pulled into tip/x86/header-guards, thanks Vegard.

One small request: in the future, could you use git-request-pull to 
generate pull requests?

That way the full URI is included (otherwise it's easy to forget to add 
the 'for-tip' branch to the pull i do, etc.). Something like:

 git-request-pull linus/master \
  git://git.kernel.org/pub/scm/linux/kernel/git/vegard/linux-2.6-headers.git \
   for-tip

should do the trick. Thanks,

	Ingo
