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

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

Infrastructure changes:

  - Reference count the cpu_map and thread_map classes. (Jiri Olsa)

  - Set evsel->{cpus,threads} from the evlist, if not set,
    allowing the generalization of some 'perf stat' functions that
    previously were accessing private static evlist variable. (Jiri Olsa)

  - Delete an unnecessary check before the calling
    free_event_desc() (Markus Elfring)
