I've reviewed an earlier draft of that document.  Although the examples 
in the latest document appear to be geared towards switcher usage, my 
suggestions to the ARM folks was to take into account the CPU hotplug 
scenario instead.  The provided examples remained switcher centric, but 
the API in the published document is now much more generic than it used 
to be.  I think it should cover all usage scenarios now.

If you wish to discuss this further (maybe in a separate thread) I'll be 
glad to discuss this with you.
