Which just gets another mismatch warning here:

WARNING: arch/powerpc/kernel/built-in.o(.text+0x23cc4): Section mismatch in reference from the function .start_secondary() to the function .devinit.text:.smp_store_cpu_info()
The function .start_secondary() references
the function __devinit .smp_store_cpu_info().
This is often because .start_secondary lacks a __devinit 
annotation or the annotation of .smp_store_cpu_info is wrong.

Isn't there a better way to address this?  It doesn't seem right to
increase the kernel's memory usage to get rid of a modpost warning.
