[PATCH 04/18] x86 idle: EXPORT_SYMBOL(default_idle,pm_idle) only when APM demands it

From: Len Brown
Date: Sat Apr 02 2011 - 02:23:25 EST


From: Len Brown <len.brown@xxxxxxxxx>

In the long run, we don't want default_idle() or (pm_idle)() to
be exported outside of process.c. Start by not exporting them
to modules, unless the APM build demands it.
