Yes I did.  Sorry about that.

I just did a test merge and there was one file that was completely
removed and one file with had changes a line or two above where my code
changed.  So nothing too difficult to result.

I don't really mind either way.  But keeping them all in one tree makes
them easier to keep track of, and allows me to do things like see if
I can remove EXPORT_SYMBOL(do_exit) as Christoph suggested.
