| Subject: [PATCH] powerpc/le: Avoid creatng R_PPC64_TOCSAVE relocations for |
| modules. |
| |
| When building modules with a native le toolchain the linker will |
| generate R_PPC64_TOCSAVE relocations when it's safe to omit saving r2 on |
| a plt call. This isn't helpful in the conext of a kernel module and the |
| kernel will fail to load those modules with an error like: |
| nf_conntrack: Unknown ADD relocation: 109 |
| |
| This patch tells the linker to avoid createing R_PPC64_TOCSAVE |
| relocations allowing modules to load. |
