[PATCH bpf-next v3 0/3] A couple of small refactorings of BPF program call sites

["Toke Høiland-Jørgensen" <toke@redhat.com>]

Stanislav suggested[0] that these small refactorings could be split out from the
XDP queueing RFC series and merged separately. The first change is a small
repacking of struct softnet_data, the others change the BPF call sites to
support full 64-bit values as arguments to bpf_redirect_map() and as the return
value of a BPF program, relying on the fact that BPF registers are always 64-bit
wide to maintain backwards compatibility.

Please see the individual patches for details.

v3:
- In patch 3, don't change types of return values that are copied to
  userspace (which should fix selftest errors on big-endian archs like s390)
- Rebase on bpf-next
- Collect Song's ACKs

v2:
- Rebase on bpf-next (CI failure seems to be unrelated to this series)
- Collect Stanislav's Reviewed-by
