Introduce first-stage address translation support. Page table configured by the IOMMU driver will use the highest mode implemented by the hardware, unless not known at the domain allocation time falling back to the CPU’s MMU page mode. This change introduces IOTINVAL.VMA command, required to invalidate any cached IOATC entries after mapping is updated and/or removed from the paging domain. Invalidations for the non-leaf page entries use IOTINVAL for all addresses assigned to the protection domain for hardware not supporting more granular non-leaf page table cache invalidations.

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.
