[RFC PATCH v2 4/4] arm64: Enable dynamic CPU capacity initialization

From: Juri Lelli <hidden>
Date: 2016-01-08 14:09:57
Also in: linux-arm-kernel, lkml
Subsystem: arm64 port (aarch64 architecture), the rest · Maintainers: Catalin Marinas, Will Deacon, Linus Torvalds

Define arch_wants_init_cpu_capacity() to return true; so that
cpufreq_init_cpu_capacity() can go ahead and profile CPU capacities
at boot time.
