This function may be called from tracing code, since that code needs to read the timer and this often requires calling do_div(), which calls __div64_32(). If this function is instrumented it causes an infinite loop, since emitting a trace record requests the time, which in turn emits a trace record, etc.
Update the prototype to prevent instrumentation code being added.
