You still need this:
struct archdata {
const struct exception_table_entry *dbe_table_start;
const struct exception_table_entry *dbe_table_end;
};
In init_module:
#ifdef __mips__
{
extern const struct exception_table_entry __start___dbe_table[];
extern const struct exception_table_entry __stop___dbe_table[];
static struct archdata archdata_mips =
{ __start___dbe_table, __end___dbe_table };
kernel_module.archdata_start = (char *)&archdata_mips;
kernel_module.archdata_end = kernel_module.archdata_start +
sizeof(archdata_mips);
}
#endif
I really need to add an arch specific init_module routine as well,
instead of conditional code in init_module, but that means changing all
architectures. Not today.
