  - s390_handle_wait(): not sure exactly what this is

Loading a "disabled wait PSW" (waiting for interrupts with no interrupts
enabled) is basically the way for an OS to "panic". (The "special wait
PSW" is for signifying that a cpu has been shut down.) IOW, this is
indeed the "panic" case for s390x.

  - s390 unmanageable_intercept(): again not sure, think this is where
    the guest has gone off the rails and we can't keep running

It's basically "the handling code for an exception immediately leads to
the same exception", the cpu has gone into a loop and can't get out of
it again. Not sure if that should be getting some different handling.
Right. I think having both cases in the same bucket makes sense.
