It's a bit different. The kernel basically does not see msi routes for
s390 pci at all, as qemu already transforms the msi route into an
adapter route before registering it (see kvm_arch_fixup_msi_route() in
qemu's target-s390x/kvm.c). So, in the end, all s390 kernels end up
using adapter routes, and none of them are duplicate (just one irqchip).
Going back to Paolo's original question, I think changing the check
to !KVM_IRQ_ROUTING_IRQCHIP makes sense, if I understand the code
correctly....
