In preparation for allowing the default domain type to be overridden, this patch adds support for IOMMU_DOMAIN_IDENTITY domains to the ARM SMMUv3 driver. An identity domain is created by placing the corresponding stream table entries into "bypass" mode, which allows transactions to flow through the SMMU without any translation.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
