[edk2-devel] [PATCH 1/5] MdeModulePkg: add MpService2Ppi field in SMM_S3_RESUME_STATE

[duntan]

Add MpService2Ppi field in SMM_S3_RESUME_STATE of
AcpiS3Context.h. It will be used to wakeup AP to do the CPU
initialization during smm s3 boot flow in following patches.
With this field, we can avoid sending InitSipiSipi to wakeup
AP.
