The first patch (which is a re-send) corrects an issue with utilization on SMT platforms. Currently CFS utilization is being roughly doubled on these platforms due to differences in the way PELT and overall max CPU capacity are calculated.
The second patch moves away from the policy of going to fmax during RT task activity, instead using rt_avg as an estimate of RT utilization.
