Ok, agreed on that.

Three of them are comment/doc fixes that I think were explicitly approved for
backport in an earlier review.  I thought Pinski had approved backporting the
dump change (to my surprise - I wasn't asking for it), but I actually had just
misread the email.

I'll leave all of the backporting (including earlier versions) until after the
release.
