Re: [PATCH v15 0/8] Adds AmdSmmCpuFeaturesLib and MmSaveStateLib

["Ni, Ray" <ray.ni@intel.com>]

Thanks for reposting.
I will merge it today through this PR: https://github.com/tianocore/edk2/pull/4599

I tried to use your PR but there is a merge-commit there that failed in CI PatchCheck step.

Thanks,
Ray

> Backward-compatibility changes:
>   This patch series removes the SmmCpuFeaturesReadSaveStateRegister
>   and SmmCpuFeaturesWriteSaveStateRegister interface/function.
>   SmmReadSaveState() and SmmWriteSaveState() now directly invokes
> MmSaveStateLib
>   routines to save/restore registers.
