This patchset adds support for CCW in TCG mode, allowing a s390-ccw machine to boot using the s390-ccw firmware and zipl, and the Linux kernel to access the virtio-ccw devices.
The way to do that is to wire up all the I/O instructions to the KVM functions emulating them. This is the purpose of the last patch of the series. However a few fixes are needed first to make the s390-ccw machine fully functional under TCG.
