c31b5c0ae8
This is a backwards-incompatible binary change, which increases sizeof(cpu_raw_data_t). Specifically, the cpu_raw_data_t::intel_fn4 array is increased from 4 to 8 elements, because on recent Hasells (Crystalwell) there is a Level 4 cache, which should be encoded in CPUID eax=4 ecx=4. However, we were only storing levels for eax=4 for ecx <= 3. Thus the raw data didn't have the relevant info. There will be further changes to this, specifically to store and print the level 4 cache in cpuid_tool.
