Agree that the order adjustment can make the patch set clearer. Will modify the commits in next version patch set.

I stronger recommend re-ordering the patches as below so as to combine all related sub-patches together, then we can more easy understand what we are target to resolving: 1) S3 MTRRs operation 2) AP page table unavailiable issue fix. 3) S3 ApHltLoopCode Operation 3) Register table cleanup 1) S3 MTRRs operation: > MdeModulePkg: Add gEdkiiS3MtrrSettingGuid > OvmfPkg: Save MTRR by lockbox in CpuS3DataDxe > UefiCpuPkg: Add locbox lib instance in DSC > UefiCpuPkg: Save MTRR by lockbox in CpuS3DataDxe > UefiCpuPkg: LoadMtrrData for all cpu in S3Resume > UefiCpuPkg: Remove code to load mtrr setting 2) AP page table unavailiable issue fix: > UefiCpuPkg: Disable PG in IA32 ApLoopCode 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: > UefiCpuPkg:Set PcdCpuFeaturesInitOnS3Resume to TRUE > UefiCpuPkg: Remove code to set register table > UefiCpuPkg: Remove GetAcpiCpuData() in CpuS3.c 2. Update all intel copyright year. 3. Add all reviewer in the 00 patch. 4. Add PR in the 00 patch (if have).
