Module symbols have a limited length, but currently the build system allows the build finishing even if the driver code contains a too long symbol name, which eventually overflows the modversion_info[] item. The compiler may catch at compiling *.mod.c like CC xxx.mod.o xxx.mod.c:18:16: warning: initializer-string for array of chars is too long but it's merely a warning. This patch adds the check of the symbol length in modpost and stops the build properly. Currently MODULE_NAME_LEN is defined in modpost.c instead of referring to the definition in kernel header because including linux/module.h is messy and we must cover cross-compilation.
