    Linus Torvalds authored
    Pull scheduler updates from Ingo Molnar:
     "The main changes in this cycle were:
       - Implement frequency/CPU invariance and OPP selection for
         SCHED_DEADLINE (Juri Lelli)
       - Tweak the task migration logic for better multi-tasking
         workload scalability (Mel Gorman)
       - Misc cleanups, fixes and improvements"
