Merge tag 'sched-core-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar: - reorganize & clean up the SD* flags definitions and add a bunch of sanity checks. These new checks caught quite a few bugs or at least inconsistencies, resulting in another set of patches. - rseq updates, add MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ - add a new tracepoint to improve CPU capacity tracking - improve overloaded SMP system load-balancing behavior - tweak SMT balancing - energy-aware scheduling updates - NUMA balancing improvements - deadline scheduler fixes and improvements - CPU isolation fixes - misc cleanups, simplifications and smaller optimizations * tag 'sched-core-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (42 commits) sched/deadline: Unthrottle PI boosted threads while enqueuing sched/debug: Add new tracepoint to track cpu_capacity sched/fair: Tweak pick_next_entity() rseq/selftests: Test MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ rseq/selftests,x86_64: Add rseq_offset_deref_addv() rseq/membarrier: Add MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ sched/fair: Use dst group while checking imbalance for NUMA balancer sched/fair: Reduce busy load balance interval sched/fair: Minimize concurrent LBs between domain level sched/fair: Reduce minimal imbalance threshold sched/fair: Relax constraint on task's load during load balance sched/fair: Remove the force parameter of update_tg_load_avg() sched/fair: Fix wrong cpu selecting from isolated domain sched: Remove unused inline function uclamp_bucket_base_value() sched/rt: Disable RT_RUNTIME_SHARE by default sched/deadline: Fix stale throttling on de-/boosted tasks sched/numa: Use runnable_avg to classify node sched/topology: Move sd_flag_debug out of #ifdef CONFIG_SYSCTL MAINTAINERS: Add myself as SCHED_DEADLINE reviewer sched/topology: Move SD_DEGENERATE_GROUPS_MASK out of linux/sched/topology.h ...
