Revert broken "statement with no effect" warning fix
It may shut up gcc, but it also incorrectly changes the semantics of the smp_call_function() helpers. You can fix the warning other ways if you are interested (create another inline function that takes no arguments and returns zero), but preferably gcc just shouldn't complain about unused return values from statement expressions in the first place.
