[PATCH v2 0/3] DL capacity-aware fixes

[Dietmar Eggemann]

While testing cpusets on asymmetric CPU capacity systems I realized that
the admission control, which kicks in when the cpumask of a cpuset is
about to be changed, is not capacity-aware. [PATCH 2/3] addresses this
issue.

Overview:

[PATCH 1/3] - Not part of the DL related changes but here for
              convenience : Inline helper function around
              static_branch_unlikely(&sched_asym_cpucapacity)

[PATCH 2/3] - Make dl_cpuset_cpumask_can_shrink() capacity-aware.

[PATCH 3/3] - Save a multiplication in dl_task_fits_capacity() by using
	      already maintained dl_density.

v1->v2:

[PATCH 3/3] - s/SCHED_CAPACITY_SHIFT/(BW_SHIFT - SCHED_CAPACITY_SHIFT)
	      (Vincent Guittot)

Dietmar Eggemann (3):
  sched: Introduce sched_asym_cpucap_active()
  sched/deadline: Make dl_cpuset_cpumask_can_shrink() capacity-aware
  sched/deadline: Use sched_dl_entity's dl_density in
    dl_task_fits_capacity()
