*
* 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()"
