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.
