[PATCH] x86-64: make GART PTEs uncacheable
This patches fixes the silent data corruption problems being seen using the GART iommu where 4kB of data where incorrect (seen mostly on Nvidia CK804 systems). This fix, to mark the memory regin the GART PTEs reside on as uncacheable, also brings the code in line with the AGP specification.
