A quick grep ...
k7.c:123:void __init amd_mcheck_init(struct cpuinfo_x86 *c)
mce.c:43: amd_mcheck_init(c);
mce.c:48: intel_p5_mcheck_init(c);
mce.c:50: intel_p6_mcheck_init(c);
mce.c:52: intel_p4_mcheck_init(c);
mce.c:57: winchip_mcheck_init(c);
p4.c:209:void __init intel_p4_mcheck_init(struct cpuinfo_x86 *c)
p5.c:30:void __init intel_p5_mcheck_init(struct cpuinfo_x86 *c)

winchip.c:24:void __init winchip_mcheck_init(struct cpuinfo_x86 *c)
The mce.c entries are excluded by "#ifdef CONFIG_X86_MCE". For some reason,
the entire subdirectory has been built but the processor-specific modules
don't have any CONFIG_X86_MCE protection. This one's beyond my skill even to
attempt to fix. I guess I'll turn on machine check exceptions...
