I agree.  There should be NO `include' directives, unless we have a
commented-out set of `remove' options in every single GENERIC (...which
would be pointless, of course).

A possible situation would be a Make rule that used cpp, m4, or some other
preprocessor to input both the MD devices, busses, and options, and the MI
config files contaiing all MI devices on particular busses and MI options.
It would then produce includeless `everything' and `support most things'
kernel config files (which could be checked-in like syscall.h).  The
template would then be very easy to customize, and be relatively consistent
across architectures.

Very well; using a preprocessor as above, we could easily define arch
specifics for whether something is supported in the `support most things'
kernel (with the entry _always_ there, whether commented out or not).
