Hi, here's the latest version of my patchset introducing virtio-ccw. This has been reworked with the changed kernel interface: qemu will now handle all channel I/O requests (except the I/O interrupt related ones that are handled in-kernel in the kvm case). This avoids duplicating code in qemu and in kvm. There are some misc fixes as well (mainly related to virtio-ccw). Use of mutexes has hopefully been exorcised for now. Unfortuately, patch 2 is now rather large - but I couldn't think of a good way to split it up. I still know of various things that need looking into (memory accesses, for one), but I'd like some feedback about the new interface first.
