      Pull security system updates from James Morris:
      
       - incorporate new socketpair() hook into LSM and wire up the SELinux
         and Smack modules. From David Herrmann:
      
           "The idea is to allow SO_PEERSEC to be called on AF_UNIX sockets
            created via socketpair(2), and return the same information as if
            you emulated socketpair(2) via a temporary listener socket.
      
            Right now SO_PEERSEC will return the unlabeled credentials for a
            socketpair, rather than the actual credentials of the creating
            process."
      
       - remove the unused security_settime LSM hook (Sargun Dhillon).
      
       - remove some stack allocated arrays from the keys code (Tycho
         Andersen)
      
      * 'next-general' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security:
        dh key: get rid of stack allocated array for zeroes

         and handled by another process.

      Pull IPMI updates from Corey Minyard:
       "It's been a busy release for the IPMI driver. Some notable changes:
      
         - A user was running into timeout issues doing maintenance commands
           over the IPMB network behind an IPMI controller.
      
           Extend the maintenance mode concept to messages over IPMB and allow
           the timeouts to be tuned.
      
         - Lots of cleanup, style fixing, some bugfixes, and such.
      
         - At least one user was having trouble with the way the IPMI driver
           would lock the i2c driver module it used.
      
           The IPMI driver was not designed for hotplug. However, hotplug is a
           reality now, so the IPMI driver was modified to support hotplug.
      
         - The proc interface code is now completely removed. Long live sysfs!"

      Pull Kselftest update from Shuah Khan:
      
       - Work to restructure timers test suite to move PIE out of rtctest from
         Alexandre Belloni.
      
       - Several minor spelling and bug fixes.
      
       - New cgroup tests from Roman Gushchin and Mike Rapoport.
      
       - Kselftest framework changes to handle and report skipped tests
         correctly.
      
         Prior to these changes, framework treated all non-zero return codes
         from tests as failures. When tests are skipped with non-zero return
         code, due to unmet dependencies and/or unsupported configuration,
         reporting them as failed lead to false negatives on the tests that
         couldn't be run.
      
       - Fixes to test Makefiles to remove unnecessary RUN_TESTS and
         EMIT_TESTS overrides and use common defines from lib.mk.
      
       - Fixes to several tests to return correct Kselftest skip code.

      Pull Kconfig updates from Masahiro Yamada:
       "Kconfig now supports new functionality to perform textual
        substitution. It has been a while since Linus suggested to move
        compiler option tests from makefiles to Kconfig. Finally, here it is.
      
        The implementation has been generalized into a Make-like macro
        language.
      
        Some built-in functions such as 'shell' are provided. Variables and
        user-defined functions are also supported so that 'cc-option',
        'ld-option', etc. are implemented as macros.
      
        Summary:
      
         - refactor package checks for building {m,n,q,g}conf
      
         - remove unused/unmaintained localization support
      
         - remove Kbuild cache
      
         - drop CONFIG_CROSS_COMPILE support
      
         - replace 'option env=' with direct variable expansion
      
         - add built-in functions such as 'shell'
      
         - support variables and user-defined functions
      
         - add helper macros as as 'cc-option'
      
         - add unit tests and a document of the new macro language
      
         - add 'testconfig' to help
      
         - fix warnings from GCC 8.1"

      Pull cgroup updates from Tejun Heo:
      
       - For cpustat, cgroup has a percpu hierarchical stat mechanism which
         propagates up the hierarchy lazily.
      
         This contains commits to factor out and generalize the mechanism so
         that it can be used for other cgroup stats too.
      
         The original intention was to update memcg stats to use it but memcg
         went for a different approach, so still the only user is cpustat. The
         factoring out and generalization still make sense and it's likely
         that this can be used for other purposes in the future.
      
       - cgroup uses kernfs_notify() (which uses fsnotify()) to inform user
         space of certain events. A rate limiting mechanism is added.
      
       - Other misc changes.

      Pull libata updates from Tejun Heo:
      
       - libata has always been limiting the maximum queue depth to 31, with
         one entry set aside mostly for historical reasons. This didn't use to
         make much difference but Jens found out that modern hard drives can
         actually perform measurably better with the extra one queue depth.
         Jens updated libata core so that it can make use of full 32 queue
         depth
      
       - Damien updated command retry logic in error handling so that it
         doesn't unnecessarily retry when upper layer (SCSI) is gonna handle
         them

       "New features this cycle include the ability to relabel mounted
        filesystems, support for fallocated swapfiles, and using FUA for pure
        data O_DSYNC directio writes. With this cycle we begin to integrate
        online filesystem repair and refactor the growfs code in preparation
        for eventual subvolume support, though the road ahead for both
        features is quite long.
      
        There are also numerous refactorings of the iomap code to remove
        unnecessary log overhead, to disentangle some of the quota code, and
        to prepare for buffer head removal in a future upstream kernel.
      
        Metadata validation continues to improve, both in the hot path
        veifiers and the online filesystem check code. I anticipate sending a
        second pull request in a few days with more metadata validation
        improvements.
      
        This series 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.
      
        Summary:
      
         - Strengthen inode number and structure validation when allocating
           inodes.
      
         - Reduce pointless buffer allocations during cache miss
      
         - Use FUA for pure data O_DSYNC directio writes
      
         - Various iomap refactorings
      
         - Strengthen quota metadata verification to avoid unfixable broken
           quota
      
         - Make AGFL block freeing a deferred operation to avoid blowing out
           transaction reservations when running complex operations
      
         - Get rid of the log item descriptors to reduce log overhead
      
         - Fix various reflink bugs where inodes were double-joined to
           transactions
      
         - Don't issue discards when trimming unwritten extents
      
         - Refactor incore dquot initialization and retrieval interfaces
      
         - Fix some locking problmes in the quota scrub code
      
         - Strengthen btree structure checks in scrub code
      
         - Rewrite swapfile activation to use iomap and support unwritten
           extents
      
         - Make scrub exit to userspace sooner when corruptions or
           cross-referencing problems are found
      
         - Make scrub invoke the data fork scrubber directly on metadata
           inodes
      
         - Don't do background reclamation of post-eof and cow blocks when the
           fs is suspended
      
         - Fix secondary superblock buffer lifespan hinting
      
         - Refactor growfs to use table-dispatched functions instead of long
           stringy functions
      
         - Move growfs code to libxfs
      
         - Implement online fs label getting and setting
      
         - Introduce online filesystem repair (in a very limited capacity)
      
         - Fix unit conversion problems in the realtime freemap iteration
           functions
      
         - Various refactorings and cleanups in preparation to remove buffer
           heads in a future release
      
         - Reimplement the old bmap call with iomap

         - Make it possible to use platform-specific suspend/resume hooks in
           the cpufreq-dt driver and make the Armada 37xx DVFS use that
           feature (Viresh Kumar, Miquel Raynal).

           events in the ACPI PM core during resume from suspend-to-idle if
           the EC has been put into the low-power mode (Rafael Wysocki).

      Commit 6870c016 ("scripts/faddr2line: show the code context")
      radically altered the output format of the faddr2line tool.  And while
      the new list output format might have merit it broke my vim usage and
      was hard to read.
      
      Make the new format optional; using a '--list' argument and attempt to
      make the output slightly easier to read by adding a little whitespace to
      separate the different files and explicitly mark the line in question.

      Merge tag 'asoc-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
      
      ASoC: Updates for v4.18
      
      This is a very big update, mainly due to a huge set of new drivers some
      of which are individually very large.  We also have a lot of fixes for
      the topology stuff, several of the users have stepped up and fixed some
      the serious issues there, and continued progress on the transition away
      from CODEC specific drivers to generic component drivers.
      
       - Many fixes for the topology code, including fixes for the half done
         v4 ABI compatibility from Guenter Roeck and other ABI fixes from
         Kirill Marinushkin.
       - Lots of cleanup for Intel platforms based on Realtek CODECs from Hans
         de Goode.
       - More followups on removing legacy CODEC things and transitioning to
         components from Morimoto-san.
       - Conversion of OMAP DMA to the new, more standard SDMA-PCM driver.
       - A series of fixes and updates to the rather elderly Cirrus Logic SoC
         drivers from Alexander Sverdlin.
       - Qualcomm DSP support from Srinivas Kandagatla.
       - New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek
         MT6351, MT6797 and MT7622, Qualcomm DSPs, Realtek RT1305, RT1306 and

      Kent Overstreet authored
      mempool_init()/bioset_init() require that the mempools/biosets be zeroed
      first; they probably should not _require_ this, but not allocating those
      structs with kzalloc is a fairly nonsensical thing to do (calling
      mempool_exit()/bioset_exit() on an uninitialized mempool/bioset is legal
      and safe, but only works if said memory was zeroed.)
