From: Mathieu Chouquet-Stringer <mchouque@online.fr>
This patch makes the following code work again:
#ifdef STT_REGISTER
if (info->hdr->e_machine == EM_SPARC ||
info->hdr->e_machine == EM_SPARCV9) {
/* Ignore register directives. */
if (ELF_ST_TYPE(sym->st_info) == STT_REGISTER)
break;
}
#endif
This portion of code is sparc specific and nothing else in modpost.c uses
e_machine meaning cross-compiling for sparc on i386 (or any little endian
machine) is the only way to experience the bug.
Without it, e_machine has the wrong value and modpost then generates a lot
of "*** Warning: \"symbol\" [filename.ko] undefined" messages.
