[PATCH v2 27/29] x86/cacheinfo: Relocate leaf 0x4 cache_type mapping
Posted by Ahmed S. Darwish 9 months ago
The cache_type_map[] array is used to map Intel leaf 0x4 cache_type
values to their corresponding types at <linux/cacheinfo.h>.

Move that array's definition after the actual CPUID leaf 0x4 structures,
instead of having it in the middle of AMD leaf 0x4 emulation code.
