kvm: selftests: ucall: fix exit mmio address guessing

2018-12-21T12:58:46Z

Fix two more bugs in the exit_mmio address guessing. The first bug was that the start and step calculations were wrong since they were dividing the number of address bits instead of the address space. The second other bug was that the guessing algorithm wasn't considering the valid physical and virtual address ranges correctly for an identity map.

kvm: selftests: introduce ucall

2018-10-16T22:26:14Z

Rework the guest exit to userspace code to generalize the concept into what it is, a "hypercall to userspace", and provide two implementations of it: the PortIO version currently used, but only useable by x86, and an MMIO version that other architectures (except s390) can use.
