The purpose of __ is to indicate a low-level function which requires
special knowledge to call (usually a lock).  The cpu hotplug code is a
little odd, but way back when, it had cpu_disable() and cpu_die(), so
the arch-specific parts which actually did the work were called
__cpu_disable() and __cpu_die().  The names stuck.

There's nothing special required to call cpu_is_hotpluggable(), so it's
wrong to prepend __.

Sorry for the inconsistency,
Rusty.
