[PATCH v1 0/1] s390x: protvirt: SCLP interpretation

[Pierre Morel]

A new proposition:
I think it would be wise to fork directly from handle_instruction
instead to accept per default all instructions with with secure
instruction interception code.
Just in case future firmware with older QEMU.

How ever I let three dors open.

1) This patch accepts the all B2 instructions, mostly I/O.
Some of the instructions will not work correctly for PV until patched.
This should be fixed, and will be, in a separate patch.

2) The same is true for DIAG instructions.

3) Secure notifications are separated from secure instructions and
normal instructions interception because this case is completely new.
For B2 instructions we do not have to do anything this just informative.
However, one information is of interrest, a notification that
SIGP(STOP) is sent to stop the CPUs and terminate QEMU.
