Subject: [PATCH v2 0/4] iommu: Add device fault reporting API

Allow device drivers and VFIO to get notified on IOMMU translation
fault, and handle recoverable faults (PCI PRI). Several series require
this API (Intel VT-d and Arm SMMUv3 nested support, as well as the
generic host SVA implementation).

Changes since v1 [1]:
* Allocate iommu_param earlier, in iommu_probe_device().
* Pass struct iommu_fault to fault handlers, instead of the
  iommu_fault_event wrapper.
* Removed unused iommu_fault_event::iommu_private.
* Removed unnecessary iommu_page_response::addr.
* Added iommu_page_response::version, which would allow to introduce a
  new incompatible iommu_page_response structure (as opposed to just
  adding a flag + field).
