Hi, the following patches implement support for a virtual channel subsystem in the host (virtio-ccw on the host is handled by user space). Patches 1 and 2 add support for injecting I/O interrupts and (some) machine checks via the already existing mechanisms. The most important parts are those handling interrupt delivery. Patch 3 prepares for in-kernel handling of I/O instructions. Patches 4 and 5 make it possible for kvm to re-use some css-related definitions already used by the s390 common I/O layer. Patch 6 introduces the interface to dynamically enable capabilities already in use on ppc to s390. Patch 7 (the big one) adds in-kernel implementations of most I/O instructions (leaving out some facilities that were too complex and are not currently needed; these can convieniently be marked as not supported). Some operations (which are executed asynchronically on real hardware) are outsourced to user space. This in-kernel channel subsystem support can be enabled by user space via a new capability.
