Again, this is hard to read and contains too much useless information,

  struct timespec is not Y2038 safe on 32 bit machines and needs to be
  replaced with struct timespec64.

  do_sys_settimeofday() is a wrapper around do_sys_settimeofday64().

  Convert all call sites to use do_sys_seetimeofday64() and remove it.

Please use the ordering I pointed out in the other mail.
