These are a few nocb related cleanup patches for the next merge window.
Also Frederic please object to the second patch ("Remove dead callback overload
handling") if you would like, but I think based on our discussion I have
implemented your suggestion, so it should be good.
Changes from v2:
- Dropped patch 2 "Add warning if no rcuog wake up attempt happened during
overload" as it was not needed since we removed the dead CB overload handling.
- Replaced "Add warning to detect if overload advancement is ever useful" with
"Remove dead callback overload handling" per Frederic's feedback - instead of
adding a warning, just remove the dead code path entirely.
nocb rcutorture scenarios passed overnight testing on my system.
