Some of the syscall helper functions (do_utimes, poll_select_set_timeout, core_sys_select) have changed over the past year or two to use 'timespec64' pointers rather than 'timespec'. This was fine on alpha, since 64-bit architectures treat the two as the same type.
However, I'd like to change that behavior and make 'timespec64' a proper type of its own even on 64-bit architectures, and that will introduce harmless type mismatch warnings here.
Also, I'm trying to kill off the do_gettimeofday() helper in favor of ktime_get() and related interfaces throughout the kernel.

But this syscall is supposed to use the realtime clock, no? It seems like the correct substitute here is getnstimeofday64() (as the kernel- doc comment for do_gettimeofday() *almost* says).
