I don't follow.  The FMR implementation will always use the IOVA
passed in by the consumer, so a ULP can always map whatever page sets
it wants at whatever IOVA it wants (subject to alignment restrictions,
of course).  So there's no point in making the IOVA be an output
parameter from the FMR pool implementation, since the IOVA from the
consumer will never be changed.
