tools/x86/kcpuid: Introduce a complete cpuid bitfields CSV file
For parsing the cpuid bitfields, kcpuid uses an incomplete CSV file with
300+ bitfields.
Use an auto-generated CSV file from the x86-cpuid.org project instead.
It provides complete bitfields coverage: 830+ bitfields, all with proper
descriptions.
The auto-generated file has the following blurb automatically added:
# SPDX-License-Identifier: CC0-1.0
# Generator: x86-cpuid-db v1.0
The generator tag includes the project's workspace "git describe"
version string. It is intended for projects like KernelCI, to aid in
verifying that the auto-generated files have not been tampered with.
The file also has the blurb:
# Auto-generated file.
# Please submit all updates and bugfixes to https://x86-cpuid.org
It's thus kindly requested that the Linux kernel's x86 tree maintainers
enforce sending all updates to x86-cpuid.org's upstream database first,
thus benefiting the whole ecosystem.
