I wonder if we should invert CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE, select the separate address space config for s390, sparc64, non-coldfire m68k and mips with EVA and then just have one single access_ok for overlapping address space (as added by Arnd) and non-overlapping ones (always return true).
