I fear that to merge them into my tree now will invite merge conflicts
and/or code breakage when something gets merged without regard to these
changes.  As I said last time around, the point to merge these (as newly
updated patches) is once we freeze new platform support just before the
next merge window.

So I'm not merging them until the potential last week prior to the merge
window opening - please keep an eye on Linus' -rc announcements and
send updated patches (against my -devel tree - this is one case where
we're going to have to do it this way) to the patch system at when Linus
indicates that he's released the final -rc.

Thanks.
