Is it correct? It means that memory access will aways be kernel memory
accesses. IIRC, even with KVM enabled, softmmu accesses are possible in
some cases (devices ?).
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. S390 does'nt have pci, usb or alike.
