lkml has turned into a posting-only mailing list.  I've stopped reading
it years ago; the volume is so insane that I only use it to occasionally
to follow references from other sources.  So don't be surprised if you
don't get an answer.  Linus does not read lkml either.

I suppose we should give it a sane definition.  Not sure what would be
useful, if it should be like an ASCII string with the processor type or
more corse grained like just "mips32r2", should ASEs be mentioned ...
