This is not a Xen specific issue. On native the value comes from the
BIOS and is a single byte, hence the type. Xen uses the same function.
I don't think it is possible for there to ever be more than 127 entries
in an e820 map so other than potentially wasting a couple of entries in
the tables I don't see a problem.
