Hi,

this patch series makes the current KVM device passthrough code generic
enough so that other IOMMU implementation can also plug into this code.
It works by factoring the functions Vt-d code exports to KVM into a
generic interface which allows different backends.

This a basic implementation of a generic interface. It can and should be
improved later to support more types of hardware IOMMUs then VT-d and
AMD IOMMU.

Since I have no VT-d hardware available these patches are only compile
tested for now.

Please review, comment and test these patches.

Thanks,

Joerg
