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.
