I think you missed the location in which ffdc_time is initially
assigned, and wher it gets compared to the current time:
struct timeval tv;
ha->last_ffdc = tv.tv_sec;
This needs to be changed to timespec64 to actually avoid the
overflow problem. I think this one should also use monotonic time,
i.e. ktime_get_ts64 rather than getnstimeofday64.
