[patch 24/66] perf/x86/amd/power: Change hotplug notifier to a symmetric structure

From: Anna-Maria Gleixner
Date: Mon Jul 11 2016 - 08:44:00 EST


From: Anna-Maria Gleixner <anna-maria@xxxxxxxxxxxxx>

To simplify the hotplug mechanism move the starting callback to
online. There is no functional requirement that the cpumask bit has to
be set in the starting callback.
