We have an ability in CI to supply few additional patches on top bpf/bpf-next
trees, but that's usually done for the cases where we've merged a fix into
one tree, but it's needed in both while bpf->net->linus->net-next->bpf-next
circle is still pending.

Does tip/objtool/core dependency relevant for this set?
Can you rebase the current set on top of bpf-next and send it to the list
just to get CI to run it? We won't be merging it into bpf-next, of course.
I'm mainly interested in seeing all that additional tests passing that
we have in bpf-next.
