Why do you do this for GUEST_PAGING_LEVELS>= 3 rather than

Xen can run in 32bit PAE mode but the guest in 64bit mode.

But that is what distinguishes GUEST_PAGING_LEVELS from
CONFIG_PAGING_LEVELS - you're allowing a PAE *guest* to use
1Gb mappings, no matter what host it runs on.

Oh, then I mixed those two up. New fixed patch attached.
Thank you for your review.
