Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler changes from Ingo Molnar: "Major changes: - Reworked CPU capacity code, for better SMP load balancing on systems with assymetric CPUs. (Vincent Guittot, Morten Rasmussen) - Reworked RT task SMP balancing to be push based instead of pull based, to reduce latencies on large CPU count systems. (Steven Rostedt) - SCHED_DEADLINE support updates and fixes. (Juri Lelli) - SCHED_DEADLINE task migration support during CPU hotplug. (Wanpeng Li) - x86 mwait-idle optimizations and fixes. (Mike Galbraith, Len Brown) - sched/numa improvements. (Rik van Riel) - various cleanups" * 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (28 commits) sched/core: Drop debugging leftover trace_printk call sched/deadline: Support DL task migration during CPU hotplug sched/core: Check for available DL bandwidth in cpuset_cpu_inactive() sched/deadline: Always enqueue on previous rq when dl_task_timer() fires sched/core: Remove unused argument from init_[rt|dl]_rq() sched/deadline: Fix rt runtime corruption when dl fails its global constraints sched/deadline: Avoid a superfluous check sched: Improve load balancing in the presence of idle CPUs sched: Optimize freq invariant accounting sched: Move CFS tasks to CPUs with higher capacity sched: Add SD_PREFER_SIBLING for SMT level sched: Remove unused struct sched_group_capacity::capacity_orig sched: Replace capacity_factor by usage sched: Calculate CPU's usage statistic and put it into struct sg_lb_stats::group_usage sched: Add struct rq::cpu_capacity_orig sched: Make scale_rt invariant with frequency sched: Make sched entity usage tracking scale-invariant sched: Remove frequency scaling from cpu_capacity sched: Track group sched_entity usage contributions sched: Add sched_avg::utilization_avg_contrib ...
