[edk2-devel] [PATCH v4] UefiCpuPkg: Fix bug in MpInitLib

[Leo Duran]

This patch fixes an issue introduced recently in MpInitLib, where we read
a PlatformId MSR that is not implemented on AMD processors. The patch uses
CPUID signature check to skip reading the PlatformId MSR.

Changes since v3:
Add header file entry for CPUID definitions: Register/Amd/Cpuid.h
