I don't really have a strong opinion.  But I would just stick to 1
tree.  It should be easy to see what ofed adds on, just by doing a
diff between the upstream branch and the ofed branch.  And I don't
think that checking out a full linux tree is a big deal -- maybe it
takes a few extra seconds but I don't see any real disadvantage.
