       "Some reworks to better support nvdimms on powerpc and an nvdimm
        security interface update:
      
         - Rework the nvdimm core to accommodate architectures with different
           page sizes and ones that can change supported huge page sizes at
           boot time rather than a compile time constant.
      
         - Introduce a distinct 'frozen' attribute for the nvdimm security
           state since it is independent of the locked state.
      
         - Miscellaneous fixups"

      Pull device mapper updates from Mike Snitzer:
      
       - crypto and DM crypt advances that allow the crypto API to reclaim
         implementation details that do not belong in DM crypt. The wrapper
         template for ESSIV generation that was factored out will also be used
         by fscrypt in the future.
      
       - Add root hash pkcs#7 signature verification to the DM verity target.
      
       - Add a new "clone" DM target that allows for efficient remote
         replication of a device.
      
       - Enhance DM bufio's cache to be tailored to each client based on use.
         Clients that make heavy use of the cache get more of it, and those
         that use less have reduced cache usage.
      
       - Add a new DM_GET_TARGET_VERSION ioctl to allow userspace to query the
         version number of a DM target (even if the associated module isn't
         yet loaded).
      
       - Fix invalid memory access in DM zoned target.
      
       - Fix the max_discard_sectors limit advertised by the DM raid target;
         it was mistakenly storing the limit in bytes rather than sectors.
      
       - Small optimizations and cleanups in DM writecache target.

         of DM persistent data library.

      Pull hmm updates from Jason Gunthorpe:
       "This is more cleanup and consolidation of the hmm APIs and the very
        strongly related mmu_notifier interfaces. Many places across the tree
        using these interfaces are touched in the process. Beyond that a
        cleanup to the page walker API and a few memremap related changes
        round out the series:
      
         - General improvement of hmm_range_fault() and related APIs, more
           documentation, bug fixes from testing, API simplification &
           consolidation, and unused API removal
      
         - Simplify the hmm related kconfigs to HMM_MIRROR and DEVICE_PRIVATE,
           and make them internal kconfig selects
      
         - Hoist a lot of code related to mmu notifier attachment out of
           drivers by using a refcount get/put attachment idiom and remove the
           convoluted mmu_notifier_unregister_no_release() and related APIs.
      
         - General API improvement for the migrate_vma API and revision of its
           only user in nouveau
      
         - Annotate mmu_notifiers with lockdep and sleeping region debugging
      
        Two series unrelated to HMM or mmu_notifiers came along due to
        dependencies:
      
         - Allow pagemap's memremap_pages family of APIs to work without
           providing a struct device

      Pull asm inline support from Miguel Ojeda:
       "Make use of gcc 9's "asm inline()" (Rasmus Villemoes):
      
        gcc 9+ (and gcc 8.3, 7.5) provides a way to override the otherwise
        crude heuristic that gcc uses to estimate the size of the code
        represented by an asm() statement. From the gcc docs
      
            If you use 'asm inline' instead of just 'asm', then for inlining
            purposes the size of the asm is taken as the minimum size, ignoring
            how many instructions GCC thinks it is.
      
        For compatibility with older compilers, we obviously want a
      
            #if [understands asm inline]
            #define asm_inline asm inline
            #else
            #define asm_inline asm
            #endif
      
        But since we #define the identifier inline to attach some attributes,
        we have to use an alternate spelling of that keyword. gcc provides
        both __inline__ and __inline, and we currently #define both to inline,
        so they all have the same semantics.
      
        We have to free up one of __inline__ and __inline, and the latter is
        by far the easiest.
      
        The two x86 changes cause smaller code gen differences than I'd
        expect, but I think we do want the asm_inline thing available sooner
        or later, so this is just to get the ball rolling"

      Pull ARM SoC late updates from Arnd Bergmann:
       "This is some material that we picked up into our tree late or that had
        complex inter-depondencies. The fact that there are these
        interdependencies tends to meant that these are often actually the
        most interesting new additions:
      
         - The new Aspeed AST2600 baseboard management controller is added,
           this is a Cortex-A7 based follow-up to the ARM11 based AST2500 and
           had some dependencies on other device drivers.
      
         - After many years, support for the MMP2 based OLPC XO-1.75 finally
           makes it into the kernel.
      
         - The Armada 3720 based Turris Mox open source router platform is a
           late addition and it follows some preparatory work across multiple
           branches.
      
         - The OMAP2+ platform had some large-scale cleanup involving driver
           changes and DT changes, here we finish it off, dropping a lot of
           the now-unused platform data.
      
         - The TI K3 platform that got added for 5.3 gains a lot more support
           for individual bits on the SoC, this part just came late for the
           merge window"
      
      [ This pull request itself wasn't actually sent late at all by Arnd, but
        I waited on the branches that it used to be pulled first, so it ends
        up being merged much later than the other ARM SoC pull requests this

      Pull clk updates from Stephen Boyd:
       "We have a small collection of core framework updates this time, mostly
        around clk registration by clk providers and debugfs "nice to haves"
        for rate constraints. I'll highlight that we're now setting the
        clk_init_data pointer inside struct clk_hw to NULL during
        clk_register(), which may break some drivers that thought they could
        use that pointer during normal operations. That change has been
        sitting in next for a while now but maybe something is still broken.
        We'l see. Other than that the core framework changes aren't invasive
        and they're fixing bugs, simplifying, and making things better.
      
        On the clk driver side we got the usual addition of new SoC support,
        new features for existing drivers, and bug fixes scattered throughout.
        The biggest diffstat is the Amlogic driver that gained CPU clk support
        in addition to migrating to the new way of specifying clk parents.
        After that the Qualcomm, i.MX, Mediatek, and Rockchip clk drivers got
        support for various new SoCs and clock controllers from those vendors.
      
        Core:
         - Drop NULL checks in clk debugfs
         - Add min/max rates to clk debugfs
         - Set clk_init_data pointer inside clk_hw to NULL after registration
         - Make clk_bulk_get_all() return an 'id' corresponding to clock-names
         - Evict parents from parent cache when they're unregistered
      
        New Drivers:
         - Add clock driver for i.MX8MN SoCs
         - Support aspeed AST2600 SoCs
         - Support for Mediatek MT6779 SoCs

         - Initial support for running on a system with an Ultravisor, which
           is software that runs below the hypervisor and protects guests
           against some attacks by the hypervisor.
      
         - Support for building the kernel to run as a "Secure Virtual
           Machine", ie. as a guest capable of running on a system with an
           Ultravisor.
      
         - Some changes to our DMA code on bare metal, to allow devices with
           medium sized DMA masks (> 32 && < 59 bits) to use more than 2GB of
           DMA space.
      
         - Support for firmware assisted crash dumps on bare metal (powernv).
      
         - Two series fixing bugs in and refactoring our PCI EEH code.
      
         - A large series refactoring our exception entry code to use gas
           macros, both to make it more readable and also enable some future
           optimisations.
      
        As well as many cleanups and other minor features & fixups.

       "This is the main pull request for 5.4-rc1 merge window. I don't think
        there is anything outstanding so next week should just be fixes, but
        we'll see if I missed anything. I landed some fixes earlier in the
        week but got delayed writing summary and sending it out, due to a mix
        of sick kid and jetlag!
      
        There are some fixes pending, but I'd rather get the main merge out of
        the way instead of delaying it longer.
      
        It's also pretty large in commit count and new amd header file size.
        The largest thing is four new amdgpu products (navi12/14, arcturus and
        renoir APU support).
      
        Otherwise it's pretty much lots of work across the board, i915 has
        started landing tigerlake support, lots of icelake fixes and lots of
        locking reworking for future gpu support, lots of header file rework
        (drmP.h is nearly gone), some old legacy hacks (DRM_WAIT_ON) have been
        put into the places they are needed.

      clk: Drop !clk checks in debugfs dumping · 7f480466
      Stephen Boyd authored
      These recursive functions have checks for !clk being passed in, but the
      callers are always looping through lists and therefore the pointers
      can't be NULL. Drop the checks to simplify the code.

       - input core allows hardware drivers to specify a [more precise]
         timestamp (normally taken in top half) to better track velocity of

       "Add inode timestamp clamping.
      
        This series from Deepa Dinamani adds a per-superblock minimum/maximum
        timestamp limit for a file system, and clamps timestamps as they are
        written, to avoid random behavior from integer overflow as well as
        having different time stamps on disk vs in memory.
      
        At mount time, a warning is now printed for any file system that can
        represent current timestamps but not future timestamps more than 30
        years into the future, similar to the arbitrary 30 year limit that was
        added to settimeofday().
      
        This was picked as a compromise to warn users to migrate to other file
        systems (e.g. ext4 instead of ext3) when they need the file system to
        survive beyond 2038 (or similar limits in other file systems), but not
        get in the way of normal usage"
