Jin Yao reported parser error for software event:
# perf stat -e software/r1a/ -a -- sleep 1
event syntax error: 'software/r1a/'
\___ parser error
This happens after commit 8c3b1ba0e7 ("drm/i915/gt: Track the
overall awake/busy time"), where new software-gt-awake-time event's
non-pmu-event-style makes event parser conflict with software PMU.
If we allow PE_PMU_EVENT_PRE to be parsed as PMU name, we fix the
conflict and the following character '/' for PMU or '-' for
non-pmu-event-style event allows parser to decide what even is
specified.

This was introduced by commit e4ffd066ff ("perf: Normalize gcc
parameter when generating arch errno table").
Assuming the first word of $(CC) is the actual compiler breaks usage
like CC="ccache gcc": the script ends up calling ccache directly with
gcc arguments, what fails. Instead of getting the first word, just
remove from $(CC) any word that starts with a "-". This maintains the
spirit of the original patch, while not breaking ccache users.

In systems having higher node numbers available like node

Snippet from 'numactl -H' below on a powerpc system where the highest
node number available is 255:
available: 6 nodes (0,8,252-255)
node 0 cpus: <cpu-list>
node 0 size: 519587 MB
node 0 free: 516659 MB
node 8 cpus: <cpu-list>
node 8 size: 523607 MB
node 8 free: 486757 MB
node 252 cpus:
node 252 size: 0 MB
node 252 free: 0 MB
node 253 cpus:
node 253 size: 0 MB
node 253 free: 0 MB
node 254 cpus:
node 254 size: 0 MB
node 254 free: 0 MB
node 255 cpus:
node 255 size: 0 MB
node 255 free: 0 MB
node distances:
node 0 8 252 253 254 255
Note: <cpu-list> expands to actual cpu list in the original output.
These nodes 252-255 are to represent the memory on GPUs and are valid
nodes.
The perf numa bench init code has a condition check to see if the number
of NUMA nodes (nr_nodes) exceeds MAX_NR_NODES. The value of MAX_NR_NODES
defined in perf code is 64. And the 'nr_nodes' is the value from
numa_max_node() which represents the highest node number available in the
system. In some systems where we could have NUMA node 255, this condition
check fails and results in SIGABORT.
The numa benchmark uses static value of MAX_NR_NODES in the code to
represent size of two NUMA node arrays and node bitmask used for setting
memory policy. Patch adds a fix to dynamically allocate size for the
two arrays and bitmask value based on the node numbers available in the
system. With the fix, perf numa benchmark will work with node configuration
on any system and thus removes the static MAX_NR_NODES value.

__cmd_diff() sets result of perf_session__new() to d->session.
In case of failure, it's errno and perf-diff may crash with:
failed to open perf.data: Permission denied

4 cmd_diff (argc=<optimized out>, argv=<optimized out>) at builtin-diff.c:2011
[..]
Funny enough, it won't always crash. For me it crashes only if failed
file is second in cmd-line: the reason is that cmd_diff() check files for
branch-stacks [in check_file_brstack()] and if the first file doesn't
have brstacks, it doesn't proceed to try open other files from cmd-line.
Check d->session before calling perf_session__delete().
Another solution would be assigning to temporary variable, checking it,
but I find it easier to follow with IS_ERR() check in the same function.
After some time it's still obvious why the check is needed, and with
temp variable it's possible to make the same mistake.

Arnaldo reported issue for following build command:

make[1]: *** [Makefile.perf:1010: config-clean] Error 2
make: *** [Makefile:90: clean] Error 2
The problem is that now that we include scripts/Makefile.include
in feature's Makefile (which is fine and needed), we need to ensure
the OUTPUT directory exists, before executing (out of tree) clean
command.
Removing the feature's cleanup from perf Makefile and fixing
feature's cleanup under build Makefile, so it now checks that
there's existing OUTPUT directory before calling the clean.

Merge tag 'io_uring-5.12-2021-03-05' of git://git.kernel.dk/linux-block
Pull io_uring fixes from Jens Axboe:
"A bit of a mix between fallout from the worker change, cleanups and
reductions now possible from that change, and fixes in general. In
detail:
- Fully serialize manager and worker creation, fixing races due to
that.
- Clean up some naming that had gone stale.
- SQPOLL fixes.
- Fix race condition around task_work rework that went into this
merge window.
- Implement unshare. Used for when the original task does unshare(2)
or setuid/seteuid and friends, drops the original workers and forks
new ones.
- Drop the only remaining piece of state shuffling we had left, which
was cred. Move it into issue instead, and we can drop all of that
code too.
- Kill f_op->flush() usage. That was such a nasty hack that we had
out of necessity, we no longer need it.
- Following from ->flush() removal, we can also drop various bits of
ctx state related to SQPOLL and cancelations.
- Fix an issue with IOPOLL retry, which originally was fallout from a
filemap change (removing iov_iter_revert()), but uncovered an issue
with iovec re-import too late.
- Fix an issue with system suspend.
- Use xchg() for fallback work, instead of cmpxchg().
- Properly destroy io-wq on exec.
- Add create_io_thread() core helper, and use that in io-wq and
io_uring. This allows us to remove various silly completion events
related to thread setup.
- A few error handling fixes.
This should be the grunt of fixes necessary for the new workers, next
week should be quieter. We've got a pending series from Pavel on
cancelations, and how tasks and rings are indexed. Outside of that,
should just be minor fixes. Even with these fixes, we're still killing
a net ~80 lines"

Pull btrfs fixes from David Sterba:
"More regression fixes and stabilization.
Regressions:
- zoned mode
- count zone sizes in wider int types
- fix space accounting for read-only block groups
- subpage: fix page tail zeroing
Fixes:
- fix spurious warning when remounting with free space tree
- fix warning when creating a directory with smack enabled
- ioctl checks for qgroup inheritance when creating a snapshot
- qgroup
- fix missing unlock on error path in zero range
- fix amount of released reservation on error
- fix flushing from unsafe context with open transaction,
potentially deadlocking
- minor build warning fixes"

- Fix big endian conversion for arm64 in recordmcount processing
- Fix timestamp corruption in ring buffer on discarding events
- Fix memory leak in __create_synth_event()
- Skip selftests if tracing is disabled as it will cause them to fail.
Non-functional fixes:
- Fix help text in Kconfig
- Remove duplicate prototype for trace_empty()
- Fix stale comment about the trace_event_call flags.
Self test update:
- Add more information to the validation output of when a
corrupt timestamp is found in the ring buffer, and also
trigger a warning to make sure that tests catch it.

In rxe_comp.c in rxe_completer() the function free_pkt() did not clear skb
which triggered a warning at 'done:' and could possibly at 'exit:'. The
WARN_ONCE() calls are not actually needed. The call to free_pkt() is
moved to the end to clearly show that all skbs are freed.

rxe_rcv_mcast_pkt() dropped a reference to ib_device when no error
occurred causing an underflow on the reference counter. This code is
cleaned up to be clearer and easier to read.

When the noted patch below extending the reference taken by
rxe_get_dev_from_net() in rxe_udp_encap_recv() until each skb is freed it
was not matched by a reference in the loopback path resulting in
underflows.

45d189c606 ("io_uring: replace force_nonblock with flags") did
something strange for io_openat() slicing all issue_flags but
IO_URING_F_NONBLOCK. Not a bug for now, but better to just forward the
flags.
