Re: [edk2-devel] [Patch V3 0/6] Create and consume a new gMpInformationHobGuid2 in UefiCpuPkg.

["duntan" <dun.tan@intel.com>]

Hi Laszlo,

Previously I sent a patch set " Move gMpInformationHobGuid from StandaloneMmPkg to UefiCpuPkg. " and thanks for your review. To solve the issue that the maximum length of one HOB might not be enough when CPU count is 1-2000 or bigger and extend the HOB, we decide to create a new MpInfo2Hob in UefiCpuPkg in this patch set. Do you have any comments about the patch set?

Thanks, 
Dun
