Yes, you are right. I forgot to check.

There's not really that much to prepare. But it really helps to work
against the right tree to begin with :-)

So here's another one, this time prepared against linus/master, and
fully bisectable by delaying the fixing of the headers which have
external users of their guard-names. Check out the (new) 'for-tip'
branch of

    git://git.kernel.org/pub/scm/linux/kernel/git/vegard/linux-2.6-headers.git

There are still headers left which have no guard at all; that's okay.
If they should be changed, it can be done later, it shouldn't make a
difference for now.

Thanks :-)
