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.
Joerg
