Subject: [PATCH] UML: define RUNTIME_DISCARD_EXIT
Date: Wed, 8 Feb 2023 01:41:56 +0900 [thread overview]
Message-ID: <20230207164156.537378-1-masahiroy@kernel.org> (raw)
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")
