We were being a bit too nice and didn't give the guest an invalid instruction
interrupt.

While that works, it's not exactly the fastest thing to do, since now the
guest doesn't know that we're not really implementing that instruction, so it...

with KVM!

Add KVM support for S390x

So let's include support for KVM S390x in qemu!...

S/390 CPU fake emulation

Because Qemu currently requires a TCG target to exist and there are quite some
useful helpers here to lay the groundwork for out KVM target, let's create a

This is required to make tcg happy. The emulation target itself won't work...
