For all I know, v850 has been broken and unmaintained for a few years now,
didn't someone have a patch to remove it entirely?

yup, it's queued for 2.6.27-rc1.

Cris has seen significant updates in 2.6.25 by its maintainer.
It's not a very active port, but skipping updates for one kernel
version is on a completely different scale from doing nothing
at all for over three years as in the v850 case.

I don't currently see any architecture (other than v850) in a
state that justifies removing it entirely.

Also, cris has a tree in linux-next now, so there will be updates in 2.6.27.

Hmm missed that, sorry. It was just last time I looked cris
didn't seem to have any updates for a long time.

It was far longer than that.
