    Subject[PATCH v2 05/10] arm: wire frequency-invariant accounting support up to the task scheduler
    Date
    Commit dfbca41f3479 ("sched: Optimize freq invariant accounting")
    changed the wiring which now has to be done by associating
    arch_scale_freq_capacity with the actual implementation provided
    by the architecture.

    Define arch_scale_freq_capacity to use the arch_topology "driver"
    function topology_get_freq_scale() for the task scheduler's
    frequency-invariant accounting instead of the default
    arch_scale_freq_capacity() in kernel/sched/sched.h.
