Subject: [PATCH -v3 0/9] sched/balancing: Misc updates & cleanups

Improve a handful of things I noticed while looking through the
scheduler balancing code. No change in functionality intended.

Changes in -v3:

 - Fix a show_schedstat() assumption found by Shrikanth Hegde
 - Rename the scheduler softirq handler

Thanks,

	Ingo
