According to http://www.linuxpps.org/wiki/index.php/LinuxPPS_installation:

| As of kernel 2.6.34 there is no need for patching to get basic LinuxPPS
| support working. You can use kernel.org 2.6.34 directly.

It is enabled by default in wheezy and jessie kernels:

$ grep PPS linux-3.2.46/debian/config/config | grep -v ^#
CONFIG_PPS=m
CONFIG_PPS_CLIENT_LDISC=m
CONFIG_PPS_CLIENT_PARPORT=m

$ grep PPS /boot/config-3.2.0-4-amd64 | grep -v ^#
CONFIG_PPS=m
CONFIG_PPS_CLIENT_LDISC=m
CONFIG_PPS_CLIENT_PARPORT=m

$ grep PPS /boot/config-3.10-2-amd64 | grep -v ^#
CONFIG_PPS=m
CONFIG_PPS_CLIENT_LDISC=m
CONFIG_PPS_CLIENT_PARPORT=m

Therefore, please enable PPS support in ntp by default.

All that is needed is a build dependency on pps-tools so that
/usr/include/sys/timepps.h is installed, which ntp's configure uses to
detect PPS support.

A patch is attached for your convenience (note that it also marks #241548
as closeed, because the Oncore driver is now automatically enabled via
--enable-all-clocks).
