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.
