Most of the changes are for AMD IOMMU driver. The changes there are bigger than
usual because I did a lot of changes to the data structures storing the
relations between devices, protection domains and iommus. A major change is
that the amd_iommu_pd_table is now gone and replaced by a struct iommu_dev_data
for each device stored in dev->archdata->iommu.
These changes result in a more robust reference counting, especially for
devices with an alias and simplified code in many places.
Also included are some related cleanups which separated the internal function
prototypes to a several header and code movement to get rid of most function
forward declarations. Please pull.

Joerg
