Merge tag 'sched-core-2022-05-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar: - Updates to scheduler metrics: - PELT fixes & enhancements - PSI fixes & enhancements - Refactor cpu_util_without() - Updates to instrumentation/debugging: - Remove sched_trace_*() helper functions - can be done via debug info - Fix double update_rq_clock() warnings - Introduce & use "preemption model accessors" to simplify some of the Kconfig complexity. - Make softirq handling RT-safe. - Misc smaller fixes & cleanups. * tag 'sched-core-2022-05-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: topology: Remove unused cpu_cluster_mask() sched: Reverse sched_class layout sched/deadline: Remove superfluous rq clock update in push_dl_task() sched/core: Avoid obvious double update_rq_clock warning smp: Make softirq handling RT safe in flush_smp_call_function_queue() smp: Rename flush_smp_call_function_from_idle() sched: Fix missing prototype warnings sched/fair: Remove cfs_rq_tg_path() sched/fair: Remove sched_trace_*() helper functions sched/fair: Refactor cpu_util_without() sched/fair: Revise comment about lb decision matrix sched/psi: report zeroes for CPU full at the system level sched/fair: Delete useless condition in tg_unthrottle_up() sched/fair: Fix cfs_rq_clock_pelt() for throttled cfs_rq sched/fair: Move calculate of avg_load to a better location mailmap: Update my email address to @redhat.com MAINTAINERS: Add myself as scheduler topology reviewer psi: Fix trigger being fired unexpectedly at initial ftrace: Use preemption model accessors for trace header printout kcsan: Use preemption model accessors
