[PATCH] kernel/cpu.c: section mismatch warning fix

[Rakib Mullick]

Impact: small kernel .text reduction in certain configs, and fix warning

This warning:

  LD      kernel/built-in.o
 WARNING: kernel/built-in.o(.text+0xb7c8): Section mismatch in
 reference from the function notify_cpu_starting() to the variable
 .cpuinit.data:cpu_chain
 The function notify_cpu_starting() references
 the variable __cpuinitdata cpu_chain.
 This is often because notify_cpu_starting lacks a __cpuinitdata
 annotation or the annotation of cpu_chain is wrong.

Points out the fact that notify_cpu_starting() is only called
from __cpuinit sequences and itself uses a __cpuinitdata structure.

This patch fixes the above section mismatch warning.
