+Subject: hack: arch: powerpc: drop register save/restore library from modules
+
+Upstream GCC uses a libgcc function for saving/restoring registers. This
+makes the code bigger, and upstream kernels need to carry that function
+for every single kernel module. Our GCC is patched to avoid those
+references, so we can drop the extra bloat for modules.
