It looks like some MAINTAINERS links should maybe be updated for PPS - the
referenced page at http://wiki.enneenne.com/index.php/LinuxPPS_support seems to
be dead. There is http://linuxpps.org/doku.php which points to a new mailing
list location as well, but that seems to have very little activity.
