Subject: [GIT PULL] scheduler updates for v3.16, #2

Linus,

Please pull the latest sched-core-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-core-for-linus

   # HEAD: 535560d841b2d54f31280e05e9c6ffd19da0c4e7 Merge commit '3cf2f34' into sched/core, to fix build error

Second round of scheduler changes:

 - try-to-wakeup and IPI reduction speedups, from Andy Lutomirski

 - continued power scheduling cleanups and refactorings, from Nicolas Pitre

 - misc fixes and enhancements

Thanks,

	Ingo
