well, I was grepping for all the places where c->x86_cache_size
and c->x86_tlbsize are being used and have missed the location
arch/x86/kernel/cpu/intel_cacheinfo.c:amd_cpuid4() where
current_cpu_data.x86_cache_size is being read so we can't make it
dependent on PROC_FS.

Sorry for misleading you, here's a corrected version:

Subject: [PATCH] x86, cpu: mv display_cacheinfo -> cpu_detect_cache_sizes

display_cacheinfo() doesn't display anything anymore and it is used to
detect CPU cache sizes. Rename it accordingly.
