BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4353 Due to AMD erratum #1467, an SEV-SNP VMSA should not be 2MB aligned. To work around this issue, allocate two pages instead of one. Because of the way that page allocation is implemented, always try to use the second page. If the second page is not 2MB aligned, free the first page and use the second page. If the second page is 2MB aligned, free the second page and use the first page. Freeing in this way reduces holes in the memory map.
