I'm not officially a MIPS maintainer but I have donned the hat
unofficially a few times lately, so FWIW I think the Loongson stuff
should go through the MIPS tree, since it so often touches core
architecture code.

Clearly there have been some issues getting MIPS stuff applied recently,
but I think the right approach long-term is to try and improve things
there rather than bypass the MIPS tree altogether.

I believe assigning a co-maintainer would help spread Ralf's load, even
if that primarily means helping review patches (something we can all
help with tbh), and being able to ack patches which touch MIPS but need
to go through other subsystem trees (e.g. I know David Daney was waiting
on acks for the MIPS portions of the Octeon III ethernet driver series).

I'm willing to take on that role if Ralf is okay with it. I'm already
trying to keep track of fixes and spend more time reviewing patches on
the list, but the more who can help out the better.

The question of who applies patches can't be avoided though. It would
clearly suck to have all the review in the world but still end up with
the co-maintainer having to take the reigns at the last minute to get
those important fixes in, and then have no time to apply anything
substantial for the merge window.
