Adds usage contribution tracking for group entities. Unlike se->avg.load_avg_contrib, se->avg.utilization_avg_contrib for group entities is the sum of se->avg.utilization_avg_contrib for all entities on the group runqueue. It is _not_ influenced in any way by the task group h_load. Hence it is representing the actual cpu usage of the group, not its intended load contribution which may differ significantly from the utilization on lightly utilized systems. cc: Paul Turner <pjt@google.com> cc: Ben Segall <bsegall@google.com> Signed-off-by: Morten Rasmussen <morten.rasmussen@arm.com> Signed-off-by: Vincent Guittot <vincent.guittot@linaro.org>
