Indeed. With vmlinux, we use the symbol table to identify symbols with a LEP, and we adjust those symbols during load time. However, with kallsyms, we don't have any data around which symbols have a LEP and which don't. So, we can't fixup all the entries globally. - Naveen _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
