VFIO passthrough spits out thousands of messages

[Graeme Brett Houston BSc]

started qemu as:
sudo qemu-system-sparc64 -device vfio-pci,host=0b:05.0,x-no-mmap=on,bus=pciB

messages received thousands of times:

qemu-system-sparc64: -device vfio-pci,host=0b:05.0,x-no-mmap=on,bus=pciB: iommu has granularity incompatible with target AS
qemu-system-sparc64: -device vfio-pci,host=0b:05.0,x-no-mmap=on,bus=pciB: iommu map to non memory area 4079c000

Is this a regression? Can you please bisect to the first commit where it happened?
