Hello,
(+Ard)
this patch does not apply (with "master" being at 74f90d38c446).

The context no longer matches here. This context has most recently been
modified by commit be4e0cfbad6b ("MdeModulePkg/VariableSmmRuntimeDxe:
switch to MM communicate 2", 2020-05-12):
$ git show be4e0cfbad6b -- \
MdeModulePkg/Universal/Variable/RuntimeDxe/VariableSmmRuntimeDxe.inf

And, because of the Depex change in that commit
(gEfiSmmCommunicationProtocolGuid -> gEfiMmCommunication2ProtocolGuid),
the last (4th) hunk of the present patch also fails to apply:

See the obsolete depex context above.
Ard had sent a heads-up about this under v2:
[email protected]">http://mid.mail-archive.com/[email protected]
https://edk2.groups.io/g/devel/message/59259
Please rebase this series to "master" and repost it.
(Of course I suggest waiting some more for v3 feedback; for example I
plan to review the v3 ArmVirtPkg and OvmfPkg patches.)
Thanks!
