As David said some of the memory cannot be onlined without further steps
(e.g. when it is standby as David called it) and then I fail to see how
eBPF help in any way.

and also, we can fight till the end of days here trying to come up with
an onlining solution which would work for everyone and eBPF would move
this decision to distro level.

The point is that there is _no_ general onlining solution. This is
basically policy which belongs to the userspace.
