I've been wanting to do this for a long time, so I'm really glad someone stepped up to do it for me :) I've reviewed the patch and it looks good. I worry that other architectures have strange uses for addresses that might produce larger than 32 bit offsets, especially with CONFIG_KALLSYMS_ALL, but since this is an "opt-in" config option, I guess it's ok.
