Author: ed Date: Fri Nov 6 07:17:31 2009 New Revision: 198973 URL: http://svn.freebsd.org/changeset/base/198973 Log: Add MAP_ANONYMOUS. Many operating systems also provide MAP_ANONYMOUS. It's not hard to support this ourselves, we'd better add it to make it more likely for applications to work out of the box.
