Andrew Morton would take it to his -mm tree.
This, IMO, seems to be the best solution to circumvent unresponsive/uncaring
maintainers.

No, every single patch has to be 'bisectable' meaning that when you bisect
you should be able to build every single patch as is.

Maybe once more, if they don't reply, send it to Andrew Morton as well
and CC a few people who know your work is good so that they can ACK it.

Oh and maybe you could add an __attribute__((deprecated)) to it, but
I am not sure that's possible and/or correct.
