There is only one user of the hardpps function in the kernel, so it makes sense to atomically change it over to using 64-bit timestamps for y2038 safety. In the hardpps implementation, we also need to change the pps_normtime structure, which is similar to struct timespec and also requires a 64-bit seconds portion. This introduces two temporary variables in pps_kc_event() to do the conversion, they will be removed again in the next step, which seemed preferable to having a larger patch changing it all at the same time.
