6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Huacai Chen chenhuacai@loongson.cn
commit e67e0eb6a98b261caf45048f9eb95fd7609289c0 upstream.
LoongArch's toolchain may change the default code model from normal to medium. This is unnecessary for kernel, and generates some relocations which cannot be handled by the module loader. So explicitly specify the code model to normal in Makefile (for Rust 'normal' is 'small').
