Hi,
Since the previsor unified cache model series has already introduced a
new compat property "x-vendor-cpuid-only-v2", it's a chance to once
again consolidate more vendor-specific CPUIDs.
Please provide the link to the patch that introduced
"x-vendor-cpuid-only-v2"
When talking about vendor-specific CPUIDs, there are multiple vendors
for x86, including Intel, AMD, Hygon and Zhaoxin. From the patches, you
are only dealing with Intel specifically. So a basic question is, why
not rename "x-vendor-cpuid-only-v2" to "x-intel-cpuid-only"?
I also checked the CPUID leaves currently supported by Intel & AMD and
found that since the previous "x-vendor-cpuid-only," AMD has already
cleaned up the Intel-specific CPUIDs quite well.
As for Intel, the only cleanup needed is for the "extended function
CPUID" leaves (0x80000000~0x80000008). That's what this series does.
This series is based on:

Thanks and Best Regards,
