[PATCH 0/4] sched: schedule/preempt optimizations and cleanups

[Frederic Weisbecker]

Hey,

This series is based on suggestions from Linus. I posted a previous
version one month ago then Linus suggested more improvements. Here
is the following iteration.

The last patch suggests to (ab)use PREEMPT_ACTIVE to disable preemption
on schedule(). It's optional as it's a possibily controversial cleanup.

Thanks.

Frederic Weisbecker (4):
  sched: Pull resched loop to __schedule() callers
  sched: Use traced preempt count operations to toggle PREEMPT_ACTIVE
  sched: Pull preemption disablement to __schedule() caller
  sched: Account PREEMPT_ACTIVE context as atomic
