Add a loadable test module that validates CXL address translation calculations using parameterized test vectors. The module tests both host-to-device and device-to-host address translations for Modulo and XOR interleave arithmetic. Two types of testing are provided: 1. Parameterized test vectors: Test vectors are passed as module parameters in the format: "dpa pos r_eiw r_eig hb_ways math expected_spa". Round-trip validation is performed: - Translate a DPA and position to a SPA - Verify the result matches expected SPA - Translate that SPA back to a DPA and position - Verify round-trip consistency 2. Internal validation testing: When no test vectors are provided, the module performs validation of the translation functions by checking parameter boundaries and running 10,000 iterations of randomly generated valid parameters to exercise the core calculation functions. The module uses the CXL Driver translation functions through symbols exported exclusively for cxl_translate.

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.
