Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler changes from Ingo Molnar: "Bigger changes: - sched/idle restructuring: they are WIP preparation for deeper integration between the scheduler and idle state selection, by Nicolas Pitre. - add NUMA scheduling pseudo-interleaving, by Rik van Riel. - optimize cgroup context switches, by Peter Zijlstra. - RT scheduling enhancements, by Thomas Gleixner. The rest is smaller changes, non-urgnt fixes and cleanups" * 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (68 commits) sched: Clean up the task_hot() function sched: Remove double calculation in fix_small_imbalance() sched: Fix broken setscheduler() sparc64, sched: Remove unused sparc64_multi_core sched: Remove unused mc_capable() and smt_capable() sched/numa: Move task_numa_free() to __put_task_struct() sched/fair: Fix endless loop in idle_balance() sched/core: Fix endless loop in pick_next_task() sched/fair: Push down check for high priority class task into idle_balance() sched/rt: Fix picking RT and DL tasks from empty queue trace: Replace hardcoding of 19 with MAX_NICE sched: Guarantee task priority in pick_next_task() sched/idle: Remove stale old file sched: Put rq's sched_avg under CONFIG_FAIR_GROUP_SCHED cpuidle/arm64: Remove redundant cpuidle_idle_call() cpuidle/powernv: Remove redundant cpuidle_idle_call() sched, nohz: Exclude isolated cores from load balancing sched: Fix select_task_rq_fair() description comments workqueue: Replace hardcoding of -20 and 19 with MIN_NICE and MAX_NICE sys: Replace hardcoding of -20 and 19 with MIN_NICE and MAX_NICE ...
