Re: [edk2-devel] [PATCH 3/3] StandaloneMmPkg:Remove MpInformation.h

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

Hi Ard,

This patch set has been dropped. Another patch set "Create and consume a new gMpInformationHobGuid2 in UefiCpuPkg." is adopted.
When the Maximum length 64KB is not enough, there might be more than 1 HOB instance of this gMpInformationHobGuid2.
There is no change in  ARM related code in the new patch set.

Thanks,
Dun

Doesn't this break the ARM build?
