Pull scheduler fixes from Ingo Molnar:
"Miscellaneous MMCID fixes to address bugs and performance regressions
in the recent rewrite of the SCHED_MM_CID management code:
- Fix livelock triggered by BPF CI testing
- Fix hard lockup on weakly ordered systems
- Simplify the dropping of CIDs in the exit path by removing an
unintended transition phase
- Fix performance/scalability regression on a thread-pool benchmark
by optimizing transitional CIDs when scheduling out"
