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

> 5.Remove code to set register table/load mtrr/wakeup AP and relocate ap in
> CpuS3.c.
>
> With this patch set, CpuS3.c in smm CPU driver can be simplified.
