Hm. This is a guest thing or? So you basically say, it is OK to do
this, because you know that the guest is gonna be Linux and that it
the channel program is intended to use prefetch -- but the ORB supplied
by the guest that designates the channel program happens to state the
opposite.
Or am I missing something?
