Subject: [PATCH 4/6] perf, tools, stat: Move noise/running printing into printout

From: Andi Kleen <ak@...ux.intel.com>

Move the running/noise printing into printout to avoid
duplicated code in the callers.

v2: Merged with other patches. Remove unnecessary hunk.
Readd hunk that ended in earlier patch.
Signed-off-by: Andi Kleen <ak@...ux.intel.com>
