ppc64 has its own version of sys_time. It looks pretty scary, touching a whole bunch of variables without any locking or memory ordering. In fact, a recent bugreport has shown it can actually go backwards. Time to remove it and just use the generic sys_time, which is implemented on top of do_gettimeofday.
