'struct timeval' uses a 32-bit seconds representation which will overflow in the year 2038 and beyond. This patch replaces the use of struct timeval with struct timespec64 which uses a 64-bit seconds representation and is y2038 safe. The patch is part of a larger effort to remove all 32-bit timekeeping variables (timeval, time_t and timespec) from the kernel.
