Please do not top post.

I've seen 'yum update' bring in kernels.  Maybe this was on older 
versions of yum like on this old F7 system.  The goal is to be able to 
allow kernel to update but always keep the original version of kernel.  
I don't see any option right now that will allow this behavior.
