I really don't see what these giant backports bring us.  If people
want all the changes they'd just be better off on a modern kernel
rather than these frankenkernels.  The automatic backporting is
gettind way out of hand.  If the MD maintainers want
9674f54e41ff, maybe they can send a tailor made backport?
