Pull IOMMU fixes from Joerg Roedel:
 "The fixes include:

   - fix a crash in the VT-d driver when devices with a driver attached
     are hot-unplugged

   - fix a AMD IOMMU driver crash with device assignment of 32 bit PCI
     devices to KVM guests

   - fix for a copy&paste error in generic IOMMU code.  Now the right
     function pointer is checked before calling"
