sched/fair: Replace CFS internal cpu_util() with cpu_util_cfs() (2021-12-11 09:10:00 +0100)

----------------------------------------------------------------
Peter Zijlstra says:

"Mostly minor things this time; some highlights:

- core-sched: Add 'Forced Idle' accounting; this allows to track how
much CPU time is 'lost' due to core scheduling constraints.

- psi: Fix for MEM_FULL; a task running reclaim would be counted as a
runnable task and prevent MEM_FULL from being reported.

- cpuacct: Long standing fixes for some cgroup accounting issues.

- rt: Bandwidth timer could, under unusual circumstances, be failed to
armed, leading to indefinite throttling."

----------------------------------------------------------------
Andrey Ryabinin (4):
cputime, cpuacct: Include guest time in user time in cpuacct.stat
cpuacct: Convert BUG_ON() to WARN_ON_ONCE()
sched/cpuacct: Fix user/system in shown cpuacct.usage*
sched/cpuacct: Make user/system times in cpuacct.stat more precise

Barry Song (1):
sched/fair: Document the slow path and fast path in select_task_rq_fair

Brian Chen (1):
psi: Fix PSI_MEM_FULL state when tasks are in memstall and doing reclaim

Dietmar Eggemann (1):
sched/fair: Replace CFS internal cpu_util() with cpu_util_cfs()

Liu Xinpeng (2):
psi: Remove repeated verbose comment
psi: Add a missing SPDX license header

Vincent Donnefort (3):
sched/fair: Fix detection of per-CPU kthreads waking a task
sched/fair: Fix per-CPU kthread and wakee stacking for asym CPU capacity
sched/fair: Cleanup task_util and capacity type
