Merge tag 'sched-core-2022-12-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar: - Implement persistent user-requested affinity: introduce affinity_context::user_mask and unconditionally preserve the user-requested CPU affinity masks, for long-lived tasks to better interact with cpusets & CPU hotplug events over longer timespans, without destroying the original affinity intent if the underlying topology changes. - Uclamp updates: fix relationship between uclamp and fits_capacity() - PSI fixes - Misc fixes & updates * tag 'sched-core-2022-12-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched: Clear ttwu_pending after enqueue_task() sched/psi: Use task->psi_flags to clear in CPU migration sched/psi: Stop relying on timer_pending() for poll_work rescheduling sched/psi: Fix avgs_work re-arm in psi_avgs_work() sched/psi: Fix possible missing or delayed pending event sched: Always clear user_cpus_ptr in do_set_cpus_allowed() sched: Enforce user requested affinity sched: Always preserve the user requested cpumask sched: Introduce affinity_context sched: Add __releases annotations to affine_move_task() sched/fair: Check if prev_cpu has highest spare cap in feec() sched/fair: Consider capacity inversion in util_fits_cpu() sched/fair: Detect capacity inversion sched/uclamp: Cater for uclamp in find_energy_efficient_cpu()'s early exit condition sched/uclamp: Make cpu_overutilized() use util_fits_cpu() sched/uclamp: Make asym_fits_capacity() use util_fits_cpu() sched/uclamp: Make select_idle_capacity() use util_fits_cpu() sched/uclamp: Fix fits_capacity() check in feec() sched/uclamp: Make task_fits_capacity() use util_fits_cpu() sched/uclamp: Fix relationship between uclamp and migration margin
