We have had at least one instance where failing to do this caused an arch (arm) to emit a short-mode address offset to a function which it thought was in the same section as the callsite. Only the target was in a different section from the callsite and the linker couldn't fit the needed offset into the operand. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
