In creating its page tables, the espfix code masks its PGTABLE_PROT
value with the supported mask: __supported_pte_mask. This ensures
that unsupported bits are not set in the final PTE. But, it also
sets _PAGE_GLOBAL which we do not want for PTE.

In creating its page tables, the espfix code masks its PGTABLE_PROT
value with the supported mask: __supported_pte_mask. This ensures
that unsupported bits are not set in the final PTE. But, it also
sets _PAGE_GLOBAL which we do not want for PTE. Use
