Hm, the x86/cpu topic is marked broken and blocked by another AMD 
patch from Mark Langsdorf:

 45ca863: x86, cpu: conform L3 Cache Index Disable to Linux standards

We cannot queue up new patches there before this one is fixed. I've 
attached below my last bugreport about it.

i'm still getting this build failure:

 arch/x86/mm/built-in.o:(.bss+0x3640): multiple definition of `k8_northbridges'

i've reported this build failure before. I've excluded this commit 
from tip:master for now.
