UML: define RUNTIME_DISCARD_EXIT
With CONFIG_VIRTIO_UML=y, GNU ld < 2.36 fails to link UML vmlinux (w/wo CONFIG_LD_SCRIPT_STATIC). `.exit.text' referenced in section `.uml.exitcall.exit' of arch/um/drivers/virtio_uml.o: defined in discarded section `.exit.text' of arch/um/drivers/virtio_uml.o collect2: error: ld returned 1 exit status This fix is similar to the following commits: - 4b9880dbf3bd ("powerpc/vmlinux.lds: Define RUNTIME_DISCARD_EXIT") - a494398bde27 ("s390: define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36") - c1c551bebf92 ("sh: define RUNTIME_DISCARD_EXIT") Fixes: 99cb0d917ffa ("arch: fix broken BuildID for arm64 and riscv") Reported-by: SeongJae Park <sj@kernel.org> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Tested-by: SeongJae Park <sj@kernel.org> Signed-off-by: Richard Weinberger <richard@nod.at>
