32 bit systems using 'struct timeval' will break in the year 2038, so we replace the code appropriately.
This patch replaces struct timeval and do_gettimeofday() with monotonic ktime_get_ns(). Since we are interested in microseconds portion of the time, we can use NSEC_PER_USEC macro but this would lead to expensive division for a frequently used function. Alternatively a bit shift has been done which performs a division of 1024 instead of 1000 which slightly alters the value returned by this function.
