Another good reason for an option turning these things on by default is
that it makes debugging *so* much easier when the vmlinux matches what's
actually running!

So yes, that's definitely something we should look at in the long-term,
but we still need the live patching for distro kernels that will assumedly
want a single Image covering ARMv8+ for a while.
