Please see the thread [edk2] [patch] UefiCpuPkg/MpInitLib: Fix VS2012 build failure http://mid.mail-archive.com/20180719045059.55868-1-dandan.bi@intel.com I think when Liming commented on your v1, he was unaware of Dandan's patch. And, I'm seeing your v1+v2 just now, at the same time. Sorry about the inconvenience!
