It's the data argument to the function, I highly doubt you can get rid of that I'm afraid. on_each_cpu() is just a thin wrapper on top of smp_call_function() so that the caller doesn't have to care about manually calling on the local CPU. So as long as smp_call_function() has a data argument, on_each_cpu() should carry it as well.
So nope, I don't think that's feasible (or even desired).
