[Xen-devel] [PATCH] xen/mmu: Correct PAT MST setting.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

Jan Beulich spotted that the PAT MSR settings in the Xen public
document that "the first (PAT6) column was wrong across the
board, and the column for PAT7 was missing altogether."

This updates it to be in sync.
