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.
