Subject: [GIT PULL] scheduler updates for v5.1

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: ad01423aedaa7c6dd62d560b73a3cb39e6da3901 kthread: Do not use TIMER_IRQSAFE

The main changes in this cycle were:

 - refcount conversions

 - Solve the rq->leaf_cfs_rq_list can of worms for real.

 - improve power-aware scheduling

 - add sysctl knob for Energy Aware Scheduling

 - documentation updates

 - misc other changes

 Thanks,

	Ingo
