From ba05b39d54eef78043b5c8ee90545cb06a98ae6f Mon Sep 17 00:00:00 2001 From: Vasily Gorbik Date: Wed, 17 Jan 2024 11:50:49 +0100 Subject: 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.
