The more serious problem is what i reported, that your patch 
triggers this build failure:

arch/x86/kernel/built-in.o: In function `store_cache_disable':
intel_cacheinfo.c:(.text+0xd322): undefined reference to `k8_northbridges'
arch/x86/kernel/built-in.o: In function `show_cache_disable':
intel_cacheinfo.c:(.text+0xd52c): undefined reference to `k8_northbridges'

so i've excluded it from tip:master for now. Please resubmit a 
fixed patch.
