Hi Tom, This patch set is to change PiSmmCpuDxeSmm code to use CpuPageTableLib to create and update SMM page table. The Pcd PcdPteMemoryEncryptionAddressOrMask is also used in PiSmmCpuDxeSmm code and the whole range covered by page table is mapped encrypted, which is different from the situation in DxeIpl module. So could you also help do a test to make sure the AMD SEV feature still works good in SMM with this patch set? Here is the code branch in my fork repo: https://github.com/td36/edk2/commits/SmmPageTable_V2
