But the build of src.c does not depend on CONFIG_SMP.  So when building
with no CONFIG_SMP, we get:

  CC      arch/arm/mach-imx/src.o
arch/arm/mach-imx/src.c: In function ‘imx_enable_cpu’:
arch/arm/mach-imx/src.c:31:2: error: implicit declaration of function ‘cpu_logical_map’
make[2]: *** [arch/arm/mach-imx/src.o] Error 1
make[1]: *** [arch/arm/mach-imx] Error 2
