We are going to use runnable_avg_sum and runnable_avg_period in order to get
the utilization of the CPU. This statistic includes all tasks that run the CPU
and not only CFS tasks.

But this rq->avg is not the one that is migration aware, right? So why
use this?

We already compensate cpu_capacity for !fair tasks, so I don't see why
we can't use the migration aware one (and kill this one as Yuyang keeps
proposing) and compensate with the capacity factor.
