchip PDM controllers
         - Support for STM32 I2S and S/PDIF controllers
         - Support for ZTE AUD96P22 codecs
      
        HD-audio:
         - Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks
           for HP and Dell machines
         - A few more fixes for i915 component binding"

      Pull mnt namespace updates from Eric Biederman:
       "A big break-through came during this development cycle as a way was
        found to maintain the existing umount -l semantics while allowing for
        optimizations that improve the performance. That is represented by the
        first change in this series moving the reparenting of mounts into
        their own pass. This has allowed addressing the horrific performance
        of umount -l on a carefully crafted tree of mounts with locks held
        (0.06s vs 60s in my testing). What allowed this was not changing where
        umounts propagate to while propgating umounts.
      
        The next change fixes the case where the order of the mount whose
        umount are being progated visits a tree where the mounts are stacked
        upon each other in another order. This is weird but not hard to
        implement.
      
        The final change takes advantage of the unchanging mount propgation
        tree to skip parts of the mount propgation tree that have already been
        visited. Yielding a very nice speed up in the worst case.
      
        There remains one outstanding question about the semantics of umount -l
        that I am still discussiong with Ram Pai. In practice that area of the
        semantics was changed by 1064f874 ("mnt: Tuck mounts under others
        instead of creating shadow/side mounts.") and no regressions have been
        reported. Still I intend to finish talking that out with him to ensure
        there is not something a more intense use of mount propagation in the
        future will not cause to become significant"

      Pull GFS2 updates from Bob Peterson:
       "We've got eight GFS2 patches for this merge window:
      
         - Andreas Gruenbacher has four patches related to cleaning up the
           GFS2 inode evict process. This is about half of his patches
           designed to fix a long-standing GFS2 hang related to the inode
           shrinker: Shrinker calls gfs2 evict, evict calls DLM, DLM requires
           memory and blocks on the shrinker.
      
           These four patches have been well tested. His second set of patches
           are still being tested, so I plan to hold them until the next merge
           window, after we have more weeks of testing. The first patch
           eliminates the flush_delayed_work, which can block.
      
         - Andreas's second patch protects setting of gl_object for rgrps with
           a spin_lock to prevent proven races.
      
         - His third patch introduces a centralized mechanism for queueing
           glock work with better reference counting, to prevent more races.
      
          -His fourth patch retains a reference to inode glocks when an error
           occurs while creating an inode. This keeps the subsequent evict
           from needing to reacquire the glock, which might call into DLM and
           block in low memory conditions.
      
         - Arvind Yadav has a patch to add const to attribute_group
           structures.
      
         - I have a patch to detect directory entry inconsistencies and
           withdraw the file system if any are found. Better that than silent
           corruption.
      
         - I have a patch to remove a vestigial variable from glock
           structures, saving some slab space.

      IB/core, opa_vnic, hfi1, mlx5: Properly free rdma_netdev · 8e959601
      Niranjana Vishwanathapura authored
      IPOIB is calling free_rdma_netdev even though alloc_rdma_netdev has
      returned -EOPNOTSUPP.
      Move free_rdma_netdev from ib_device structure to rdma_netdev structure
      thus ensuring proper cleanup function is called for the rdma net device.
      
      Fix the following trace:

      dm zoned: fix overflow when converting zone ID to sectors · 3908c983
      Damien Le Moal authored
      A zone ID is a 32 bits unsigned int which can overflow when doing the
      bit shifts in dmz_start_sect().  With a 256 MB zone size drive, the
      overflow happens for a zone ID >= 8192.
      
      Fix this by casting the zone ID to a sector_t before doing the bit
      shift.  While at it, similarly fix dmz_start_block().

      Cavium CNN55XX: fix broken default Kconfig entry · b4b8cbf6
      Linus Torvalds authored
      Every developer always thinks that _their_ code is so special and
      magical that it should be enabled by default.
      
      And most of them are completely and utterly wrong.  That's definitely
      the case when you write a specialty driver for a very unsual "security
      processor". It does *not* get to mark itself as "default m".
      
      If you solve world hunger, and make a driver that cures people of
      cancer, by all means enable it by default.  But afaik, the Cavium
      CNN55XX does neither.
