| 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. |
