This series calls the dma ops configuration for the devices

The dma_configure_ops for a device is now called during
the device_attach callback just before the probe of the

device/driver_detach path.

I'm assuming this will go via some other tree, maybe the IOMMU tree?
I acked the PCI parts, so let me know if you need anything more from me.
