Christian Borntraeger d1bb69db4c s390x/protvirt: allow to IPL secure guests with -no-reboot 
Right now, -no-reboot prevents secure guests from running. This is
correct from an implementation point of view, as we have modeled the
transition from non-secure to secure as a program directed IPL. From
a user perspective, this is not the behavior of least surprise.

We should implement the IPL into protected mode similar to the
functions that we use for kdump/kexec. In other words, we do not stop
here when -no-reboot is specified on the command line. Like function 0
or function 1, function 10 is not a classic reboot. For example, it
can only be called once. Before calling it a second time, a real
reboot/reset must happen in-between. So function code 10 is more or
less a state transition reset, but not a "standard" reset or reboot.
