| | | | | | | | of the recent WARNS commits. The idea is: 1) FreeBSD id tags should follow vendor tags. 2) Vendor tags should not be compiled (though copyrights probably should). 3) There should be no blank line between including cdefs and __FBSDIF.

| | | | | | | | | | | | - Use MAP_FAILED instead of the constant -1 to indicate failure (required by POSIX). - Removed flag arguments of '0' (required by POSIX). - Fixed code which expected an error return of 0. - Fixed code which thought any address with the high bit set was an error. - Check for failure where no checks were present.
