Linus Torvalds adb35e8dc9 Scheduler updates: 
- migrate_disable/enable() support which originates from the RT tree and
    is now a prerequisite for the new preemptible kmap_local() API which aims
    to replace kmap_atomic().
 
  - A fair amount of topology and NUMA related improvements
 
  - Improvements for the frequency invariant calculations
 
  - Enhanced robustness for the global CPU priority tracking and decision
    making
 
  - The usual small fixes and enhancements all over the place
