On s390, we don't have memory mapped I/O. KVM is virtio only, and even if we would add channel devices we would not require softmmu emulation here.

It means that memory access will aways be kernel memory accesses. IIRC, even with KVM enabled, softmmu accesses are possible in some cases (devices ?).
