      Pull arm64 updates from Will Deacon:
       "The big highlight is support for the Scalable Vector Extension (SVE)
        which required extensive ABI work to ensure we don't break existing
        applications by blowing away their signal stack with the rather large
        new vector context (<= 2 kbit per vector register). There's further
        work to be done optimising things like exception return, but the ABI
        is solid now.
      
        Much of the line count comes from some new PMU drivers we have, but
        they're pretty self-contained and I suspect we'll have more of them in
        future.
      
        Plenty of acronym soup here:
      
         - initial support for the Scalable Vector Extension (SVE)
      
         - improved handling for SError interrupts (required to handle RAS
           events)
      
         - enable GCC support for 128-bit integer types
      
         - remove kernel text addresses from backtraces and register dumps
      
         - use of WFE to implement long delay()s

      Pull RISC-V architecture support from Palmer Dabbelt:
       "This contains the core RISC-V Linux port, which has been through nine
        rounds of review on various mailing lists. The port is not complete:
        there's some cleanup patches moving through the review process, a
        whole bunch of drivers that need some work, and a lot of feature
        additions that will be needed.
      
        The patches contained in this tag have been through nine rounds of
        review on the various mailing lists. I have some outstanding cleanup
        patches, but since there's been so much review on these patches I
        thought it would be best to submit them as-is and then submit explicit
        cleanup patches so everyone can review them. This first patch set is
        big enough that it's a bit of a pain to constantly rewrite, and it's
        caused a few headaches with various contributors.
      
        The port is definately a work in progress. While what's there builds
        and boots with 4.14, it's a bit hard to actually see anything happen
        because there are no device drivers yet. I maintain a staging branch
        that contains all the device drivers and cleanup that actually works,
        but those patches won't all be ready for a while. I'd like to get what
        we currently have into your tree so everyone can start working from a
        single base -- of particular importance is allowing the glibc
        upstreaming process to proceed so we can sort out any possibly
        lingering user-visible ABI problems we might have.
      
        Copied below is the ChangeLog that contains the history of this patch
        set:
      
         (v9) As per suggestions on our v8 patch set, I've split the core
              architecture code out from our drivers and would like to submit
              this patch set to be included into linux-next, with the goal
              being to be merged in during the next merge window. This patch
              set is based on 4.14-rc2, but if it's better to have it based on
              something else then I can change it around.
      
              This patch set contains just the core arch code for RISC-V, so
              while it builds an nominally boots, you can't print or take an
              interrupt so it's not that useful. If you're looking to actually
              boot a system it would probably be better to use the full patch
              set listed below.
      
              We've collected a handful of tags from reviewers, and the
              remainder of the patch set only got minimal feedback last time.
              Here's what changed:
      
               - We now use the device tree to initialize the timer driver so
                 it's less tighly coupled with the arch port.
      
               - I cleaned up the defconfigs -- there's actually now just one,
                 and it's empty. For now I think we're OK with what the kernel
                 sets as defaults, but I anticipate we'll begin to expand this
                 as people start to use the port more.
      
               - The VDSO symbols version is sane.
      
               - We WFI while spinning in the boot loop.
      
               - A handful of comments have been added.
      
              While there are still a handful of FIXMEs in this patch set,
              we've started to get enough interest from various users and
              contributors that maintaining an out of tree patch set is
              starting to become a big burden. Hopefully the patches are good
              enough to merge now, which will at least get everyone working in
              a more reasonable manner as we clean up the remaining issues.
      
         (v8) I know it may not be the ideal time to submit a patch set right
              now, as it's the middle of the merge window, but things have
              calmed down quite a bit in the last month so I thought it would
              be good to get everyone on the same page. There's been a handful
              of changes since the last patch set, but most of them are fairly
              minor:
      
               - We changed PAGE_OFFSET to allowing mapping more physical
                 memory on 64-bit systems. This is user configurable, as it
                 triggers a different code model that generates slightly less
                 efficient code.
      
               - The device tree binding documentation is back, I'd managed to
                 lose it at some point.
      
               - We now pass the atomic64 test suite
      
               - The SBI timer driver has been refactored.
      
         (v7) It's been a while since my last patch set, but the changes han
              been fairly minimal:
      
               - The PCI cleanup patches have been dropped, we'll do them as a
                 separate patch set later.
      
               - We've the Kconfig entries from CONFIG_ISA_* to
                 CONFIG_RISCV_ISA_*, to make grep easier.
      
               - There have been a handful of memory model related tweaks in
                 I/O land, particularly relating the PCI and the upcoming
                 platform specification. There are significant comments in the
                 relevant files. This is still a WIP, but I think we're close
                 to getting as good as we're going to get until we end up with
                 some more specifications.
      
         (v6) As it's been only a day since the v5 patch set, the changes are
              pretty minimal:
      
               - The patch set is now based on linux-next/master, which I
                 believe is a better base now that we're getting closer to
                 upstream.
      
               - EARLY_PRINTK is no longer an option. Since the SBI console is
                 reasonable, there's no penalty to enabling it (and thus no
                 benefit to disabling it).
      
               - The mmap syscalls were refactored a bit.
      
         (v5) Things have really started to calm down, so this is fairly
              similar to the v4 patch set. The most interesting changes
              include:
      
               - We've moved back to a single patch set.
      
               - SMP support has been fixed, I was accidentally running on a
                 non-SMP configuration. There were various mistakes all over
                 the tree as a result of this.
      
               - The cmpxchg syscalls have been removed, as they were deemed a
                 bad idea. As a result, RISC-V Linux systems mandate the A
                 extension. The corresponding Kconfig entry to enable builds
                 on non-A systems has been removed.
      
               - A few more atomic fixes: mostly fence changes, but those
                 resulted in a handful of additional macros that were no
                 longer necessary.
      
               - riscv_early_sie has been removed.
      
         (v4) There have only been a few changes since the v3 patch set:
      
               - The cmpxchg64 syscall is no longer enabled on 32-bit systems.
                 It's not possible to provide this on SMP systems, and it's
                 not necessary as glibc knows not to call it.
      
               - We provide a ELF_HWCAP so users can determine the ISA of the
                 machine the kernel is running on.
      
               - The multi-line comments are in a better form.
      
               - There were a handful of headers that could be replaced with
                 the asm-generic versions, and a few unnecessary definitions.
      
               - We no longer use printk, but instead use pr_*.
      
               - A few Kconfig and defconfig entries have been cleaned up.
      
         (v3) A highlight of the changes since the v2 patch set includes:
      
               - We've split out all our drivers into separate patch sets,
                 which I've already sent out to the relevant maintainers. I
                 haven't included those patches in this patch set, but some of
                 them are necessary to build our port.
      
               - The patch set is now split up differently: rather than being
                 split per directory it is split per topic. Hopefully this
                 will make it easier to review the port on the mailing list.
                 The split is a bit rough, so you probably still want to look
                 at the patch set as a whole.
      
               - atomic.h has been completely rewritten and is hopefully now
                 correct. I've attempted to sanitize the various other memory
                 model related code as well, and I think it should all be sane
                 now aside from a handful of FIXMEs commented in the code.
      
               - We've changed the cmpexchg syscall to always exist and to not
                 be multiplexed. There is also a VDSO entry for compare and
                 exchange, which allows kernels with the A extension to
                 execute user code without the A extension reasonably fast.
      
               - Our user-visible register state now contains enough space for
                 the Q extension for 128-bit floating point, as well as a few
                 words to allow extensibility to future ISA extensions like
                 the eventual V extension for vectors.
      
               - A handful of driver cleanups, but these have been split into
                 separate patch sets now so I won't duplicate them here.
      
         (v2) A highlight of the changes since the v1 patch set includes:
      
               - We've split out our drivers into the right places, which
                 means now there's a lot more patches. I'll be submitting
                 these patches to various subsystem maintainers and including
                 them in any future RISC-V patch sets until they've been
                 merged.
      
               - The SBI console driver has been completely rewritten to use
                 the HVC helpers and is now significantly smaller.
      
               - We've begun to use weaker barriers as opposed to just the big
                 "fence". There's still some work to do here, specifically:
                  - We need fences in the relaxed MMIO functions.
                  - The non-relaxed MMIO functions are missing R/W bits on their fences.
                  - Many AMOs need the aq and rl bits set.
      
               - We now have thread_info in task_struct. As a result, sscratch
                 now contains TP instead of SP. This was necessary because
                 thread_info is no longer on the stack.
      
               - A few shared routines have been added that we use instead of
                 creating another arch copy"

       "There are no big surprising changes in this cycle, yet not too boring,
        either. The biggest change from diffstat POV is the removal of the
        legacy OSS driver codes that have been already disabled for a long
        time. This will bring a few trivial merge conflicts.
      
        As new features in ASoC side, there are two things: a new AC97 bus
        implementation and AMD Stony platform support. Both include the
        relevant changes shared with other subsystems, e.g. AC97 MFD changes
        and DRM AMD changes.
      
        Some other highlighted topics are:
      
         - A bunch of USB-audio drivers got the hardening against the
           malicious device accesses with a new helper code for endpoint
           sanity check

        all have proper acks, caused no merge conflicts in linux-next where
        they have been for a while. They are namely:
      
         - to-gpiod conversion of the i2c-gpio driver and its users (touching
           arch/* and drivers/mfd/*)

           (touching drivers/power/*)
      
        Other notable changes:
      
         - i2c_boardinfo can now carry a dev_name to be used when the device
           is created. This is because some devices in ACPI world need fixed
           names to find the regulators.
      
         - the designware driver got a long discussed overhaul of its PM
           handling. img-scb and davinci got PM support, too.
      
         - at24 driver has way better OF support. And it has a new maintainer.

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.15 kernel cycle:
      
        Core:
      
         - 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
           hammer.
      
         - 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
           disastrous.
      
         - 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
           infrastructure.
      
        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"

      Pull core block layer updates from Jens Axboe:
       "This is the main pull request for block storage for 4.15-rc1.
      
        Nothing out of the ordinary in here, and no API changes or anything
        like that. Just various new features for drivers, core changes, etc.
        In particular, this pull request contains:
      
         - A patch series from Bart, closing the whole on blk/scsi-mq queue
           quescing.
      
         - A series from Christoph, building towards hidden gendisks (for
           multipath) and ability to move bio chains around.
      
         - NVMe
              - Support for native multipath for NVMe (Christoph).
              - Userspace notifications for AENs (Keith).
              - Command side-effects support (Keith).
              - SGL support (Chaitanya Kulkarni)
              - FC fixes and improvements (James Smart)
              - Lots of fixes and tweaks (Various)
      
         - bcache
              - New maintainer (Michael Lyle)
              - Writeback control improvements (Michael)
              - Various fixes (Coly, Elena, Eric, Liang, et al)
      
         - 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
           (me).
      
         - Fix for missing wakeup on writeback timer adjustments (Yafang
           Shao).
      
         - Fix laptop mode on blk-mq (me).
      
         - {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).
      
         - Loop cgroup support (Shaohua).
      
         - Lots of minor fixes from lots of different folks, both for core and
           driver code"

        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
           gfs2_block_map.
      
         - 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
           424.
      
         - 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"

      Pull btrfs updates from David Sterba:
       "There are some new user features and the usual load of invisible
        enhancements or cleanups.
      
        New features:
      
         - extend mount options to specify zlib compression level, -o
           compress=zlib:9
      
         - 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
           deduplication tools
      
         - populate compression heuristics logic, do data sampling and try to
           guess compressibility by: looking for repeated patterns, counting
           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
      
         - make delalloc reservations per-inode, simplify the code and make
           the logic more straightforward
      
         - extensive cleanup of delayed refs code
      
        Notable fixes:
      
         - fix send ioctl on 32bit with 64bit kernel"

      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
           fragmented.
      
         - 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
           verified.
      
         - 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"
