Sounds like a worthy goal.

I tried applying the patches and it seems they haven't been rebased
since v4.18. My rebases are in
https://git.kernel.org/pub/scm/linux/kernel/git/mattst88/alpha.git/log/?h=for-linus

They seem to work for me, FWIW.

Is your plan to have the patches go through the separate architecture
trees, or go in together? I think I'd at least prefer for another
architecture to take the plunge before alpha.
