Update kcpuid's CSV file to version 2.3, as generated by x86-cpuid-db. Summary of the v2.3 changes: * Per H. Peter Anvin's feedback, leaf 0x3 is not unique to Transmeta as the CSV file earlier claimed. Since leaf 0x3's format differs between Intel and Transmeta, and the project does not yet support having the same CPUID bitfield with varying interpretations across vendors, leaf 0x3 is removed for now. Given that Intel discontinued support for PSN from Pentium 4 onward, and Linux force disables it on early boot for privacy concerns, this should have minimal impact. * Leaf 0x80000021: Make bitfield IDs and descriptions coherent with each other. Remove "_support" from bitfield IDs, as no other leaf has such convention. Reported-by: "H. Peter Anvin" <hpa@zytor.com> Signed-off-by: Ahmed S.

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.
