bitkeeper revision 1.1443 (428b3f59xxbCVcbUBrHu1R1TkWcYhg)
Cleaner GDT interface. Xen now reserves the last 2 pages of a full-size
(16 page) GDT. A guest can register a GDT with up to 7k entries. Xen
automatically makes the GDT up to max size with empty page mappings,
and turns page faults in that area to #GP(selector).
