Watchdog is not turned off in kernel panic situation.
In certain systems this might prevent the successful loading
of kdump kernel. The kdump kernel might hit a watchdog reset
while it is booting.

To avoid such scenarios add a panic notifier call back function
which can stop the watchdog. This provision can be enabled by
passing watchdog.stop_on_panic=1 via kernel command-line parameter.

First of all, do we really need a new module parameter for that? Why can't it
be done automatically if kdump is expected?

Sounds like a good idea to me.
