[kvm-unit-tests PATCH v1 0/4] s390x: add tests for SIGP call orders in enabled wait

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.

Nico Boehr (4):
lib: s390x: add cleanup function for external interrupts
s390x: smp: move sigp calls with invalid cpu address to array
s390x: smp: use an array for sigp calls
s390x: smp: add tests for calls in wait state
