Please don't send subjectless mails by attaching a commit to a mail,
just use git send-email directly.

Is that all there is to say about these?  Nothing about which platforms
might have it, or what it was tested on or ... ?

This doesn't make sense.  Is not MACH_IS_ATARI set when CONFIG_ATARI
is set?  And even if it isn't then just set 48 for MACH_IS_ATARI and
let the default of 49 below take the ATARI=y and IS_ATARI=n case,
without the need for the ?: operator at all.  On top of that, why
aren't you using the ATARI_ETHERNEC option here for your 48 trigger,
instead of the much higher arch/mach level triggers at all?
