Subject[GIT PULL] scheduler changes for v4.21
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: 732cd75b8c920d3727e69957b14faa7c2d7c3b75 sched/fair: Select an energy-efficient CPU on task wake-up

The main changes in this cycle were:

- Introduce "Energy Aware Scheduling" - by Quentin Perret. This is a
coherent topology description of CPUs in cooperation with the PM
subsystem, with the goal to schedule more energy-efficiently on
assymetric SMP platform - such as waking up tasks to the more
energy-efficient CPUs first, as long as the system isn't
oversubscribed.

For details of the design, see:

- Misc cleanups and smaller enhancements.

Thanks,

Ingo
