Hi list, Should I provide more detailed information on the problem that the patch solves? In short, I just run depmod -ae -F System.map -P _ on modules and kernel cross-compiled for Blackfin and see lots of undefined symbols, which are in fact defined by the kernel. For example, WARNING: module.ko needs unknown symbol _memcpy WARNING: module.ko needs unknown symbol _printk WARNING: module.ko needs unknown symbol ___kmalloc This is because all symbols are prefixed with _ for Blackfin and kmod's depmod handles -P switch incorrectly.

Also, prevent inserted fake symbols (like "__this_module") from being wrongly truncated from beginning.
