- Use ktime_t to be able to use ktime_ms_delta
which is more efficient than timespec64 based methods.

Changes in v3:
- Use a more efficient way to compute condition for exiting
loop.
- Fix variable naming - all caps is only for macros.
Changes in v2:
- Use ktime_t instead of timespec64 for efficiency reasons.

struct timeval on 32-bit systems will have its tv_sec
value overflow in year 2038 and beyond.
Use a 64 bit value to print time of the coredump in seconds.
ktime_get_real_seconds is chosen here for efficiency reasons.

Changes in v2:

using seconds and nanoseconds directly
- use monotonic time (ktime_get()) since we only care about elapsed
time.
