We already have a *bunch* of linker tables in Linux, mostly the init tables, but they are all built in an ad hoc manner which requires linker script modifications, which are of course per architecture. My desire would be to make a general linker table facility so that a new linker table can be implemented by changing C code only. -hpa -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
