The ARM folks do this sort of stuff on a regular basis.. Very early on
Doug prepares a topic branch with only the big change, NFS folks pull
it and then pull your work. Then Doug would send the topic branch to
Linus as soon as the merge window opens, then NFS would send theirs.

This is alot less work overall than trying to sequence multiple
patches over multiple releases..
