| 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. |
