Thomas Zimmermann efc8f3229f MAINTAINERS: Broaden scope of simpledrm entry
There will be more DRM drivers for firmware-provided framebuffers. Use
the existing entry for simpledrm instead of adding a new one for each
driver. Also add DRM's aperture helpers, which are part of the driver's
infrastructure.

Jocelyn Falempe 5171660cbb drm/ast: Fix black screen when getting out of suspend
With an AST2600, the screen is garbage when going out of suspend.
This is because color settings are lost, and not restored on resume.
Force the color settings on DPMS_ON, to make sure the settings are correct.

I didn't write this code, it comes from the out-of-tree aspeed driver v1.13

Miaoqian Lin 3a149169e4 drm/mcde: Fix refcount leak in mcde_dsi_bind
Every iteration of for_each_available_child_of_node() decrements
the reference counter of the previous node. There is no decrement
when break out from the loop and results in refcount leak.
Add missing of_node_put() to fix this.

Darrick J. Wong f94e08b602 xfs: clean up the end of xfs_attri_item_recover
The end of this function could use some cleanup -- the EAGAIN
conditionals make it harder to figure out what's going on with the
disposal of xattri_leaf_bp, and the dual error/ret variables aren't
needed.  Turn the EAGAIN case into a separate block documenting all the
subtleties of recovering in the middle of an xattr update chain, which
makes the rest of the prologue much simpler.

This appears to be the result of shortform_to_leaf creating a new leaf
buffer as part of adding an xattr to a file.  The new leaf buffer is
held and attached to the xfs_attr_intent structure, but then the
filesystem shuts down.  Instead of the usual path (which adds the attr
to the held leaf buffer which releases the hold), we instead cancel the
entire deferred operation.

Unfortunately, xfs_attr_cancel_item doesn't release any attached leaf
buffers, so we leak the locked buffer.  The CIL cannot do anything
about that, and hangs.  Fix this by teaching it to release leaf buffers,
and make XFS a little more careful about not leaving a dangling
reference.

The prologue of xfs_attri_item_recover is (in this author's opinion) a
little hard to figure out, so I'll clean that up in the next patch.

Pull cifs client fixes from Steve French:
 "Fixes addressing important multichannel, and reconnect issues.

  Multichannel mounts when the server network interfaces changed, or ip
  addresses changed, uncovered problems, especially in reconnect, but
  the patches for this were held up until recently due to some lock
  conflicts that are now addressed.

  Included in this set of fixes:

   - three fixes relating to multichannel reconnect, dynamically
     adjusting the list of server interfaces to avoid problems during
     reconnect

   - a lock conflict fix related to the above

   - two important fixes for negotiate on secondary channels (null
     netname can unintentionally cause multichannel to be disabled to
     some servers)

   - a reconnect fix (reporting incorrect IP address in some cases)"

Gang Li 448ce0e6ea perf stat: Enable ignore_missing_thread
perf already support ignore_missing_thread for -p, but not yet
applied to `perf stat -p <pid>`. This patch enables ignore_missing_thread
for `perf stat -p <pid>`.

Committer notes:

And here is a refresher about the 'ignore_missing_thread' knob, from a
previous patch using it:

  ca8000684e ("perf evsel: Enable ignore_missing_thread for pid option")

  ---
    While monitoring a multithread process with pid option, perf sometimes
    may return sys_perf_event_open failure with 3(No such process) if any of
    the process's threads die before we open the event. However, we want
    perf continue monitoring the remaining threads and do not exit with
    error.

Raul Silvera 37ed2cddcb perf inject: Adjust output data offset for backward compatibility
When 'perf inject' creates a new file, it reuses the data offset from
the input file. If there has been a change on the size of the header, as
happened in v5.12 -> v5.13, the new offsets will be wrong, resulting in
a corrupted output file.

This change adds the function perf_session__data_offset to compute the
data offset based on the current header size, and uses that instead of
the offset from the original input file.

Adrian Hunter ab66fdace8 perf build-id: Fix caching files with a wrong build ID
Build ID events associate a file name with a build ID.  However, when
using perf inject, there is no guarantee that the file on the current
machine at the current time has that build ID. Fix by comparing the
build IDs and skip adding to the cache if they are different.

Example:

  $ echo "int main() {return 0;}" > prog.c
  $ gcc -o prog prog.c
  $ perf record --buildid-all ./prog
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.019 MB perf.data ]
  $ file-buildid() { file $1 | awk -F= '{print $2}' | awk -F, '{print $1}' ; }
  $ file-buildid prog
  444ad9be165d8058a48ce2ffb4e9f55854a3293e
  $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf
  444ad9be165d8058a48ce2ffb4e9f55854a3293e
  $ echo "int main() {return 1;}" > prog.c
  $ gcc -o prog prog.c
  $ file-buildid prog
  885524d5aaa24008a3e2b06caa3ea95d013c0fc5

Before:

  $ perf buildid-cache --purge $(pwd)/prog
  $ perf inject -i perf.data -o junk
  $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf
  885524d5aaa24008a3e2b06caa3ea95d013c0fc5
  $

After:

  $ perf buildid-cache --purge $(pwd)/prog
  $ perf inject -i perf.data -o junk
  $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf

John David Anglin e9ed22e6e5 parisc: Fix flush_anon_page on PA8800/PA8900
Anonymous pages are allocated with the shared mappings colouring,
SHM_COLOUR. Since the alias boundary on machines with PA8800 and
PA8900 processors is unknown, flush_user_cache_page() might not
flush all mappings of a shared anonymous page. Flushing the whole
data cache flushes all mappings.

This won't fix all coherency issues with shared mappings but it
seems to work well in practice.  I haven't seen any random memory
faults in almost a month on a rp3440 running as a debian buildd
machine.

There is a small preformance hit.
