It's OK because it is called only on BP.

But I think this could be called on hot-plugged AP.
Should be __cpuinit ?

void __cpuinit mcheck_cpu_init(struct cpuinfo_x86 *c)
-> static void __mcheck_cpu_init_vendor(struct cpuinfo_x86 *c)
-> void mce_intel_feature_init(struct cpuinfo_x86 *c)
-> void intel_init_thermal(struct cpuinfo_x86 *c)

Thanks,
