Displays detailed information about the CPU(s) gathered from the
CPUID instruction, and also determines the exact model of CPU(s).
Where /proc/cpuinfo shows features important to a system, cpuid shows
what every feature in each CPU's architecture does.
It is updated and released frequently to stay current with Intel and
AMD information and supports other vendors' chips.

2024-09-12 cpuid.c
- For (0,6),(11,14),0 Intel N-Series, add Twin Lake core name. It can
only be distinguished with MSR IA32_PLATFORM_ID (17h) -- or by brand
name (which would be unreliable if new brandings appear).
- For (synth) decoding of VIA (0,7),(5,11), removed Zhaoxin KaiXian
KX-7000 possibility, based on findings that those likely are rebadged
Intel CPUs instead.
- In decode_uarch_intel(), for Jintide Gen1, used family field to
indicate that they're based on Intel Skylake.
- In decode_uarch_via(), for ZhangJiang CPU's, used family field to to
indicate that they're based on VIA C7. Did not provide a family for
WuDaoKou or LuJiaZui, because it isn't clear how far they have
diverged.
- Changed comments after 743844-012 corrects (0,6),(11,15),5 to be
stepping H0.
- In decode_uarch_hygon(), widened Moksha name to include all of Hygon
family (9,15). Based on Jinke F. patch to perfmon2, which applies the
name to all of fam18h.
- In decode_uarch_hygon(), used family field to indicate that it's based
on AMD Zen.
- Added missing AMD Ryzen numbers: Rembrandt=6000/7000, Mendocino=7000,
Raphael=7000, Phoenix=7000/8000, Granite Ridge=9000.
- Updated synth decoding for (0,6),(10,15) to detect Intel Xeon 6
(Sierra Forest) CPUs.
- For (0,6),(8,15),8, add Xeon Scalable (5th Gen). Some of these have
been rebranded from 4th Gen to 5th Gen: LCC U1.
- Added 0x80000007/edx fast CPPC, mentioned in the PPR for Family 19h
Model 61h, Revision B1.
