    Subject[PATCH v4 10/10] arm64: wire cpu-invariant accounting support up to the task scheduler
    Date
    Commit 8cd5601c5060 ("sched/fair: Convert arch_scale_cpu_capacity() from
    weak function to #define") changed the wiring which now has to be done
    by associating arch_scale_cpu_capacity with the actual implementation
    provided by the architecture.

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