In PR #1205, Kamalesh reports: ... I see that the -mcmodel=large flag is being passed twice with KBUILD_CFLAGS_MODULE set: gcc -Wp,-MMD,/root/.kpatch/tmp/patch/.livepatch-meminfo.mod.o.d ............ -mcmodel=medium .... -I/root/kpatch/kmod/patch -mcmodel=large -fplugin=/root/kpatch/kpatch-build/gcc-plugins/ppc64le-plugin.so ... -DMODULE -mno-save-toc-indirect -mcmodel=large -mcmodel=large -DKBUILD_BASENAME='"livepatch_meminfo.mod"' -DKBUILD_MODNAME='"livepatch_meminfo"' -D__KBUILD_MODNAME=kmod_livepatch_meminfo -c -o /root/.kpatch/tmp/patch/livepatch-meminfo.mod.o /root/.kpatch/tmp/patch/livepatch-meminfo.mod.c. I loaded the module built without the KBUILD_CFLAGS_MODULE += -mcmodel=large flag and seems to okay. I guess, we can remove the arch specific flag from the Makefile.
