RH7.3 manpage is quiet old, btw.
Linux manpages-1.54 (Dec 30 2002):
The (Linux-specific) SHM_REMAP flag may be asserted in shmflg to indi- cate that the mapping of the segment should replace any existing map- ping in the range starting at shmaddr and continuing for the size of the segment. (Normally an EINVAL error would result if a mapping already exists in this address range.) In this case, shmaddr must not be NULL.
