[PATCH 057/107] libperf: Add perf_cpu_map__get()/perf_cpu_map__put()

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Jiri Olsa <jolsa@kernel.org>

Moving the following functions:

  cpu_map__get()
  cpu_map__put()

to libperf with following names:

  perf_cpu_map__get()
  perf_cpu_map__put()

Committer notes:

Added fixes for arm/arm64
