arm_smmu_s1_cfg (and by extension arm_smmu_domain) owns both a CD table and the CD inserted into that table's non-pasid CD entry. This limits arm_smmu_domain's ability to represent non-pasid domains, where multiple domains need to be inserted into a common CD table. Rather than describing an STE entry (which may have multiple domains installed into it with PASID), a domain should describe a single CD entry instead. This is precisely the role of arm_smmu_ctx_desc. A subsequent commit will also move the CD table outside of arm_smmu_domain.

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.
