I'm >< close to committing a patch removing all the power_saving
magic from the scheduler. 

Unless someone steps up that says they care about this crap and are
willing to clean it up this goes in...

there is one legitimate choice to make in the scheduler, which is a real
honest preference:
the spread out versus "sort left" preference.

that doesn't need 15 knobs, that needs one.
I can totally buy that this might be easiest done by ripping out all
existing stuff, and then doing something relatively simple
(say, in the, "which CPU to run at" logic, a minor bias)
