Log message:
Move over to the v1 of Grant Table entries
In spite of comments in the Xen source code encouraging use of v2
entries in the new code, there's no benefit for us to do so at the
moment. While v1 entries support only full page mappings, they're
half the size of their newer counterparts, increasing the number
of available grant table references from 8000 to 16000 within the
same allotment of grant table frames (up to 32).
