Admittedly most of the data in the identify page
as seen by the host is fodder for the sake of
existing userspace utilities.  So I don't really
see any case where pass-through of host->guest
data is meaningful or useful.  The patch just
follows suit here with a similar mockup of this
data for the guest userland.
