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)"
