Wow, did you really get all of this from that webpage??
Sorry no. I ran the build again ... mmm cross compilers :)
Thanks for chasing this down!
np.
Technically, it could also happen on PPC (APUS), but all APUS support got removed a few months ago. So maybe CONFIG_ZORRO is more appropriate?
Well as it turns out it can happen in a few other plcaes (the same error is visible on sh aswell: http://kisskb.ellerman.id.au/kisskb/buildresult/27769/ ) Below is a new fix. Thoughts?.

Tag ei_local as "__maybe_unused" to keep it around and keep the warnings the original commit is trying to silence ... silenced.
