Ah, right. (There isn't really an equivalent to this on ARM since
we don't have a real NMI equivalent. So any implementation for ARM
qemu would be board dependent since you could wire a watchdog up to
any interrupt.)

Should we try to pick a command name that says what it's supposed to
do rather than how it happens to be implemented on x86 ?
