2019-04-24vfio-ccw: add handling for async channel instructionsCornelia Huck1-0/+88
Add a region to the vfio-ccw device that can be used to submit asynchronous I/O instructions. ssch continues to be handled by the existing I/O region; the new region handles hsch and csch. Interrupt status continues to be reported through the same channels as for ssch.
