[qemu-s390x] [PATCH RFC 0/2] s390x: support zpci in tcg

[Cornelia Huck]

This patch set (available at git://github.com/cohuck/qemu pci-tcg)
wires up zpci under tcg. A guest started with

qemu-system-s390x -M s390-ccw-virtio,accel=tcg -cpu qemu,zpci=on -device 
virtio-net-pci (...)

and a 4.15 kernel in the guest (needed because the requirement for ais
was dropped with

    s390/pci: do not require AIS facility

and we don't have a working ais with tcg yet), I get sensible output
out of lspci.

RFC because I'm not sure that I put up the tcg wires in the best way.
