Sounds so yep :)

It's a condition of a customer of us, so I can't change it.

But it happens not often that my part is used. So I thought there is a mechanism to disable or reset the watchdog
because it is a legal pause for it. And there is one "touch_softlockup_watchdog()", that does what I want,
BUT just for the current cpu. And so the watchdog blats from the other cpu.
