/*
 * XXX - this was introduced in SunOS 4.x to distinguish between
 * the old pre-4.x "mmap()", which:
 *
 *	only let you map devices with an "mmap" routine (e.g.,
 *	frame buffers) in;
 *
 *	required you to specify the mapping address;
 *
 *	returned 0 on success and -1 on failure;
 *
 * memory and which, and the 4.x "mmap()" which:
 *
 *	can map plain files;
 *
 *	can be asked to pick where to map the file;
 *
 *	returns the address where it mapped the file on success
 *	and -1 on failure.
 *
 * It's not actually used in source code that calls "mmap()"; the
 * "mmap()" routine adds it for you.
 *
 * It'd be nice to come up with some way of eliminating it from
 * the flags, e.g. reporting calls *without* it as "old_mmap()"
 * and calls with it as "mmap()".
