Lendacky, Thomas via groups.io 3323359a81 UefiCpuPkg/MpInitLib: Reuse VMSA allocation to avoid unreserved allocation ... https://bugzilla.tianocore.org/show_bug.cgi?id=4353 When parking the APs on exiting from UEFI, a new page allocation is made. This allocation, however, does not end up being marked reserved in the memory map supplied to the OS. To avoid this, re-use the VMSA by clearing the VMSA RMP flag, updating the page contents and re-setting the VMSA RMP flag. Fixes: 06544455d0 ("UefiCpuPkg/MpInitLib: Use SEV-SNP AP Creation ...")
