From: Arnd Bergmann <arnd@xxxxxxxx>
The newly added function fails to link on nommu kernels, but is also
not needed there:
ld.lld-20: error: undefined symbol: __get_vm_area_node
>>> referenced by execmem.c
>>> mm/execmem.o:(execmem_vmap) in archive vmlinux.a
>>> referenced by execmem.c
>>> mm/execmem.o:(execmem_vmap) in archive vmlinux.a
Fixes: 57bc3834fb6f ("alloc_tag: populate memory for module tags as needed")
