I'm slightly puzzled by the mixture of cpu architectures and fedora
versions between your subject and message body, but ...

Do you mean why not have a non-smp kernel for x86_64? If so probably
because many(most?/all?) EMT64 CPUs support HT or dual core.
Or do you mean why have SMP and non-SMP versions for other CPUs? If so
because various types of locks can be optimized away if not using SMP.
