The usage patterns that appear to matter are: (a) An initial mmap, followed by an mmap with MAP_FIXED at the same previous address. (b) shmat with SHM_RND, in which case we get to round the resulting address or return EINVAL. Both of (a) and (b) work today if glibc sets SHMLBA to 4kb. On parisc we simply can't deal with the user selecting an arbitrary address.
