32 bit systems using 'struct timeval' will break in the year 2038, so we replace the code appropriately.

This patch replaces struct timeval with struct timespec64.

The patch also changes the code to use ktime_get_real_ts64() which returns a 'struct timespec64' instead of do_gettimeofday() which returns a 'struct timeval'
