Hello, Here's an initial throw at adding hypercall support to qtest. This aims at making s390 virtio (and soon virtio-ccw) easily testable during refactorings such as Fréderic's. Depending on progress it might also be a route to add qtest support for the individual virtio devices while waiting for a PCI libqos. :-)
qtest.c is being compiled once, so it cannot contain target-specific code. I therefore add stubs qtest_hypercall_supported() and qtest_hypercall(). s390x then overrides them indicating support and implementing it. A dummy test case is appending for verification that things compile and work so far. One bug fix was already posted based on this testing; series is based on it. I have not yet investigated what changes may need to be applied to the API to make this work for sPAPR as well. Looking forward to feedback.
