CD table entries and STE's have the same essential programming sequence, just with different types. Use the new ops indirection to link CD programming to the common writer. In a few more patches all CD writers will call an appropriate make function and then directly call arm_smmu_write_cd_entry(). arm_smmu_write_ctx_desc() will be removed. Until then lightly tweak arm_smmu_write_ctx_desc() to also use the new programmer by using the same logic as right now to build the target CD on the stack, sanitizing it to meet the used rules, and then using the writer. Sanitizing is necessary because the writer expects that the currently programmed CD follows the used rules. Next patches add new make functions and new direct calls to arm_smmu_write_cd_entry() which will require this.

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 reStructuredText 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.
