This won't work in configs with CONFIG_X86_MCE_INTEL disabled.
You need to define CONFIG_X86_MCE_CENTAUR or so which depends on
CONFIG_CPU_SUP_CENTAUR and CONFIG_X86_MCE_INTEL and which then makes
sure the intel CMCI et al stuff is enabled.

Newer Centaur support CMCI mechnism, which is compatible with INTEL CMCI.
