Hi Ingo,

(again with fixed commit messages, the code has not changed so I didn't
 repost everything to the mailing lists)

The updates contain two major enhancements. First one is support for
suspend/resume with iommu enabled. The second one is an extended
allocator for DMA adresses. The new allocator grows the DMA address
space in a dma_ops domain dynamically from a 128MB default size to a
maximum of 4GB as required.
Some fixes are also included. Another new feature is the introduction of
CONFIG_IOMMU_STRESS. This feature is indended for randconfig based iommu
code testing. For AMD IOMMU it disables some optimizations to
stress-test the code. Please pull.
