This part of the MTRR patches was dropped by Xiao. Bring SVM on feature parity with VMX, and then do guest MTRR virtualization for both VMX and SVM. The IPAT bit of VMX extended page tables is emulated by mangling the guest PAT value. I do not have any AMD machines that support an IOMMU, so I would like some help testing these patches.
