Which just means that we should never export weak symbols. So instead of hacking around this introduce a symbol that indicates that the architecture impements phys_to_target_node, and don't defined it at all in common code for that case. > --- a/mm/memory_hotplug.c > +++ b/mm/memory_hotplug.c > @@ -365,9 +365,14 @@ int __weak phys_to_target_node(u64 start) > start); > return 0; > } > + > +/* If the arch did not export a strong symbol, export the weak one. */ > +#ifndef CONFIG_NUMA_KEEP_MEMINFO > EXPORT_SYMBOL_GPL(phys_to_target_node); > #endif > > +#endif i.e. move the ifdef to include the actual phys_to_target_node definition, and remove the __weak from it here. _______________________________________________ Linux-nvdimm mailing list -- linux-nvdimm@lists.01.org To unsubscribe send an email to linux-nvdimm-le...@lists.01.org
