Thanks. It should be pretty easy to do (define all 8 affinities for your
CPUs, and assign each one to the watchdog it corresponds to).

Of course, the watchdog driver itself is missing interrupt support, so
you will have to hack that as well. If you have any issue with this
stuff, please give me a shout.

Cheers,
