I suggest putting [3/6] at the first patch as it adds definitions that are used by other patches.

Jian. Some suggestion for your consideration: 0) I suggest add Laszlo to review SMM part, and add Ruiyu to review SMM_MEMORY_ATTRIBUTE_PROTOCOL. 1) Would you please mention what test we have done for this feature? Such as OVMF/realPlatform? IA32/X64? Have you validated NT32? Or try to enable protection? :-) 2) Is that any dependency of this patch? I think there is OPENSSL wrapper reallocate() issue not resolved yet. I suggest we check in all dependent patch at first, then check in this one. 3) If you need submit V4, please separate MdeModulePkg/Include/Protocol/SmmMemoryAttribute.h from 2/6 to be a standalone patch. In general, an interface and an implementation are separated.
