I'll build some more kernels tonight and file a bug report with specific
details in a few hours.

Ok, I accept this. I won't pursue this line any further.

I'd like to get back to the original point of my CONFIG_SMP patch,
which removes the SMP and SMP_PROF definition lines from the top-level
Makefile and converts them into ordinary configuration options.
Note that this does not affect generated code for either the non-SMP
or the SMP case, and is unrelated to the discussion we've had about
having SMP-specific code in the header files.

I'd appreciate it if some more people would look at:

and tell me: (1) if you think *this patch* is a good idea, and
(2) if it works on your system.
