commit 103a469dc7755fd9e8ccf362f3dd4c55dc761908
Author: Sajan Karumanchi <sajan.karumanchi@amd.com>
Date: Wed Jan 18 18:29:04 2023 +0100
x86: Cache computation for AMD architecture.
All AMD architectures cache details will be computed based on
__cpuid__ `0x8000_001D` and the reference to __cpuid__ `0x8000_0006` will be
zeroed out for future architectures.

commit dcad5c8578130dec7f35fd5b0885304b59f9f543
Author: Sajan Karumanchi <sajan.karumanchi@amd.com>
Date: Tue Aug 1 15:20:55 2023 +0000
x86: Fix for cache computation on AMD legacy cpus.
Some legacy AMD CPUs and hypervisors have the _cpuid_ '0x8000_001D'
set to Zero, thus resulting in zeroed-out computed cache values.
This patch reintroduces the old way of cache computation as a
fail-safe option to handle these exceptions.
Fixed 'level4_cache_size' value through handle_amd().
