When building with memory hotplug enabled and cpu hotplug disabled, we
end up with the following section mismatch:
WARNING: mm/built-in.o(.text+0x4e58): Section mismatch: reference to
.init.text: (between 'free_area_init_node' and '__build_all_zonelists')
This happens as a result of:
-> free_area_init_node()
-> free_area_init_core()
-> zone_pcp_init() <-- all __meminit up to this point
-> zone_batchsize() <-- marked as __cpuinit
This happens because CONFIG_HOTPLUG_CPU=n sets __cpuinit to __init, but
CONFIG_MEMORY_HOTPLUG=y unsets __meminit.
Changing zone_batchsize() to __init_refok fixes this.
