Subject: cpu: fix section mismatch related to cpu_chain
From: Sam Ravnborg <sam@xxxxxxxxxxxx>
Fix following warnings:
WARNING: o-x86_64/kernel/built-in.o(.text+0x36de9): Section mismatch in reference from the function take_cpu_down() to the variable .cpuinit.data:cpu_chain
WARNING: o-x86_64/kernel/built-in.o(.text+0x36e86): Section mismatch in reference from the function _cpu_down() to the variable .cpuinit.data:cpu_chain

WARNING: o-x86_64/kernel/built-in.o(.text+0x36f8f): Section mismatch in reference from the function _cpu_down() to the variable .cpuinit.data:cpu_chain
WARNING: o-x86_64/kernel/built-in.o(.text+0x370aa): Section mismatch in reference from the function unregister_cpu_notifier() to the variable .cpuinit.data:cpu_chain
cpu_chain is used by unregister_cpu_notifier() that is used
by the kvm module. So we can call the unregister_cpu_notifier() long
after init completed.
Drop the __cpuinitdata annotation to avoid freeing cpu_chain.
