    This reverts commit a8cfae4187efe2756d4152febf6472de4d5ac2f9.
    
    We've reverted boosting mechanism by commits:
      28a9251d7129c ("Revert "ve/sched: port boosting hacks against prio
                      inversion"")
      3ad70f5be8a36 ("Revert "sched: add WARN_ON's to debug task boosting"")
    
    So remove its users as well.
