x86: section mismatch fixes, #1

This patch fixes mismatch warnings in smp_checks() (in arch/x86/kernel/smpboot.c):

WARNING: arch/x86/kernel/built-in.o(.text+0x11922): Section mismatch in reference from the function smp_checks()
to the variable .cpuinit.data:smp_b_stepping
The function smp_checks() references
the variable __cpuinitdata smp_b_stepping.
This is often because smp_checks lacks a __cpuinitdata
annotation or the annotation of smp_b_stepping is wrong.
