The original intent here was to track unweighted runqueue load with less resolution so we could use the least-recently-disturbed runqueue to choose between 'closely related' load levels. However, after experimenting with the resolution it turns out that the following algorithm is highly beneficial for mobile workloads. In hmp_domain_min_load: * If any CPU is zero, the overall load is zero * If no CPUs are idle, the domain is 'fully loaded' Additionally, the time since last migration count is used to discriminate between idle CPUs.
