From 8381f6a0c02fdf457d1712cb82f2f0240f2f03cc Mon Sep 17 00:00:00 2001 From: Anna-Maria Gleixner Date: Wed, 13 Jul 2016 17:16:27 +0000 Subject: perf/x86/amd/power: Change hotplug notifier to a symmetric structure 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.
