The current DTC does not issue the memory reservation request.
As discussed earlier, it is now relying on the kernel
to do a reservation for the itself.  While I've not seen
it applied yet, I am assuming that Jimi's patch from 14 April
is what is needed here and will be applied.  (Maybe it
just needs a "Signed-off" to make it happen.  Dunno.)
