Thank you, I will take that in mind for the next version.

DXE services are part of UEFI Platform Initialization Specification [1]
Functions used in this patch are described in section 7.2.4, Global
Coherency Domain Services, starting with page 325 (2-41) in version 
1.7A.

Actually, the fact that DXE services are not the part of the main UEFI
spec, was one of the reasons to create the new protocol.
The one remaining problem with it is that it is not supported yet by
the implementation which was the reason for this patch to exist.
