Pull scheduler updates from Ingo Molnar:
 "The main changes:

   - load-calculation cleanups and improvements, by Alex Shi
   - various nohz related tidying up of statisics, by Frederic
     Weisbecker
   - factor out /proc functions to kernel/sched/proc.c, by Paul
     Gortmaker
   - simplify the RT policy scheduler, by Kirill Tkhai
   - various fixes and cleanups"
