Interesting. I thought I looked at cris when I made the list and found that
it was still (semi-)regularly updated, so I assumed it was still needed.

(adding CRIS and microblaze maintainers)

Jesper/Mikael: If you are considering to drop the port, I think it
would make sense to do it at the same time as the others, so feel
free to send me a removal pull request for 4.17 that I'll merge with
the other removal patches, or I can offer to remove it myself.

Obviously if your plans have changed in the meantime and you
prefer to keep it for a while longer, just let me know and I'll document
the state in the tag description for the arch removal for future reference.

If we remove cris, it's probably also appropriate to ask the question
about microblaze: Michal, I know your work on microblaze linux has
been winding down over the years as the user base shrinks (just
like for all others above). Should we keep it for a few more years for
the remaining users, or is it time to let go? I would guess we still
have active users on modern kernels, but that's what I thought
about cris as well ;-)
