Modified Files:
        src/sys/arch/i386/include [bouyer-xeni386]: pmap.h pte.h

Log Message:
Update system macros for PAE. Because the L3 page directory has only 4 entries,
and because of the way Xen handles it, it's better to have it has static as
possible. So we claim to have only 2 levels, with level 2 being a
"super" PD of 4 pages. pmap switches will be handled by changing the
L3 entries instead of %cr3. Only the first 3 entries will have to be changed,
the last one mapping KVA space only.
