Please fix my git screw up

This is embarrassing ... So I made the mistake of git pull on each branch (5.4/5/6/master) (without --rebase) before pushing a small update tonight. So when I merged each branch the merge commits from my pulls went into each branch when I pushed. Basically I've spent a couple of hours trying to fix the problem with git revert but it's extremely tedious and I seem to have made the problem worse. Can someone with the appropriate karma please delete each of my commits on 5.4, 5.5, 5.6 and master from Feb 18, 2014? It has turned into a nightmare trying to fix this without rewriting history. Sorry -- it won't happen again :/
