Given that there are a lot of patches already in linux-next from Bill
due to this work, I'm not going to do this for all files right now,
sorry.

But, if you want to use this for the files you maintain and push that
out for 3.8-rc1, that would be great.  I'll be walking the tree after
3.8-rc1 is out to catch the stragglers with a script like this.
