Now that we have a system-wide page pool, we can use that for the live

Hi maintainers
This series is targeting net-next, but it's listed as delegate:bpf in
patchwork[0]; is that a mistake? Do I need to do anything more to nudge it
along?
I moved it over to netdev, it would be good next time if there are dependencies
which are in net-next but not yet bpf-next to clearly state them given from this
series the majority touches the bpf test infra code.
This series apparently causes bpf self-tests failures:
https://github.com/kernel-patches/bpf/actions/runs/7929088890/job/21648828278
I'm unsure if that is blocking, or just a CI glitch.
The series LGTM, but I think it would be better if someone from the
ebpf team could also have a look.
The CI was not able to apply the patches, so this looks unrelated :
Cmd('git') failed due to: exit code(128)
cmdline: git am --3way
stdout: 'Applying: net: Register system page pool as an XDP memory model

If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".'
