This PCD holds the address mask for page table entries when memory encryption is enabled on AMD processors supporting the Secure Encrypted Virtualization (SEV) feature. This module updates the under-4GB page tables configured by the S3-Resume code in UefiCpuPkg/Universal/Acpi/S3Resume2Pei. The mask is saved at module start (ScriptExecute.c), and applied when tables are expanded on-demand by page-faults above 4GB's (SetIdtEntry.c).
