Subject: ANDROID: arm: wire cpu-invariant accounting support up to the task scheduler
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d486e9857eca50db1319d8485ac75e2787be3891;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ANDROID: arm: wire cpu-invariant accounting support up to the task scheduler

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.
