+          Hardware driver for OCTEON's on chip watchdog timer.
+          Enables the watchdog for all cores running Linux. It
+          installs a NMI handler and pokes the watchdog based on an
+          interrupt.  On first expiration of the watchdog, the
+          interrupt handler pokes it.  The second expiration causes an
+          NMI that prints a message. The third expiration causes a
+          global soft reset.
+
+          When userspace has /dev/watchdog open, no poking is done
+          from the first interrupt, it is then only poked when the
+          device is written.
