 discovered
that this patch doesn't build anymore (on tip sched/core or linux-next)
because of commit f5b2eeb4 ("sched/fair: Consider CPU affinity when
allowing NUMA imbalance in find_idlest_group()").

New version of [PATCH v11 4/7] sched/fair: Rename select_idle_mask to
select_rq_mask below.

-- >8 --

Decouple the name of the per-cpu cpumask select_idle_mask from its usage
in select_idle_[cpu/capacity]() of the CFS run-queue selection
(select_task_rq_fair()).

This is to support the reuse of this cpumask in the Energy Aware
Scheduling (EAS) path (find_energy_efficient_cpu()) of the CFS run-queue
selection.
