Silencing this warning:
Warning: Kernel ABI header at 'tools/perf/util/hashmap.h' differs from latest version at 'tools/lib/bpf/hashmap.h'
diff -u tools/perf/util/hashmap.h tools/lib/bpf/hashmap.h
I'll eventually update the warning to remove the "Kernel ABI" part
and instead state libbpf when noticing that the original is at
"tools/lib/something".

Any option macro with _SET suffix should set opt->set variable which is
not happening for OPT_CALLBACK_SET(). This is causing issues with perf
record --switch-output-event. Fix that.
Before:
# ./perf record --overwrite -e sched:*switch,syscalls:sys_enter_mmap \
--switch-output-event syscalls:sys_enter_mmap
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.297 MB perf.data (657 samples) ]
After:
$ ./perf record --overwrite -e sched:*switch,syscalls:sys_enter_mmap \
--switch-output-event syscalls:sys_enter_mmap
[ perf record: dump data: Woken up 1 times ]

Pull drm fixes from Dave Airlie:
"Weekly fixes pull, big bigger than I'd normally like, but they are
fairly scattered and small individually.
The vmwgfx one is a black screen regression, otherwise the largest is
an MST encoder fix for amdgpu which results in a WARN in some cases,
and a scattering of i915 fixes.
I'm tracking two regressions at the moment that hopefully we get
nailed down this week for rc7.

opp: Increase parsed_static_opps in _of_add_opp_table_v1()
Currently, when using _of_add_opp_table_v2 parsed_static_opps is
increased and this value is used in _opp_remove_all_static() to
check if there are static opp entries that need to be freed.
Unfortunately this does not happen when using _of_add_opp_table_v1(),
which leads to warnings.
This patch increases parsed_static_opps in _of_add_opp_table_v1() in a
similar way as in _of_add_opp_table_v2().

The afs filesystem driver allows unstarted operations to be cancelled by
signal, but most of these can easily be restarted (mkdir for example). The
primary culprits for reproducing this are those applications that use
SIGALRM to display a progress counter.
File lock-extension operation is marked uninterruptible as we have a
limited time in which to do it, and the release op is marked
uninterruptible also as if we fail to unlock a file, we'll have to wait 20
mins before anyone can lock it again.
The store operation logs a warning if it gets interruption, e.g.:
kAFS: Unexpected error from FS.StoreData -4
because it's run from the background - but it can also be run from
fdatasync()-type things. However, store options aren't marked
interruptible at the moment.
Fix this in the following ways:
(1) Mark store operations as uninterruptible. It might make sense to
relax this for certain situations, but I'm not sure how to make sure
that background store ops aren't affected by signals to foreground
processes that happen to trigger them.
(2) In afs_get_io_locks(), where we're getting the serialisation lock for
talking to the fileserver, return ERESTARTSYS rather than EINTR
because a lot of the operations (e.g. mkdir) are restartable if we
haven't yet started sending the op to the server.

Currently we're failing to recalculate the gen9 FBC w/a stride
unless something more drastic than just the modifier itself has
changed. This often leaves us with FBC enabled with the linear
fbdev framebuffer without the w/a stride enabled. That will cause
an immediate underrun and FBC will get promptly disabled.
Fix the problem by checking if the w/a stride is about to change,
and go through the full dance if so. This part of the FBC code
is still pretty much a disaster and will need lots more work.
But this should at least fix the immediate issue.
v2: Deactivate FBC when the modifier changes since that will
likely require resetting the w/a CFB stride

We do not use the virtual engines for interrupts (they have physical
components), but we do use them to decouple the fence signaling during
submission. Currently, when we submit a completed request, we try to
enable the interrupt handler for the virtual engine, but we never disarm
it. A quick fix is then to mark the irq as enabled, and it will then
remain enabled -- and this prevents us from waking the device and never
letting it sleep again.

Naresh Kamboju reported that the LTP tests can cause warnings on i386
going back all the way to v5.0, and bisected it to commit 2c91bd4a4e2e
("mm: speed up mremap by 20x on large regions").
The warning in move_normal_pmd() is actually mostly correct, but we have
a very unusual special case at process creation time, when we may move
the stack down with an overlapping mode (kind of like a "memmove()"
except using the page tables).
And when you have just the right condition of "move a large initial
stack by the right alignment in the end, but with the early part of the
move being only page-aligned", we'll be in a situation where we're
trying to move a normal PMD entry on top of an already existing - but
now empty - PMD entry.
The warning is still worth having, in case it ever triggers other cases,
and perhaps as a reminder that we could do the stack move case more
efficiently (although it's clearly rare enough that it probably doesn't
matter).
But make it do WARN_ON_ONCE(), so that you can't flood the logs with it.
And add a *big* comment above it to explain and remind us what's going
on, because it took some figuring out to see how this could trigger.
Kudos to Joel Fernandes for debugging this.

Merge tag 'for-5.8-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba:
"Two refcounting fixes and one prepartory patch for upcoming splice
cleanup:
- fix double put of block group with nodatacow
- fix missing block group put when remounting with discard=async
- explicitly set splice callback (no functional change), to ease
integrating splice cleanup patches"
* tag 'for-5.8-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
btrfs: wire up iter_file_splice_write
btrfs: fix double put of block group with nocow
btrfs: discard: add missing put when grabbing block group from unused list
59960b9deb535 ("io_uring: fix lazy work init") tried to fix missing
io_req_init_async(), but left out work.flags and hash. Do it earlier.
Fixes: 7cdaf587de7c ("io_uring: avoid whole io_wq_work copy for requests completed inline")
