Daniel stumbled over the bit overlap of the i82498DX external APIC and the TSC deadline timer configuration bit in modern APICs, which is neither documented in the code nor in the current SDM. Maciej provided links to the original i82489DX/486 documentation. See Link. Remove the i82489DX macro maze, use a i82489DX specific define in the apic code and document the overlap in a comment.

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.
