Merge tag 'perf-core-for-mingo-4.12-20170320' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

Fixes:

- Fix concat_probe_trace_events() in 'perf probe', it should dereference a
  pointer, not test its value (Ravi Bangoria)

User visible changes:

- Handle partial AUX records, checking if 'kvm_intel.ko' is loaded and
  if its 'vmm_exclusive' parameter is set to 0, suggesting tweaking
  it to reduce gaps (Alexander Shishkin)

Infrastructure changes:

- Sync the kvm.h, cpufeatures.h and perf_event.h tools/ headers copies
  with the kernel (Arnaldo Carvalho de Melo, Alexander Shishkin)

- 'perf lock' subcommands should include common options, using
  OPT_PARENT() (Changbin Du)

- Ditto for 'perf timechart' (Arnaldo Carvalho de Melo)

Documentation changes:

  Correct 'perf stat --no-aggr' description (Ravi Bangoria)
