Hi Li,
Maybe I forget to attach it. The cover letter of that CpuLib patch set attached.
Regards,
Abner

Hi Abner,
You pointed out that you attached a patch to your last email, but I didn't find it, do you forgot to put it? In the current EDK II code repo, I can not find the patch which you mentioned.

Recently there is a work to migrate UefiCpuLib to CpuLib (patch attached), you may want to sync up your changes with that patch set. RISC-V will do the same work later.
