Kernels No Longer Actively Maintained With Ksplice

The following kernels don't receive Ksplice updates, but any Ksplice updates previously issued are still available.

To maintain any of the following kernels on a listed Linux distribution, you need to manually upgrade them by using the yum update or dnf update command, or in the case of Ubuntu, by using the apt command. Kernel updates that don't use Ksplice require system reboots to be effective.

If you're running any of these kernel types on either Oracle Linux 6 or Oracle Linux 7, update to the minimum version of UEK R4.
