-tip testing found the following build failure:

 arch/x86/kernel/built-in.o: In function `show_cache_disable':
 intel_cacheinfo.c:(.text+0xbbf2): undefined reference to `k8_northbridges'
 arch/x86/kernel/built-in.o: In function `store_cache_disable':
 intel_cacheinfo.c:(.text+0xbd91): undefined reference to `k8_northbridges'

please send a delta fix patch against the tip/x86/cpu branch:

  http://people.redhat.com/mingo/tip.git/README

which has your patch plus the cleanup applied.
