Wire up disabled wait a panicked event on s390
On s390 the disabled wait state indicates a state of attention.
For example Linux uses that state after a panic. Lets
put the system into panicked state.
An alternative implementation would be to state
disabled-wait <address> instead of pause in the action field.
(e.g. z/OS, z/VM and other classic OSes use the address of the
disabled wait to indicate an error code).
