Subject: cpu: fix section mismatch warning in unregister_cpu_notifier
X-Git-Tag: v2.6.26-rc1~669

cpu: fix section mismatch warning in unregister_cpu_notifier

Fix following warning:
WARNING: vmlinux.o(.text+0x75f4e): Section mismatch in reference from the function unregister_cpu_notifier() to the variable .cpuinit.data:cpu_chain

We know that unregister_cpu_notifier is using HOTPLUG_CPU
stuff - so ignore these references.
Annotating unregister_cpu_notifier had been another option
but this caused far more warnings since not all callers were
annotated __cpuinit.
