    Subject[PATCH v10 03/11] sched: remove frequency scaling from cpu_capacity
    Date
    Now that arch_scale_cpu_capacity has been introduced to scale the original
    capacity, the arch_scale_freq_capacity is no longer used (it was
    previously used by ARM arch). Remove arch_scale_freq_capacity from the
    computation of cpu_capacity. The frequency invariance will be handled in the
    load tracking and not in the CPU capacity. arch_scale_freq_capacity will be
    revisited for scaling load with the current frequency of the CPUs in a later
    patch.
