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

Thanks,
Dun

My comments as below:
1. 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).


Thanks,
Jiaxin
