When a DMA domain is attached to a device, it needs to allocate a domain ID from its IOMMU. Currently, the domain ID information is stored in two static arrays embedded in the domain structure. This can lead to memory waste when the driver is running on a small platform. This optimizes these static arrays by replacing them with an xarray and consuming memory on demand.

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.
