# 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:
https://marc.info/?l=linux-kernel&m=153243513908731&w=2
- Misc cleanups and smaller enhancements.
Thanks,
Ingo

Looks like my warnings fix never made it in, even after a few pings.
Linus, can you apply directly? Causes warning noise on all !SMP ARM builds:

Thanks and sorry about that!
