+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.
