Subject: [RFC/RFT PATCH v3 0/4] KVM: x86: full virtualization of guest MTRR

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.  Thanks,

Paolo

v1->v2: AMD IOMMUs do have snooping control [Joerg]
	New patch 1

v2->v3: Split __KVM_ARCH_* defines [Alex]
	SVM: correctly map MTRR values to pgprot [Xiao]

Jan Kiszka (1):
  KVM: SVM: Sync g_pat with guest-written PAT value

Paolo Bonzini (3):
  KVM: count number of assigned devices
  KVM: SVM: use NPT page attributes
  KVM: x86: apply guest MTRR virtualization on host reserved pages
