This can be triggered by building balloon.o while
CONFIG_XEN_BALLOON_MEMORY_HOTPLUG is not set.

I guess commit dfd74a1edfab ("xen/balloon: Fix crash when ballooning on
x86 32 bit PAE") should have put this declaration of
release_memory_resource inside an "#ifdef
CONFIG_XEN_BALLOON_MEMORY_HOTPLUG" preprocessor block.

Thanks,
