Hi Frank,

> I'm trying to find a way to do an MMU off / on transition.

You might want to chat with Per Fransson (CC'd) about this since he
posted something similar a while back:

http://lists.infradead.org/pipermail/linux-arm-kernel/2010-November/030470.html

I still believe we need some code along these lines for kexec and some
instances of CPU hotplug (e.g. on Versatile and RealView platforms).
