       "This is mostly updates to the usual drivers: ufs, qedf, mpt3sas, lpfc,
        xfcp, hisi_sas, cxlflash, qla2xxx.
        In the absence of Nic, we're also taking target updates which are
        mostly minor except for the tcmu refactor.
        The only real core change to worry about is the removal of high page
        bouncing (in sas, storvsc and iscsi). This has been well tested and no
        problems have shown up so far"

      Pull x86 updates and fixes from Thomas Gleixner:
       - Fix the (late) fallout from the vector management rework causing
         hlist corruption and irq descriptor reference leaks caused by a
         missing sanity check.
         The straight forward fix triggered another long standing issue to
         surface. The pre rework code hid the issue due to being way slower,
         but now the chance that user space sees an EBUSY error return when
         updating irq affinities is way higher, though quite a bunch of
         userspace tools do not handle it properly despite the fact that EBUSY
         could be returned for at least 10 years.
         It turned out that the EBUSY return can be avoided completely by
         utilizing the existing delayed affinity update mechanism for irq
         remapped scenarios as well. That's a bit more error handling in the
         kernel, but avoids fruitless fingerpointing discussions with tool
       - Decouple PHYSICAL_MASK from AMD SME as its going to be required for
         the upcoming Intel memory encryption support as well.

       - Fix the wrong argument ordering in the vector allocation tracepoint
       - Simplify the IDT setup code for the APIC=n case
       - Use the proper string helpers in the MTRR code
       - Remove a stale unused VDSO source file
       - Convert the microcode update lock to a raw spinlock as its used in
         atomic context.

      Commit a841796f ("signal: align __lock_task_sighand() irq disabling and

      disabled. The changelog suggested that a better long-term fix would be "to
      make rt_mutex_unlock() disable irqs when acquiring the rt_mutex structure's
      This long-term fix has been made in commit b4abf910 ("rtmutex: Make
      wait_lock irq safe") for a different reason.
      Therefore revert commit a841796f ("signal: align >
      __lock_task_sighand() irq disabling and RCU") as the interrupt disable
      dance is not longer required.
      The change was tested on the base of b4abf910 ("rtmutex: Make wait_lock
      irq safe") with a four hour run of rcutorture scenario TREE03 with lockdep
      enabled as suggested by Paul McKenney.

      Linus Torvalds authored
      Merge proc_cmdline simplifications.
      This re-writes the get_mm_cmdline() logic to be rather simpler than it
      used to be, and makes the semantics for "cmdline goes past the end of
      the original area" more natural.
      You _can_ use prctl(PR_SET_MM) to just point your command line somewhere
      else entirely, but the traditional model is to just edit things in place
      and that still needs to continue to work.  At least this way the code
      makes some sense.

      Pull clk updates from Stephen Boyd:
       "This time we have a good set of changes to the core framework that do
        some general cleanups, but nothing too major. The majority of the diff
        goes to two SoCs, Actions Semi and Qualcomm. A brand new driver is
        introduced for Actions Semi so it takes up some lines to add all the
        different types, and the Qualcomm diff is there because we add support
        for two SoCs and it's quite a bit of data.
        Otherwise the big driver updates are on TI Davinci and Amlogic
        platforms. And then the long tail of driver updates for various fixes
        and stuff follows after that.
         - debugfs cleanups removing error checking and an unused provider API
         - Removal of a clk init typedef that isn't used
         - Usage of match_string() to simplify parent string name matching
         - OF clk helpers moved to their own file (linux/of_clk.h)
         - Make clk warnings more readable across kernel versions
        New Drivers:
         - Qualcomm SDM845 GCC and Video clk controllers
         - Qualcomm MSM8998 GCC
         - Actions Semi S900 SoC support
         - Nuvoton npcm750 microcontroller clks

        Removed Drivers:
         - Deprecated Rockchip clk-gate driver
         - debugfs functions stopped checking return values
         - Support for the MSIOF module clocks on Rensas R-Car M3-N
         - Support for the new Rensas RZ/G1C and R-Car E3 SoCs
         - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs
         - Berlin and Amlogic SPDX tagging
         - Usage of of_clk_get_parent_count() in more places
         - Proper implementation of the CDEV1/2 clocks on Tegra20
         - Allwinner H6 PRCM clock support and R40 EMAC support
         - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet

      Pull staging/IIO updates from Greg KH:
       "Here is the big staging and IIO driver update for 4.18-rc1.
        It was delayed as I wanted to make sure the final driver deletions did
        not cause any major merge issues, and all now looks good.
        There are a lot of patches here, just over 1000. The diffstat summary
        shows the major changes here:
      	1007 files changed, 16828 insertions(+), 227770 deletions(-)
        Because of this, we might be close to shrinking the overall kernel
        source code size for two releases in a row.
        There was loads of work in this release cycle, primarily:
         - tons of ks7010 driver cleanups
         - lots of mt7621 driver fixes and cleanups
         - most driver cleanups
         - wilc1000 fixes and cleanups
         - lots and lots of IIO driver cleanups and new additions
         - debugfs cleanups for all staging drivers
         - lots of other staging driver cleanups and fixes, the shortlog has
           the full details.
        but the big user-visable things here are the removal of 3 chunks of
         - ncpfs and ipx were removed on schedule, no one has cared about this
           code since it moved to staging last year, and if it needs to come
           back, it can be reverted.
         - lustre file system is removed.
           I've ranted at the lustre developers about once a year for the past
           5 years, with no real forward progress at all to clean things up
           and get the code into the "real" part of the kernel.
           Given that the lustre developers continue to work on an external
           tree and try to port those changes to the in-kernel tree every once
           in a while, this whole thing really really is not working out at
           all. So I'm deleting it so that the developers can spend the time
           working in their out-of-tree location and get things cleaned up
           properly to get merged into the tree correctly at a later date.
        Because of these file removals, you will have merge issues on some of
        these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
        atomisp driver). Just delete those files, it's a simple merge :)

      A recent commit reused the original request flags for the flush
      queue handling. However, for some of the kick flush cases, the
      original request was already completed. This caused a use after
      free, if blk-mq wasn't used.

       "This adds a user for the new 'bytes-remaining' updates to
        memcpy_mcsafe() that you already received through Ingo via the
        x86-dax- for-linus pull.
        Not included here, but still targeting this cycle, is support for
        handling memory media errors (poison) consumed via userspace dax
         - DAX broke a fundamental assumption of truncate of file mapped
           pages. The truncate path assumed that it is safe to disconnect a
           pinned page from a file and let the filesystem reclaim the physical
           block. With DAX the page is equivalent to the filesystem block.
           Introduce dax_layout_busy_page() to enable filesystems to wait for
           pinned DAX pages to be released. Without this wait a filesystem
           could allocate blocks under active device-DMA to a new file.
         - DAX arranges for the block layer to be bypassed and uses
           dax_direct_access() + copy_to_iter() to satisfy read(2) calls.
           However, the memcpy_mcsafe() facility is available through the pmem
           block driver. In order to safely handle media errors, via the DAX
           block-layer bypass, introduce copy_to_iter_mcsafe().
