I put a slightly fancier version here last night so that the 0day bot
could chew on it:

https://git.kernel.org/pub/scm/linux/kernel/git/luto/linux.git/commit/?h=x86/fixes&id=b294da548d92320f194172272dda1f734e51013d

want to snarf it up? It's the same thing except that I added Linus'
suggested change, found the offending patch that broke it (hi Linus!)
and added a bit more changelog :)
