Bad things could happen! How about adding if (!summary_indicators) virtio_ccw_use_airq = 0; /* fall back to classic */ ?...

Hi, next version of the guest exploitation of virtio-ccw adapter interrupts. Changes from the last version: - adapt to latest kvm-next - changed housekeeping for indicator locations: we now use cacheline-sized and aligned areas - minor tweaks Cornelia Huck (2): KVM: s390: virtio-ccw: Handle command rejects. KVM: s390: virtio-ccw adapter interrupt support. arch/s390/include/asm/irq.h

Enhanced virtualization protection technology may require the use of bounce buffers for I/O. While support for this was built into the virtio core, virtio-ccw wasn't changed accordingly. Some background on technology (not part of this series) and the terminology used. * Protected Virtualization (PV): Protected Virtualization guarantees, that non-shared memory of a guest that operates in PV
