   # HEAD: f31dcb152a3d0816e2f1deab4e64572336da197d sched/clock: Fix local_clock() before sched_clock_init()

Scheduler changes for v6.4:

 - Allow unprivileged PSI poll()ing

 - Fix performance regression introduced by mm_cid

 - Improve livepatch stalls by adding livepatch task switching to cond_resched(),
   this resolves livepatching busy-loop stalls with certain CPU-bound kthreads.

 - Improve sched_move_task() performance on autogroup configs.

 - On core-scheduling CPUs, avoid selecting throttled tasks to run

 - Misc cleanups, fixes and improvements.

 Thanks,

	Ingo
