Subject: [GIT PULL] scheduler fixes

Linus,

   # HEAD: 15257cc2f905dbf5813c0bfdd3c15885f28093c4 sched/fair: Revert force wakeup preemption

Miscellaneous scheduler fixes:

 - Fix PELT clock synchronization bug when entering idle

 - Disable the NEXT_BUDDY feature, as during extensive testing
   Mel found that the negatives outweigh the positives.

 - Make wakeup preemption less aggressive, which resulted in
   an unreasonable increase in preemption frequency.

 Thanks,

	Ingo
