I am happy with those as well. And from the look of those these look like
acceptable for stable too. So we (or Bernd) should send them to
stable at kernel.org with a note that this is for .32.y. There is only one thing
that needs to be changed, which is that the patches sent need to have

commit <upstream sha1> upstream

inserted as the first line of the comment instead of the statement in the s-o-b
area (this is actually a Linus requirement as I learned today).
