arch/powerpc/mm/slice.c:73:12: error: comparison is always true due to limited range of data type [-Werror=type-limits]
  if (start < SLICE_LOW_TOP) {
            ^
arch/powerpc/mm/slice.c:81:20: error: comparison is always false due to limited range of data type [-Werror=type-limits]
  if ((start + len) > SLICE_LOW_TOP) {
