Currently, building code which uses the API guarded by the IOMMU_IOVA will fail to link if IOMMU_IOVA is not enabled. Often this code will be using the API provided by the IOMMU_API Kconfig symbol, but support for this can be optional, with code falling back to contiguous memory. This commit implements dummy functions for the IOVA API so that it can be compiled out. With both IOMMU_API and IOMMU_IOVA optional, code can now be built with or without support for IOMMU without having to resort to #ifdefs in the user code.

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.
