Merge tag 'perf-urgent-for-mingo-20161222' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
Fixes for 'perf sched timehist': (Namhyung Kim)
- Define a larger initial alignment value for the COMM column and
make it be more consistently honoured, for instance in the header.
- Fix invalid period calculation when using the --time option to
select a time slice, when events outside that slice were being
considered for the per cpu idle stats summary.
