In V3 patch set: 1.Add a new patch 'Remove code that apply AddressEncMask to non-leaf entry'. This patch is to avoid apply AddressEncMask to non-leaf entry when split smm page table. 2.Add two new patches to clear CR0.WP before modify smm page table when ReadyToLock. This is because FvbServicesSmm driver may set a part of smm page table memory as RO before ReadyToLock.
With these three patches, this patch set successfully boots an SEV guest with SMM enabled.
