Thanks for the comments. How about change the commits order to be like:
1) S3 MTRRs operation: 2) AP page table unavailiable issue fix: 3) S3 ApHltLoopCode Operation: > UefiCpuPkg:Abstract some DxeMpLib code to function > UefiCpuPkg:Move some code in DxeMpLib to common place > UefiCpuPkg: Install gEdkiiEndOfS3ResumeGuid in S3Resume > UefiCpuPkg:Relocate AP to new safe buffer in PeiMpLib > UefiCpuPkg:Remove code to handle APIC setting and Interrupt > UefiCpuPkg:Rremove code to wakeup AP and relocate ap > UefiCpuPkg: Remove the duplicated mpservice locate > MdeModulePkg: remove MpService2Ppi field in SMM_S3_RESUME_STATE 4) Register table cleanup: Then the patch to remove the assignment for MpService2Ppi will be after the patch to remove the MpService2Ppi field consumption. Also I'll change the title of "UefiCpuPkg: Remove the duplicated mpservice locate" to "UefiCpuPkg: Remove unneeded MpService2Ppi assignment" to make it look clearer.

How about you keep the "SmmS3ResumeState->MpService2Ppi = 0" there and remove that assignment and the field together in this patch?

Currently, in CpuS3.c of smm cpu driver, BSP doesn't need to wakeup AP anymore. The initialization for AP will be done in S3Resume.c before transfer to CpuS3.c of smm cpu driver. So we can remove the MpService2Ppi field in SMM_S3_RESUME_STATE.
