It's less complex to use rtas_rmo_buf exclusively for userspace.  I'm
against introducing kernel use of rtas_rmo_buf, even at reboot time.  If
we did, it would be proper to add a kernel lock to synchronize access to
it, but then userspace apps have no way to take that lock when
mmap()'ing /dev/mem.

This seems like overkill for a situation we've never actually
encountered, imho.
