The basics are now functional and I have
started to
re-implement the grant table code.
After studying both the Mini-OS and Linux implementations some, I don't
understand the difference between using XENMAPSPACE_grant_table vs.
GNTTABOP_setup_table to set up the initial grant table mapping

ce between using XENMAPSPACE_grant_table vs.
GNTTABOP_setup_table to set up the initial grant table mapping for the
guest.
Are these calls just newer and older ways of accomplishing the same thing?
The Linux driver seems to use both in various conditions, whereas Mini-OS
uses the former on ARM and
