The commit right after that, but it's not clear whether the screen
blanking problem was part of the same bug or just another bug that was
introduced at about the same time.

    iommu: Introduce new 'struct iommu_device'

    This struct represents one hardware iommu in the iommu core
    code. For now it only has the iommu-ops associated with it,
    but that will be extended soon.

    The register/unregister interface is also added, as well as
    making use of it in the Intel and AMD IOMMU drivers.
