Merge branch 'perf/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf tooling fixes from Arnaldo Carvalho de Melo:
"- Fix window dimensions change handling in 'perf top' (Jiri Olsa)
- Fix 'perf record -c/-F' options for CPU event aliases (Andi Kleen)
- Generate PERF_RECORD_{MMAP,COMM,EXEC} with 'perf record --delay'
fixing symbol resolution for processes created, maps put in place
while --delay happens (Arnaldo Carvalho de Melo)
- Fix up leftover perf_evsel_stat usage via evsel->priv, plugging
a SEGV when using event groups as in:
$ perf stat -e '{cpu-clock,instructions}' workload
- Fix 'perf script --per-event-dump' for auxtrace synth evsels (Arnaldo Carvalho de Melo)
- Ignore kptr_restrict when not sampling the kernel (Arnaldo Carvalho de Melo)
- Synchronize kernel ABI headers wrt SPDX tags and ABI changes,
taking minimal action to handle new syscall args and silencing
perf build warnings (Arnaldo Carvalho de Melo, Ingo Molnar)
- Fix header.size for namespace events (Jiri Olsa)
- Fix a bug during strstart() conversion in 'perf help' (Namhyung Kim)
- Do not truncate instruction names at 6 chars in 'perf annotate', there
are really long instruction names in PPC (Ravi Bangoria)
- Fixup discontiguous/sparse numa nodes in 'perf bench numa' (Satheesh Rajendran)
- Fix an exit code of trace__symbols_init in 'perf trace' (Andrei Vagin)
- Fix 'perf test' entries on s/390 (Thomas Richter)
- Bring instruction decoder files used by Intel PT into line with the kernel,
silencing build warning (Adrian Hunter)"
