init_numa_memory() is annotated __init and not used by any module, thus don't export it. Remove not needed EXPORT_SYMBOL for init_numa_memory() to fix the following section mismatch warning: CHK include/generated/compile.h UPD include/generated/compile.h CC init/version.o AR init/built-in.a LD vmlinux.o MODPOST vmlinux.symvers WARNING: modpost: vmlinux.o(___ksymtab+prom_init_numa_memory+0x0): Section mismatch in reference from the variable __ksymtab_prom_init_numa_memory to the function .init.text:prom_init_numa_memory() The symbol prom_init_numa_memory is exported and annotated __init Fix this by removing the __init annotation of prom_init_numa_memory or drop the export.
