Subject: x86: fix crash on cpu hotplug on pat-incapable machines
From: Avi Kivity <avi@xxxxxxxxxxxx>
pat_disable() is __init, which means it goes away after booting is
complete. Unfortunately it is used by the hotplug code if the machine is
not pat-capable, causing a crash.
Fix by marking pat_disable() as __cpuinit.
