Subject: [RFC PATCH v2 4/4] arm64: Enable dynamic CPU capacity initialization
Date: Fri, 8 Jan 2016 14:09:32 +0000 [thread overview]
Message-ID: <1452262172-31861-5-git-send-email-juri.lelli@arm.com> (raw)
In-Reply-To: <1452262172-31861-1-git-send-email-juri.lelli@arm.com>
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.
