An SMP kernel only applies to running on more than one CPU. With a normal kernel and single, dual or quad (SMP) you will only get cpu0 file. If you have an SMP kernel and running on a board with more than one CPU, you will get multiple cpu? files. One file for each CPU.
SMP is not the CPU; but a standard way of handling multiple CPUs in the same system.
