KVM: selftests: Test Hyper-V extended hypercall exit to userspace
Hyper-V extended hypercalls by default exit to userspace. Verify
userspace gets the call, update the result and then verify in guest
correct result is received.
Add KVM_EXIT_HYPERV to list of "known" hypercalls so errors generate
pretty strings.
