I would prefer if it was made a separate topic.

I like the patch set (and you can add my Acked-by:) *except* 7/7, and
the reason for that is that it really isn't entry code, it is user space
code.

I also dislike deep directory hierarchies in general, unless it really
be avoided, like boot/ or realmode/.
