There is of course the problem that we track rq util_avg as a straight
sum of entity util_avg, such that if you migrate/

The current implementation of load tracking invariance scales the
contribution with current frequency and uarch performance (only for
utilization) of the CPU. One main result of this formula is that the
figures are capped by current capacity of CPU. Another one is that the
load_avg is not invariant
