We expclitily didn't want it to make it a linux kernel build dependency.
Mainly out of a desire to use the database for other projects beside the
kernel as well, starting with Xen.

So, the tool have multiple transformers which generates "listings".  One
of these listings is now merged:

    https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/arch/x86/kcpuid/cpuid.csv

The tool also generates Linux kernel C data structures:

    https://gitlab.com/x86-cpuid.org/x86-cpuid-db/-/jobs/7907817537/artifacts/download

We're working on a patch series for the x86 subsystem, where the above
data structures will be integrated in the kernel -- along with cpuid
accessors and a data model.

All geneated files also has tags on top that will allow KernelCI to
verify the integrity of these CSV or C header-file listings:

   "Tagging Conventions for Generated Files"
   https://gitlab.com/x86-cpuid.org/x86-cpuid-db/-/blob/tip/README.rst

(I was going to show this and other things at Plumbers x86 track demo,
 but sadly, BBB screen sharing misbehaved during the talk...  Next time
 I'll have a proper fallback mechanism.)

Thanks,
