How can they be defined? It might be that the kernel version you are using has not exported these symbols, in this case you need to export these symbols explicitly using EXPORT_SYMBOL macro in the relevent files of the kernel sources and then re-compile the kernel and boot your machine with new kernel image, then try to load the module. Before doing all this, just check if your current kernel has expoted these symbols or not. Do grep the function name into file /proc/ksyms. If these function names are not present there in this file that means these are not exported.
