32 bit systems using 'struct timeval' will break in the year 2038, so we modify the code appropriately.
This patch replaces the use of struct timeval and do_gettimeofday() with 64 bit ktime_get_seconds() since we only need to find elapsed seconds.
stats_reset_time variable has been converted from a u32 to u64 type to store the 64 bit value returned by ktime_get_seconds().
