* x86, 64-bit: PSE no longer a hard requirementJeremy Fitzhardinge2008-07-081-1/+1
| | | | | | | | | | | | | | Because Xen doesn't support PSE mappings in guests, all code which assumed the presence of PSE has been changed to fall back to smaller mappings if necessary. As a result, PSE is optional rather than required (though still used whereever possible).
