cpufreq_update_policy() is called from two places currently. From a workqueue
handled queued from cpufreq_bp_resume() for boot CPU and from
cpufreq_cpu_callback() whenever a CPU is added.
The first one makes sure that boot CPU is running on the frequency present in
policy->cpu. But we don't really need a call from cpufreq_cpu_callback(),
because we always call cpufreq_driver->init() (which will set policy->cur
correctly) whenever first CPU of any policy is added back. And so every policy
structure is guaranteed to have the right frequency in policy->cur.
