The file drivers/edac/edac_mce_amd.c references a kernel variable that
is not exported for modules.

 ERROR: "per_cpu__cpu_llc_id" [drivers/edac/edac_core.ko] undefined!


The variable in question is located in arch/x86/kernel/smpboot.c

/* Last level cache ID of each logical CPU */
DEFINE_PER_CPU(u16, cpu_llc_id) = BAD_APICID;

and is not exported to modules.

This is from the latest Linus repo. I can supply a config if requested.
