s390/expoline: Make modules use kernel expolines
Currently, kernel modules contain their own set of expoline thunks. In the case of EXPOLINE_EXTERN, this involves postlinking of precompiled expoline.o. expoline.o is also necessary for out-of-source tree module builds. Now that the kernel modules area is less than 4 GB away from kernel expoline thunks, make modules use kernel expolines. Also make EXPOLINE_EXTERN the default if the compiler supports it. This simplifies build and aligns with the approach adopted by other architectures. Signed-off-by: Vasily Gorbik <gor@linux.ibm.com> Signed-off-by: Alexander Gordeev <agordeev@linux.ibm.com>
