   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.
