Paolo Bonzini f0f59d069e KVM x86 MMU changes for 6.7: 
- Clean up code that deals with honoring guest MTRRs when the VM has
    non-coherent DMA and host MTRRs are ignored, i.e. EPT is enabled.
 
  - Zap EPT entries when non-coherent DMA assignment stops/start to prevent
    using stale entries with the wrong memtype.
 
  - Don't ignore guest PAT for CR0.CD=1 && KVM_X86_QUIRK_CD_NW_CLEARED=y, as
    there's zero reason to ignore guest PAT if the effective MTRR memtype is WB.
    This will also allow for future optimizations of handling guest MTRR updates
    for VMs with non-coherent DMA and the quirk enabled.
 
  - Harden the fast page fault path to guard against encountering an invalid
    root when walking SPTEs.
