[GIT PULL] Scheduler updates for v6.18

Linus,

Please pull the latest sched/core Git tree from:

   # HEAD: 45b7f780739a3145aeef24d2dfa02517a6c82ed6 sched: Fix some typos in include/linux/preempt.h

( Merge note: we've stopped using Link tags for the purpose of tip-bot 
  lkml email notifications during the v6.18 development window, and 
  thus commits applied after September 15-ish only have Links if they 
  are particularly informative. Commits before that still have the 
  old-style Link tags. )

Scheduler updates for v6.18:

Core scheduler changes:

 - Make migrate_{en,dis}able() inline, to improve performance
   (Menglong Dong)

 - Move STDL_INIT() functions out-of-line (Peter Zijlstra)

 - Unify the SCHED_{SMT,CLUSTER,MC} Kconfig (Peter Zijlstra)

Fair scheduling:

 - Defer throttling when tasks exit to user-space, to reduce the
   chance & impact of throttle-preemption with held locks and
   other resources. (Aaron Lu, Valentin Schneider)

 - Get rid of sched_domains_curr_level hack for tl->cpumask(),
   as the warning was getting triggered on certain topologies.
   (Peter Zijlstra)

Misc cleanups & fixes:

 - Header cleanups (Menglong Dong)

 - Fix race in push_dl_task() (Harshit Agarwal)

 Thanks,

	Ingo
