Merge tag 'perf-core-for-mingo-4.15-20171003' 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:

- Multithread the synthesizing of PERF_RECORD_ events for pre-existing
  threads in 'perf top', speeding up that phase, greatly improving the
  user experience in systems such as Intel's Knights Mill (Kan Liang)

- 'perf test' fixes for the perf_event_attr test case (Jiri Olsa, Thomas Richter)
