Honestly, such a design principle is pretty broken.  mce_intel.c
contained two completely orthogonal piece of functionality -- CMCI and
thermal -- that really should be in different files (and mce_intel.c
probably should be renamed cmci.c).  Furthermore, using #ifdef for
selecting specific code is considered less clean than using the Makefile
for this purpose.
