This was another implementation, an override on machine config side.

The kernel version needs to be agreed by both distro and machine configs
and we have a disagreement here.

What kind of alternatives or different solutions do we have?
Another build variant in AB?

For genericarm64 machine, the current setup is not useful with systemd and old
kernel version. Users must recompile or wait until all fixes to kernel configs
are in the oldest available kernel in tree.
