These are few nocb related cleanup patches for the next merge window that I am resending. The fourth patch is trivial extraction of duplicate code for canceling deferred wakeups.
I did not hear back about opinions on "Add warning to detect if overload advancement is ever useful" [1] so I will hold off on deleting that code path till the next merge window (for now the patch is just adding a warning). Changes from v1: - Added patch 4 to extract nocb_defer_wakeup_cancel() helper - Add Frederic's review talk to "Remove unnecessary WakeOvfIsDeferred wake path" nocb rcutorture scenarios passed overnight testing on my system.
