    Subject[Patch v4 4/6] sched/fair: update cpu_capcity to reflect thermal pressure
    Date
    cpu_capacity relflects the maximum available capacity of a cpu. Thermal
    pressure on a cpu means this maximum available capacity is reduced. This
    patch reduces the average thermal pressure for a cpu from its maximum
    available capacity so that cpu_capacity reflects the actual
    available capacity.
