On architectures which have symbol prefixes, depmod emits lots of warnings like this: WARNING: $module.ko needs unknown symbol $symbol This is because depmod isn't being passed the -P <symbol_prefix> arguments to specify the symbol prefix to ignore. This option is included since the 3.13 release of module-init-tools. Update scripts/depmod.sh to take extra arguments for the symbol prefix (required but may be empty), and update the main Makefile to always pass "$(CONFIG_SYMBOL_PREFIX)" to scripts/depmod.sh. If the provided symbol prefix is non-empty, scripts/depmod.sh checks if depmod --version reports module-init-tools with a version number < 3.13 otherwise it appends -P $SYMBOL_PREFIX to the depmod command line.
