Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Thomas Gleixner:
"A larger set of perf updates.

Not all of them are strictly fixes, but that's solely the tip
maintainers fault as they let the timely -rc1 pull request fall
through the cracks for various reasons including travel. So I'm
sending this nevertheless because rebasing and distangling fixes and
updates would be a mess and risky as well. As of tomorrow, a strict
fixes separation is happening again. Sorry for the slip-up.

Kernel:

- Handle RECORD_MMAP vs. RECORD_MMAP2 correctly so different
consumers of the mmap event get what they requested.

Tools:

- A larger set of updates to perf record/report/scripts vs. time
stamp handling

- More Python3 fixups

- A pile of memory leak plumbing

- perf BPF improvements and fixes

- Finalize the perf.data directory storage"

[ Note: the kernel part is strictly a fix, the updates are purely to
tooling - Linus ]

Merge several updates to the ARS implementation. Highlights include:

* Support retrieval of short-ARS results if the ARS state is "requires
continuation", and even if the "no_init_ars" module parameter is
specified.
* Allow busy-polling of the kernel ARS state by allowing root to reset
the exponential back-off timer.
* Filter potentially stale ARS results by tracking query-ARS relative to
the previous start-ARS.

ASoC: More changes for v5.1

Another batch of changes for ASoC, no big core changes - it's mainly
small fixes and improvements for individual drivers.

- A big refresh and cleanup of the Samsung drivers, fixing a number of
issues which allow the driver to be used with a wider range of
userspaces.
- Fixes for the Intel drivers to make them more standard so less likely
to get bitten by core issues.
- New driver for Cirrus Logic CS35L26.

He Kuang:

- Don't shadow inlined symbol with different addr range.

Jiri Olsa:

- Allow +- operator to ask for -F to add/remove fields to
the default set, for instance to ask for the removal of the
'cpu' field in tracepoint events, adding 'period' to that
kind of events, etc.

Thomas Richter:

- Fix scheduler tracepoint signedness of COMM fields failure of
'evsel-tp-sched' test on s390 and other arches.

Tommi Rantala:

- Skip trace+probe_vfs_getname.sh when 'perf trace' is not built.

perf trace:

Arnaldo Carvalho de Melo:

- Add initial BPF map dumper, initially just for the current, minimal
needs of the augmented_raw_syscalls BPF example used to collect
pointer args payloads that uses BPF maps for pid and syscall filtering,
but will in time have features similar to 'perf stat' --interval-print,
--interval-clear, ways to signal from a BPF event that a specific
map (or range of that map) should be printed, optionally as a
histogram, etc.

General:

Jiri Olsa:

- Add CPU and NUMA topologies classes for further reuse, fixing some
issues in the process.

- Fixup some warnings and debug levels.

- Make rm_rf() remove single file, not just directories.

Documentation:

Jonas Rabenstein:

- Fix HEADER_CMDLINE description in perf.data documentation.

- Fix documentation of the Flags section in perf.data.
