Could we keep the Cc: stable tag itself, since the dependency
information ("Cc: <stable@xxxxxxxxxxxxxxx> # 3.3.x: a1f84a3: sched:
Check for idle") is actually very useful? If we discard that, then we
really should revise the whole stable system, since it would mean that
we are in effect discarding the 'upstream first' rule.
