cpu: fix section mismatch warnings in *cpu_down
Fix following warnings: WARNING: vmlinux.o(.text+0x75c8d): Section mismatch in reference from the function take_cpu_down() to the variable .cpuinit.data:cpu_chain WARNING: vmlinux.o(.text+0x75d2a): Section mismatch in reference from the function _cpu_down() to the variable .cpuinit.data:cpu_chain WARNING: vmlinux.o(.text+0x75d4d): Section mismatch in reference from the function _cpu_down() to the variable .cpuinit.data:cpu_chain WARNING: vmlinux.o(.text+0x75de4): Section mismatch in reference from the function _cpu_down() to the variable .cpuinit.data:cpu_chain WARNING: vmlinux.o(.text+0x75e33): Section mismatch in reference from the function _cpu_down() to the variable .cpuinit.data:cpu_chain cpu_down is only used from code surrounded by HOTPLUG_CPU so any references to __cpuinit is OK. Add a few __ref to tech modpost to ignore the references. This is just papering over the fact that the cpu hotplug code is fragile with respect to use of HOTPLUG_CPU and in many cases rely on __cpuinit to get rid of code when HOTPLUG_CPU is not enabled. For now this is the least invasive change.
