These changes include updates and improvements in the page table code,
in fault handling and they implement iommu=pt mode for AMD-Vi too.
Last but not least there are also some minor cleanups and fixes for
AMD-Vi and GART included in this pull-request. All these changes are
compile-, boot- and load-tested.

I had to do three merge commits for this pull request because the
amd-iommu/passthrough and amd-iommu/pagetable branches touch the same
code in some parts and the octopus merge of these branches failed. I had
to merge these two branches seperatly.
Please consider to pull.
