Nit: Please avoid introducing double blank lines.
It may be desirable to change Xen's PAT for various reasons. This
requires changes to several _PAGE_* macros as well. Add static
assertions to check that XEN_MSR_PAT is consistent with the _PAGE_*
macros, and that _PAGE_WB is 0 as required by Linux.
