Author: adrian Date: Sat Sep 6 22:38:32 2014 New Revision: 271213 URL: http://svnweb.freebsd.org/changeset/base/271213 Log: Implement local sfbuf_map and sfbuf_unmap for MIPS32. The pre-rework behaviour was not to keep the cached mappings around after the sfbuf was used but instead to recycle said mappings.
