    Subject[PATCH 0/5] IOMMU: Make IOMMU-API ready for GART-like hardware

    this patch-set adds two new functions the the IOMMU-API:

    * iommu_domain_set_attr()
    * iommu_domain_get_attr()

    These are generic functions to set and change attributes of a domain.
    The plan is to have a set of generic attributes implemented by more than
    one IOMMU driver as well as driver specific ones. As an example for the
    first type this patch-set also implements the DOMAIN_ATTR_GEOMETRY
    attribute. It can be used to query information about the address space
    window that can be remapped by the iommu hardware. With this attribute
    is is very easy to support IOMMUs like GART and friends.

    Any feedback appreciated.
