Subject: [PATCHv2 0/3] perf tools: Add perf_event_max_sample_rate freq check

hi,
adding the check for maximum allowed frequency rate
defined in perf_event_max_sample_rate.

Plus procfs mountpoint reading code. Reachable here:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/max_rate

v2 changes:
  naming changes suggested by Arnaldo in patch 1/3
  patch 3/3:
    - unify freq. config code for record and top
    - add warning for default rate crossing the max
