      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.15 kernel cycle:
         - Fix the semantics of raw GPIO to actually be raw. No inversion
           semantics as before, but also no open draining, and allow the raw
           operations to affect lines used for interrupts as the caller
           supposedly knows what they are doing if they are getting the big
         - Rewrote the __inner_function() notation calls to names that make
           more sense. I just find this kind of code disturbing.
         - Drop the .irq_base() field from the gpiochip since now all IRQs are
           mapped dynamically. This is nice.
         - Support for .get_multiple() in the core driver API. This allows us
           to read several GPIO lines with a single register read. This has
           high value for some usecases: it can be used to create
           oscilloscopes and signal analyzers and other things that rely on
           reading several lines at exactly the same instant. Also a generally
           nice optimization. This uses the new assign_bit() macro from the
           bitops lib that was ACKed by Andrew Morton and is implemented for
           two drivers, one of them being the generic MMIO driver so everyone
           using that will be able to benefit from this.
         - Do not allow requests of Open Drain and Open Source setting of a
           GPIO line simultaneously. If the hardware actually supports
           enabling both at the same time the electrical result would be
         - A new interrupt chip core helper. This will be helpful to deal with
           "banked" GPIOs, which means GPIO controllers with several logical
           blocks of GPIO inside them. This is several gpiochips per device in
           the device model, in contrast to the case when there is a 1-to-1
           relationship between a device and a gpiochip.
        New drivers:
         - Maxim MAX3191x industrial serializer, a very interesting piece of
           professional I/O hardware.
         - Uniphier GPIO driver. This is the GPIO block from the recent
           Socionext (ex Fujitsu and Panasonic) platform.
         - Tegra 186 driver. This is based on the new banked GPIO
        Other improvements:
         - Some documentation improvements.
         - Wakeup support for the DesignWare DWAPB GPIO controller.
         - Reset line support on the DesignWare DWAPB GPIO controller.
         - Several non-critical bug fixes and improvements for the Broadcom
           BRCMSTB driver.
         - Misc non-critical bug fixes like exotic errorpaths, removal of dead
           code etc.
         - Explicit comments on fall-through switch() statements"

         - lightnvm updates, mostly centered around the pblk interface
           (Javier, Hans, and Rakesh).
         - Removal of unused bio/bvec kmap atomic interfaces (me, Christoph)
         - Writeback series that fix the much discussed hundreds of millions
           of sync-all units. This goes all the way, as discussed previously

         - {mq,name} tupple lookup for IO schedulers, allowing us to have
           alias names. This means you can use 'deadline' on both !mq and on
           mq (where it's called mq-deadline). (me).
         - blktrace race fix, oopsing on sg load (me).
         - blk-mq optimizations (me).
         - Obscure waitqueue race fix for kyber (Omar).
         - NBD fixes (Josef).
         - Disable writeback throttling by default on bfq, like we do on cfq
           (Luca Miccio).
         - Series from Ming that enable us to treat flush requests on blk-mq
           like any other request. This is a really nice cleanup.
         - Series from Ming that improves merging on blk-mq with schedulers,
           getting us closer to flipping the switch on scsi-mq again.
         - BFQ updates (Paolo).
         - blk-mq atomic flags memory ordering fixes (Peter Z).

      Pull gfs2 updates from Bob Peterson:
       "We've got a total of 17 GFS2 patches for this merge window. The
        patches are basically in three categories: (1) patches related to
        broken xfstest cases, (2) patches related to improving iomap and start
        using it in GFS2, and (3) general typos and clarifications.
        Please note that one of the iomap patches extends beyond GFS2 and
        affects other file systems, but it was publically reviewed by a
        variety of file system people in the community.
        From Andreas Gruenbacher:
         - rename variable 'bsize' to 'factor' to clarify the logic related to
         - correctly set ctime in the setflags ioctl, which fixes broken
           xfstests test 277.
         - fix broken xfstest 258, due to an atime initialization problem.
         - fix broken xfstest 307, in which GFS2 was not setting ctime when
           setting acls.
         - switch general iomap code from blkno to disk offset for a variety
           of file systems.
         - add a new IOMAP_F_DATA_INLINE flag for iomap to indicate blocks
           that have data mixed with metadata.
         - implement SEEK_HOLE and SEEK_DATA via iomap in GFS2.
         - fix failing xfstest case 066, which was due to not properly syncing
           dirty inodes when changing extended attributes.
         - fix a minor typo in a comment.
         - partially fix xfstest 424, which involved GET_FLAGS and SET_FLAGS
           ioctl. This is also a cleanup and simplification of the translation
           of flags from fs flags to gfs2 flags.
         - add support for STATX_ATTR_ in statx, which fixed broken xfstest
         - fix for failing xfstest 093 which fixes a recursive glock problem
           with gfs2_xattr_get and _set
        From me:
         - make inode height info part of the 'metapath' data structure to
           facilitate using iomap in GFS2.
         - start using iomap inside GFS2 and switch GFS2's block_map functions
           to use iomap under the covers.
         - switch GFS2's fiemap implementation from using block_map to using
           iomap under the covers.
         - fix journaled data pages not being properly synced to media when
           writing inodes. This was caught with xfstests.
         - fix another failing xfstest case in which switching a file from
           ordered_write to journaled data via set_flags caused a deadlock"

         - extend mount options to specify zlib compression level, -o
         - v2 of ioctl "extent to inode mapping", addressing a usecase where
           we want to retrieve more but inaccurate results and do the
           postprocessing in userspace, aiding defragmentation or

           unique byte values and distribution, calculating Shannon entropy;
           this will need more benchmarking and possibly fine tuning, but the
           base should be good enough
         - enable indexing for btrfs as lower filesystem in overlayfs
         - speedup page cache readahead during send on large files
        Internal enhancements:
         - more sanity checks of b-tree items when reading them from disk
         - more EINVAL/EUCLEAN fixups, missing BLK_STS_* conversion, other
           errno or error handling fixes
         - remove some homegrown IO-related logic, that's been obsoleted by
           core block layer changes (batching, plug/unplug, own counters)
         - add ref-verify, optional debugging feature to verify extent
           reference accounting
         - simplify code handling outstanding extents, make it more clear
           where and how the accounting is done

      Pull xfs updates from Darrick Wong:
       "xfs: great scads of new stuff for 4.15.
        This merge cycle, we're making some substantive changes to XFS. The
        in-core extent mappings have been refactored to use proper iterators
        and a btree to handle heavily fragmented files without needing
        high-order memory allocations; some important log recovery bug fixes;
        and the first part of the online fsck functionality.
        (The online fsck feature is disabled by default and more pieces of it
        will be coming in future release cycles.)
        This giant pile of patches has been run through a full xfstests run
        over the weekend and through a quick xfstests run against this
        morning's master, with no major failures reported.
        New in this version:
         - Refactor the incore extent map manipulations to use a cursor
           instead of directly modifying extent data.
         - Refactor the incore extent map cursor to use an in-memory btree
           instead of a single high-order allocation. This eliminates a major
           source of complaints about insufficient memory when opening a
           heavily fragmented file into a system whose memory is also heavily
         - Fix a longstanding bug where deleting a file with a complex
           extended attribute btree incorrectly handled memory pointers, which
           could lead to memory corruption.
         - Improve metadata validation to eliminate crashing problems found
           while fuzzing xfs.
         - Move the error injection tag definitions into libxfs to be shared
           with userspace components.
         - Fix some log recovery bugs where we'd underflow log block position
           vector and incorrectly fail log recovery.
         - Drain the buffer lru after log recovery to force recovered buffers
           back through the verifiers after mount. On a v4 filesystem the log
           never attaches verifiers during log replay (v5 does), so we could
           end up with buffers marked verified but without having ever been
         - Fix various other bugs.
         - Introduce the first part of a new online fsck tool. The new fsck
           tool will be able to iterate every piece of metadata in the
           filesystem to look for obvious errors and corruptions. In the next
           release cycle the checking will be extended to cross-reference with
           the other fs metadata, so this feature should only be used by the
           developers in the mean time"

      Pull USB/PHY updates from Greg KH:
       "Here is the big set of USB and PHY driver updates for 4.15-rc1.
        There is the usual amount of gadget and xhci driver updates, along
        with phy and chipidea enhancements. There's also a lot of SPDX tags
        and license boilerplate cleanups as well, which provide some churn in
        the diffstat.
        Other major thing is the typec code that moved out of staging and into
        the "real" part of the drivers/usb/ tree, which was nice to see
        All of these have been in linux-next with no reported issues for a
