Merge tag 'perf-urgent-for-mingo-4.16-20180205' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

- Fix 'period' and 'freq' handling for 'perf record', also
  related: add Add PERF_SAMPLE_PERIOD into PEBS_FREERUNNING_FLAGS
  in the x86 perf kernel driver (Jiri Olsa)

- Fix 'perf trace -i perf.data' callgraph handling (Ravi Bangoria)

- Synchronize tooling headers for asound, s390 and powerpc KVM,
  sched and x86 features (Arnaldo Carvalho de Melo)
