4 Subject: hack: arch: powerpc: drop register save/restore library from modules
5  
6 Upstream GCC uses a libgcc function for saving/restoring registers. This
7 makes the code bigger, and upstream kernels need to carry that function
8 for every single kernel module. Our GCC is patched to avoid those
9 references, so we can drop the extra bloat for modules.
