x86_64 allnoconfig:

arch/x86/kernel/cpu/intel_cacheinfo.c:556: warning: 'free_cache_attributes' defined but not used
arch/x86/kernel/cpu/intel_cacheinfo.c:596: warning: 'detect_cache_attributes' defined but not used

Fixing these revealed another shower of unused functions.  Fixing those
led to an even bigger shower.

Obviously, the code is a mess and needs some thought, understanding and
restructuring so that mere mortals can correctly modify it.

I'll drop the patches.   Please test version 3 a bit better?
