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.
