Add new IOMMU modes for using iommufd in compatibility mode with VFIO_TYPE1_IOMMU and VFIO_TYPE1v2_IOMMU. In these modes, VFIO selftests will open /dev/iommu and treats it as a container FD (as if it had opened /dev/vfio/vfio) and the kernel translates the container ioctls to iommufd calls transparently.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
