Linus Torvalds edaa5ddf38 Scheduler changes for v5.10: 
- Reorganize & clean up the SD* flags definitions and add a bunch
    of sanity checks. These new checks caught quite a few bugs or at
    least inconsistencies, resulting in another set of patches.
 
  - Rseq updates, add MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ
 
  - Add a new tracepoint to improve CPU capacity tracking
 
  - Improve overloaded SMP system load-balancing behavior
 
  - Tweak SMT balancing
 
  - Energy-aware scheduling updates
 
  - NUMA balancing improvements
 
  - Deadline scheduler fixes and improvements
 
  - CPU isolation fixes
 
  - Misc cleanups, simplifications and smaller optimizations.
