When using the new adr_l/ldr_l/str_l macros to refer to external symbols from modules, the linker may emit place relative ELF relocations that need to be fixed up by the module loader. So add support for these.Just wondering if that capability requirement should be added to the module signature somehow...? Maybe not. The MODULE_ARCH_VERMAGIC definition only contains things that are configurable for a given build.
It doesn't need to be. If a module contains a relocation we don't know how to handle, it will fail to load. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last! _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
