I do agree with this -- all changes should be tested by _someone_.
However, I don't think we should categorically reject all patches that
haven't been tested by the author. If someone sees something which
looks wrong, or an opportunity for optimization, not having the board
in question shouldn't stop him from submitting a patch IMO. The board
maintainer (or cpu/arch/subsystem maintainer, depending on the code in
question) may test it himself, or send it to someone else for testing.

I disagree with your requirement that the author and the tester
_always_ has to be the same person. Having done thorough testing,
benchmarking, etc. and providing lots of nice numbers will of course
increase the chances of acceptance, but none of it is an absolute
requirement IMO.

Ok, I don't know who you're talking about, then. Sorry for taking it
personal ;-)
