This adds an irq counter for the watchdog soft-NMI. This interrupt only fires when interrupts are soft-disabled, so it will not increment much even when the watchdog is running. However it's useful for debugging and sanity checking. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
