When a CPU is in enabled wait, it can still receive SIGP calls from other CPUs. Since this requires some special handling in KVM, we should have tests for it. This has already revealed a KVM bug with ecall under PV, which is why this test currently fails there. Some refactoring is done as part of this series to reduce code duplication.
