So I wanted to give you some feedback for this, from the scheduler maintainer's 
POV.

Looks like there are two cpufreq modernization efforts, one is this series, the 
other is Steve Muckle's:

  [RFCv7 PATCH 00/10] sched: scheduler-driven CPU frequency selection

What I'd like to see from a scheduler metrics usage POV is a single central place, 
kernel/sched/cpufreq.c, where all the high level ('governor') decisions are made.  
This is the approach Steve's series takes.

That is a central point that has ready access to the scheduler internal 
utilization metrics.

drivers/cpufreq/ would contain legacy governors plus low level drivers that do 
frequency switching with a well-defined interface.

Could you guys work out a single series that implements the sum of the two series? 
Looks like we are 90% 'there' already.

Thanks,

	Ingo
