'schedutil' cpufreq policy governor

modulename: cpufreq_schedutil.ko

In linux kernel since version 3.10 (release Date: 2013-06-30)  
This governor makes decisions based on the utilization data provided
by the scheduler. It sets the CPU frequency to be proportional to
the utilization/capacity ratio coming from the scheduler. If the
utilization is frequency-invariant, the new frequency is also
proportional to the maximum available frequency. If that is not the
case, it is proportional to the current frequency of the CPU. The
frequency tipping point is at utilization/capacity equal to 80% in
both cases.

If in doubt, say N.
