1. Use rpm to install the kernel package(s) that you want, e.g. "rpm
-ivh kernel-xyz kernel-devel-xyz". [Download package for local install
or install directly from the internet, e.g. rpm -ivh url_of_package.]
2. Restart and boot the kernel that you want to keep
3. Remove the kernel, kernel-headers, and kernel-doc, etc. that you do
not want.
4. Use yum to install/upgrade kernel packages.
