Subject: [PATCH 0/2] sched: Spare IPI on single task renice

A couple of patches to avoid disturbing nohz_full CPUs when a single
fair task get its priority changed. I should probably check other sched
policies as well...

Frederic Weisbecker (2):
  sched: Spare resched IPI when prio changes on a single fair task
  sched: Use fair:prio_changed() instead of ad-hoc implementation
