[PATCH] cpu hotplug: make cpu_notifier related notifier calls __cpuinit only
Chandra Seetharaman [Tue, 27 Jun 2006 09:54:10 +0000 (02:54 -0700)]
Make notifier_calls associated with cpu_notifier as __cpuinit.

__cpuinit makes sure that the function is init time only unless
CONFIG_HOTPLUG_CPU is defined.
