[PATCH] time: use do_settimeofday64 internally

[Arnd Bergmann]

do_settimeofday is a wrapper around do_settimeofday64, so
we can simply call that function directly, and kill off the
wrapper once the last user is one.

time: Use do_settimeofday64() internally

do_settimeofday() is a wrapper around do_settimeofday64(), so that function
can be called directly. The wrapper can be removed once the last user is
gone.
