Subject: [PATCH 0/3] sched: idle: Provide the basis to integrate cpuidle

This patchset provides three patches for the basis to integrate cpuidle with
the scheduler.

The first patch is a cleanup.
The second one adds the sched balance option as requested by Ingo.
The third one stores the idle state a cpu is and adds a rcu_barrier() to
 prevent races when using the pointed object.

This patchset is based on top of v3.15-rc2.

This patchset does not modify the behavior of the scheduler.

Taking into account the cpuidle information from the scheduler will be
posted in a separate patchset in order to keep focused on the right decisions
the scheduler should take regarding the policy vs idle parameters.

Daniel Lezcano (3):
  sched: idle: Encapsulate the code to compile it out
  sched: idle: Add sched balance option
  sched: idle: Store the idle state the cpu is
