For support and testing purposes it is convenient to have the UP kernel 
available.  Sometimes drivers are broken in SMP, and having the 
equivalent UP kernel readily available makes it easy to identify the 
cause of the problem.

This being said, if you are sure that the SMP kernel is stable for your 
system, nothing stops you from removing the "kernel" while keeping 
"kernel-smp".  All package tools up2date/yum/apt should then offer to 
upgrade only kernel-smp automatically.
