Ordinarily I'd expect you to send it to Linus.

I tend to merge important-looking bugfixes in my tree in case
maintainers lose them (happens regularly).  I'll then start spamming
the maintainer with the patch.  If the maintainer remains dead then I
might merge it myself, or I might tag it for -stable backporting and
try again in the next kernel.  

If the maintainer can't be bothered setting up a pull request then he
can just send an acked-by and explicitly ask me to merge it up and
I'll then add it to my next approximately-weekly Linus patchbombing.
