These commits don't exist in -tip :-/

Some of these don't even exist as patch titles under different 
sha1's - such as "sched, numa: Comment fixlets".

So I'm really confused about what to pick up. What tree are you 
looking at?

-tip is at:

  git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git

Thanks,
