Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar: "The main changes in this cycle were: - refcount conversions - Solve the rq->leaf_cfs_rq_list can of worms for real. - improve power-aware scheduling - add sysctl knob for Energy Aware Scheduling - documentation updates - misc other changes" * 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (34 commits) kthread: Do not use TIMER_IRQSAFE kthread: Convert worker lock to raw spinlock sched/fair: Use non-atomic cpumask_{set,clear}_cpu() sched/fair: Remove unused 'sd' parameter from select_idle_smt() sched/wait: Use freezable_schedule() when possible sched/fair: Prune, fix and simplify the nohz_balancer_kick() comment block sched/fair: Explain LLC nohz kick condition sched/fair: Simplify nohz_balancer_kick() sched/topology: Fix percpu data types in struct sd_data & struct s_data sched/fair: Simplify post_init_entity_util_avg() by calling it with a task_struct pointer argument sched/fair: Fix O(nr_cgroups) in the load balancing path sched/fair: Optimize update_blocked_averages() sched/fair: Fix insertion in rq->leaf_cfs_rq_list sched/fair: Add tmp_alone_branch assertion sched/core: Use READ_ONCE()/WRITE_ONCE() in move_queued_task()/task_rq_lock() sched/debug: Initialize sd_sysctl_cpus if !CONFIG_CPUMASK_OFFSTACK sched/pelt: Skip updating util_est when utilization is higher than CPU's capacity sched/fair: Update scale invariance of PELT sched/fair: Move the rq_of() helper function sched/core: Convert task_struct.stack_refcount to refcount_t ...

+sched_energy_aware:
+
+Enables/disables Energy Aware Scheduling (EAS). EAS starts
+automatically on platforms where it can run (that is,
+platforms with asymmetric CPU topologies and having an Energy
+Model available). If your platform happens to meet the
+requirements for EAS but you do not want to use it, change
+this value to 0.
