Although iommu-dma is a per-architecture chonce, that is currently implemented in a rather haphazard way. Selecting from the arch Kconfig was the original logical approach, but is complicated by having to manage dependencies; conversely, selecting from drivers ends up hiding the architecture dependency *too* well. Instead, let's just have it enable itself automatically when IOMMU API support is enabled for the relevant architectures. It can't get much clearer than that.

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 Restructured Text 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.
