[GIT PULL] scheduler changes for v6.2

[Ingo Molnar]

Linus,

Please pull the latest scheduler tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-core-2022-12-12

   # HEAD: d6962c4fe8f96f7d384d6489b6b5ab5bf3e35991 sched: Clear ttwu_pending after enqueue_task()

Scheduler changes for v6.2:

 - 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.

 Thanks,

	Ingo
