This sort of things really makes it awkward to review the series.

Do you really expect the reviewers to mentally triage what is current
and what is only throwaway code? I want to see patches that are merge
candidates, not patches that are only there to cope with the broken
state of the RMM.

If extra hacks are required to work with the current Franken-RMM, keep
them as a separate series that doesn't pollute what is targeted at
upstream.

It also means that any testing you have done will be invalidated when
the one true RMM shows up...
