[RFC PATCH v1 0/2] Improvements to SIGP handling [QEMU]

I'm cleaning up some of the SIGP code in KVM and QEMU,
and would like to propose the following changes.

Patch 1 should be less concerning than its KVM counterpart,
since the CZAM bit in question is already present in QEMU.

Patch 2 provides some handshaking with KVM. Since QEMU
injects a Stop IRQ for a couple of the SIGP orders, we
can provide the flags associated with it, to provide some
direction for how KVM should process it.

While this has no dependency on the KVM code, the KVM series
that I'm working on in parallel is here:


Eric Farman (2):
  s390x: sigp: Force Set Architecture to return Invalid Parameter
  s390x/kvm: Pass SIGP Stop flags

 target/s390x/kvm/kvm.c |  4 ++++
