A couple of fixes for the AMD IOMMU driver have piled up:
* Some fixes for the reworked IO page-table which caused memory
leaks or did not allow to downgrade mappings under some
conditions.
* Locking fixes to fix a couple of possible races around
accessing 'struct protection_domain'. The races got introduced
when the dma-ops path became lock-less in the fast-path.
