Subject[PATCH 17/18] 2.6.40: x86 idle: do not export default_idle() and (pm_idle)()
Date
From: Len Brown <len.brown@intel.com>

With the removal of apm_cpu_idle(), we can now remove
EXPORT_SYMBOL() for both default_idle() and (pm_idle)().

Further, make default_idle() static.
(pm_idle)() is still global b/c it is used by cpu_idle().
