There's only one watchdog device, so there's only one interrupt. I don't know which CPU will get the interrupt, but the watchdog is not a per-CPU device.
Plus, that one interrupt is not shared, and the driver returns IRQ_HANDLED even if the bit is not set. So _something_ is definitely wrong. Either the interrupt is shared, then it needs to be requested as shared and the handler should only return IRQ_HANDLED if it actually handles the interrupt. Or it is not shared and the handler should always handle it.
