      drm/amd/display: release spinlock before committing updates to stream · 4de9f38b
      Shirish S authored 
      Currently, amdgpu_do_flip() spinlocks crtc->dev->event_lock and
releases it only after committing updates to the stream.

dc_commit_updates_for_stream() should be moved out of
spinlock for the below reasons:

1. event_lock is supposed to protect access to acrct->pflip_status _only_
2. dc_commit_updates_for_stream() has potential sleep's
   and also its not appropriate to be  in an atomic state
   for such long sequences of code.

      drm/amdgpu:Support new VCN FW version naming convention · 62d5b8e3
      James Zhu authored 
      Support new VCN FW version naming convention:
  [31, 28] for VEP interface major version if applicable
  [27, 24] for decode interface major version
  [23, 20] for encode interface major version
  [19, 12] for encode interface minor version
  [11, 0]  for firmware revision
Bit 20-23, it is encode major and non-zero for new naming convention.
This field is part of version minor and DRM_DISABLED_FLAG in old naming
convention. Since the latest version minor is 0x5B and DRM_DISABLED_FLAG
is zero in old naming convention, this field is always zero so far.
These four bits are used to tell which naming convention is present.

      Merge tag 'xfs-4.18-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux · f5749432
      Linus Torvalds authored 
      Pull xfs fixes from Darrick Wong:
 "Here are some patches for 4.18 to fix regressions, accounting
  problems, overflow problems, and to strengthen metadata validation to
  prevent corruption.

  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.

  Changes since last update:

   - more metadata validation strengthening to prevent crashes.

   - fix extent offset overflow problem when insert_range on a 512b
     block fs

   - fix some off-by-one errors in the realtime fsmap code

   - fix some math errors in the default resblks calculation when free
     space is low

   - fix a problem where stale page contents are exposed via mmap read
     after a zero_range at eof

   - fix accounting problems with per-ag reservations causing statfs
     reports to vary incorrectly"

* tag 'xfs-4.18-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
  xfs: fix fdblocks accounting w/ RMAPBT per-AG reservation
  xfs: ensure post-EOF zeroing happens after zeroing part of a file
  xfs: fix off-by-one error in xfs_rtalloc_query_range
  xfs: fix uninitialized field in rtbitmap fsmap backend
  xfs: recheck reflink state after grabbing ILOCK_SHARED for a write
  xfs: don't allow insert-range to shift extents past the maximum offset
  xfs: don't trip over negative free space in xfs_reserve_blocks
  xfs: allow empty transactions while frozen
  xfs: xfs_iflush_abort() can be called twice on cluster writeback failure
  xfs: More robust inode extent count validation
  xfs: simplify xfs_bmap_punch_delalloc_range

      arm64: Remove unnecessary ISBs from set_{pte,pmd,pud} · 24fe1b0e
      Will Deacon authored 
      Commit 7f0b1bf0 ("arm64: Fix barriers used for page table modifications")
fixed a reported issue with fixmap page-table entries not being visible
to the walker due to a missing DSB instruction. At the same time, it added
ISB instructions to the arm64 set_{pte,pmd,pud} functions, which are not
required by the architecture and make little sense in isolation.

Remove the redundant ISBs.
