Following 3 patches still require the Reviewed-by from package maintainers of MdeModulePkg and OvmfPkg. MdeModulePkg: Add gEdkiiS3MtrrSettingGuid OvmfPkg: Save MTRR by lockbox in CpuS3DataDxe MdeModulePkg:Remove MpService2Ppi field in SMM_S3_RESUME_STATE
The patch set is a good move to simplify the X86 CPU SMM driver by removing most of S3 related logics. I hope it can be merged next week when the stable tag freeze ends in the end of this week.
