Well, my linux-next branch is not to guaranteed to be stable, just like the
entire linux-next tree.

Once the patch stops making trouble, I'll move it into my for-linus branch,
which _is_ guaranteed not to be rebased (in fact it's never rebased).

I haven't done it yet exactly because of these build problems.  Please wait
for a couple of days more for things to settle down.

Rafael
