#     Pull scheduler fixes from Thomas Gleixner:
#      "A couple of scheduler fixes:
#     
#        - Make the conditional update of the overutilized state work
#          correctly by caching the relevant flags state before overwriting
#          them and checking them afterwards.
#     
#        - Fix a data race in the wakeup path which caused loadavg on ARM64
#          platforms to become a random number generator.
#     
#        - Fix the ordering of the iowaiter accounting operations so it can't
#          be decremented before it is incremented.
#     
#        - Fix a bug in the deadline scheduler vs. priority inheritance when a
#          non-deadline task A has inherited the parameters of a deadline task
#          B and then blocks on a non-deadline task C.
#     
#          The second inheritance step used the static deadline parameters of
#          task A, which are usually 0, instead of further propagating task
#          B's parameters. The zero initialized parameters trigger a bug in
#          the deadline scheduler"
