It looks like this could compile without those config > dependencies. Maybe CONFIG_SMP is there as a kindness to kernel building robots :-) Yes, you can build this for a UP kernel (I just did, and there were no build errors). But why? Nobody is going to take their dual socket server with over a hundred logical processors and run a UP kernel on it. Probably ditto for 64BIT. I didn't try the build without that. But minimum memory on these systems is larger than supported by 32-bit kernels. -Tony
