The kdb code will print the monotonic time by ktime_get_ts(), but

Thus we can use the ktime_get_mono_fast_ns() to get the monotonic
time, which is NMI safe access to clock monotonic. Moreover we can
remove the 'struct timespec', which is not y2038 safe.

I'll add this in today, run some tests and it should be in the merge window.
Thanks,
