The 2.6 Kconfig language allows to set the range for integer questions.
The patch below adds a range line on all architectures that have a
NR_CPUS question except ia64.
The help text on ia64 didn't suggest any values. Could someone tell the
correct values for ia64 (and if it's only a minimum value of 2)?
diffstat output:

It keeps moving. We've announced experimental versions up to 512 CPUs,
I believe. We being SGI, and our SN product, which uses ia64 arch. So
I guess you can put that in.

Thanks for this information.
The patch to use "range" for NR_CPUS on ia64 is below.
