sched, cpuset: Drop __cpuexit from cpu hotplug callbacks
Tejun Heo [Mon, 21 Jun 2010 21:53:31 +0000 (23:53 +0200)]
Commit 3a101d05 (sched: adjust when cpu_active and cpuset
configurations are updated during cpu on/offlining) added
hotplug notifiers marked with __cpuexit; however, ia64 drops
text in __cpuexit during link unlike x86.

This means that functions which are referenced during init but used
only for cpu hot unplugging afterwards shouldn't be marked with
__cpuexit. Drop __cpuexit from those functions.
