Unfortunately, I was not able to come up with anything suitable.
I think your proposal to always define NR_CPUS=1 for architectures without SMP support is a good solution.
After all, if !SMP because the architecture does not support it, I believe it makes sense that NR_CPUS be defined to 1.
Unless NR_CPUS carries with it a hidden meaning about SMP being possible, that is, which would probably be wrong anyway, since we have SMP for this.
