In the V2 patch set: Added more comments in the new MpInformation.h to document that some fields in this HOB may be invalidated.
Move gMpInformationHobGuid from StandaloneMmPkg to UefiCpuPkg. Previously, the HOB is defined, created and consumed only in StandaloneMmPkg. The HOB contains the number of processors and EFI_PROCESSOR_INFORMATION structure. This is the same as the information that PiSmmCpuDxeSmm uses EfiMpServiceProtocolGuid to get. The incoming plan is to create gMpInformationHobGuid for both StandaloneMm and legacy DXE_SMM in early phase(for example in CpuMpPei). Then PiSmmCpuDxeSmm can consume the hob, which can simplify code logic in PiSmmCpuDxeSmm driver. So move this HOB definition to UefiCpuPkg in this patch series.
