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