'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.
