This patch is based on Aviv Ben-David (<bd.aviv@gmail.com>)'s patch upstream: "IOMMU: enable intel_iommu map and unmap notifiers" https://lists.gnu.org/archive/html/qemu-devel/2016-11/msg01453.html However I removed/fixed some content, and added my own codes. Instead of translate() every page for iotlb invalidations (which is slower), we walk the pages when needed and notify in a hook function. This patch enables vfio devices for VT-d emulation. And, since we already have vhost DMAR support via device-iotlb, a natural benefit that this patch brings is that vt-d enabled vhost can live even without ATS capability now. Though more tests are needed.
