   # 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
