    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"
