I think it can be simplified a bit more. If you move the definition of RANGE_END_CPUS up to before RANGE_BEGIN_CPUS, you can then make the RANGE_BEGIN_CPUS just be something like default 1 if !SMP default RANGE_END_CPUS if MAXSMP default 2 which makes a whole lot more sense. and if you split that RANGE_END_CPUS so that the x86-32 and x86-64 cases are separate, that makes *those* more understandable. It also makes sense to separate since X86_BIGSMP is 32-bit only. But yes, this looks like it's in the right direction, where we can make each step be fairly obvious, instead of the current NR_CPUS mess that is entirely impossible to parse for mere humans. Linus
