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

Allow device drivers and VFIO to get notifications on IOMMU translation
fault, and to handle recoverable faults (PCI PRI). These four patches
are relatively mature since they are required by three different series,
and have been under discussion for a while:

* Nested translation support for SMMUv3 [1].
* vSVA for VT-d [2].
* My generic host SVA implementation.

I reworked patch 4 according to previous discussions, and moved the page
response structure to UAPI. For the other patches I only fixed comments
and whitespaces. Please have a look and see if it works for you.
