I'm sure the OMAP people would be interested in this kind of thing as
well - maybe rather than creating a raft of global functions where the
callers have to be #ifdef'd, we could use the technology which we have
in the kernel such as a notifier list?

That'd mean that VFP and L2 cache could hook themselves onto that list
and get notified about these power down/up events.
