====================
Some BPF helper cleanups

This series contains a couple of misc cleanups and improvements
for BPF helpers. For details please see individual patches. We
let this also sit for a few days with Fengguang's kbuild test
robot, and there were no issues seen (besides one false positive,
see last one for details).
