    We could simplify swiotlb initialization after 2.6.36. If we merge my
    patches to expand swiotlb memory dynamically, we could initialize
    swiotlb before any hw IOMMUs (see the commit

    If you can make Xen swiotlb initialized like HW iommu, the IOMMU
    initialization could be cleaner.

    As I wrote, I also want to simplify swiotlb's init memory
    allocation. I'll see what I can do on the whole issue.
