Except, if you make soft_restart able to return an error, then you really
need machine_restart() to do the same, but that's a cross-arch function.

And what do you do when you hit a soft-watchdog event and it calls
machine_restart(), which then decides to fail?  Or a panic event and
machine_restart() fails?
