- 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.
