      Pull kvm updates from Paolo Bonzini:
       "ARM:
         - GICv4.1 support
      
         - 32bit host removal
      
        PPC:
         - secure (encrypted) using under the Protected Execution Framework
           ultravisor
      
        s390:
         - allow disabling GISA (hardware interrupt injection) and protected
           VMs/ultravisor support.
      
        x86:
         - New dirty bitmap flag that sets all bits in the bitmap when dirty
           page logging is enabled; this is faster because it doesn't require
           bulk modification of the page tables.
      
         - Initial work on making nested SVM event injection more similar to
           VMX, and less buggy.
      
         - Various cleanups to MMU code (though the big ones and related
           optimizations were delayed to 5.8). Instead of using cr3 in
           function names which occasionally means eptp, KVM too has
           standardized on "pgd".
      
         - A large refactoring of CPUID features, which now use an array that
           parallels the core x86_features.
      
         - Some removal of pointer chasing from kvm_x86_ops, which will also
           be switched to static calls as soon as they are available.
      
         - New Tigerlake CPUID features.
      
         - More bugfixes, optimizations and cleanups.
      
        Generic:
         - selftests: cleanups, new MMU notifier stress test, steal-time test
      
         - CSV output for kvm_stat"

      Pull xfs updates from Darrick Wong:
       "There's a lot going on this cycle with cleanups in the log code, the
        btree code, and the xattr code.
      
        We're tightening of metadata validation and online fsck checking, and
        introducing a common btree rebuilding library so that we can refactor
        xfs_repair and introduce online repair in a future cycle.
      
        We also fixed a few visible bugs -- most notably there's one in
        getdents that we introduced in 5.6; and a fix for hangs when disabling
        quotas.
      
        This series has been running fstests & other QA in the background for
        over a week and looks good so far.
      
        I anticipate sending a second pull request next week. That batch will
        change how xfs interacts with memory reclaim; how the log batches and
        throttles log items; how hard writes near ENOSPC will try to squeeze
        more space out of the filesystem; and hopefully fix the last of the
        umount hangs after a catastrophic failure. That should ease a lot of
        problems when running at the limits, but for now I'm leaving that in
        for-next for another week to make sure we got all the subtleties
        right.
      
        Summary:
      
         - Fix a hard to trigger race between iclog error checking and log
           shutdown.
      
         - Strengthen the AGF verifier.
      
         - Ratelimit some of the more spammy error messages.
      
         - Remove the icdinode uid/gid members and just use the ones in the
           vfs inode.
      
         - Hold ILOCK across insert/collapse range.
      
         - Clean up the extended attribute interfaces.
      
         - Clean up the attr flags mess.
      
         - Restore PF_MEMALLOC after exiting xfsaild thread to avoid
           triggering warnings in the process accounting code.
      
         - Remove the flexibly-sized array from struct xfs_agfl to eliminate
           compiler warnings about unaligned pointers and packed structures.
      
         - Various macro and typedef removals.
      
         - Stale metadata buffers if we decide they're corrupt outside of a
           verifier.
      
         - Check directory data/block/free block owners.
      
         - Fix a UAF when aborting inactivation of a corrupt xattr fork.
      
         - Teach online scrub to report failed directory and attr name lookups
           as a metadata corruption instead of a runtime error.
      
         - Avoid potential buffer overflows in sysfs files by using scnprintf.
      
         - Fix a regression in getdents lookups due to a mistake in pointer
           arithmetic.
      
         - Refactor btree cursor private data structures to use anonymous
           unions.
      
         - Cleanups in the log unmounting code.
      
         - Fix a potential mishandling of ENOMEM errors on multi-block
           directory buffer lookups.
      
         - Fix an incorrect test in the block allocation code.
      
         - Cleanups and name prefix shortening in the scrub code.
      
         - Introduce btree bulk loading code for online repair and scrub.
      
         - Fix a quotaoff log item leak (and hang) when the fs goes down
           midway through a quotaoff operation.
      
         - Remove di_version from the incore inode.
      
         - Refactor some of the log shutdown checking code.
      
         - Record the forcing of the log unmount records in the log force
           counters.
      
         - Fix a longstanding bug where quotacheck would purge the
           administrator's default quota grace interval and warning limits.
      
         - Reduce memory usage when scrubbing directory and xattr trees.
      
         - Don't let fsfreeze race with GETFSMAP or online scrub.
      
         - Handle bio_add_page failures more gracefully in xlog_write_iclog"
