Oops, you are right. I updated the tag accordingly, and did a full
compile test over this series, so please pull again:

Applied, thanks. On a side note, I decided to pull the branch, extract
the patches and apply them to my tree with git am, so this won't show up
as a proper merge. This is all still pretty new to me and I'm still in
the process of finding out what works best, so I hope you don't mind.
