This series is supposed to accelerate IOMMU operations in real and virtual mode in the host kernel for the KVM guest. The first user is VFIO however this series does not contain any VFIO related code as the connection between VFIO and the new handlers is to be made in QEMU via ioctl to the KVM fd. Although the series compiles, it does not make sense without VFIO patches which are posted separately. The "iommu: Add a function to find an iommu group by id" patch has already gone to linux-next (from iommu tree) but it is not in upstream yet so I am including it here for the reference.
