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: - Introduce "Energy Aware Scheduling" - by Quentin Perret. This is a coherent topology description of CPUs in cooperation with the PM subsystem, with the goal to schedule more energy-efficiently on asymetric SMP platform - such as waking up tasks to the more energy-efficient CPUs first, as long as the system isn't oversubscribed. For details of the design, see: https://lore.kernel.org/lkml/20180724122521.22109-1-quentin.perret@arm.com/ - Misc cleanups and smaller enhancements" * 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (23 commits) sched/fair: Select an energy-efficient CPU on task wake-up sched/fair: Introduce an energy estimation helper function sched/fair: Add over-utilization/tipping point indicator sched/fair: Clean-up update_sg_lb_stats parameters sched/toplogy: Introduce the 'sched_energy_present' static key sched/topology: Make Energy Aware Scheduling depend on schedutil sched/topology: Disable EAS on inappropriate platforms sched/topology: Add lowest CPU asymmetry sched_domain level pointer sched/topology: Reference the Energy Model of CPUs when available PM: Introduce an Energy Model management framework sched/cpufreq: Prepare schedutil for Energy Aware Scheduling sched/topology: Relocate arch_scale_cpu_capacity() to the internal header sched/core: Remove unnecessary unlikely() in push_*_task() sched/topology: Remove the ::smt_gain field from 'struct sched_domain' sched: Fix various typos in comments sched/core: Clean up the #ifdef block in add_nr_running() sched/fair: Make some variables static sched/core: Create task_has_idle_policy() helper sched/fair: Add lsub_positive() and use it consistently sched/fair: Mask UTIL_AVG_UNCHANGED usages ...
