On R4k DECstations the Halt button is wired to the NMI processor input rather than an ordinary interrupt input such as on R3k DECstations. This is possible with a different design of the CPU daughtercard that routes the Halt button line from the baseboard connector. Additionally the interrupt input has been reused for a different purpose on the KN04 and KN05 R4k CPU daughtercards so it is better kept masked. Signed-off-by:
