Message-Id: <20240207-s390-lld-and-orphan-warn-v1-11-8a665b3346ab@kernel.org> Date: Wed, 07 Feb 2024 17:15:03 -0700 From: Nathan Chancellor <nathan@...nel.org> To: hca@...ux.ibm.com, gor@...ux.ibm.com, agordeev@...ux.ibm.com Cc: borntraeger@...ux.ibm.com, svens@...ux.ibm.com, maskray@...gle.com, ndesaulniers@...gle.com, linux-s390@...r.kernel.org, linux-kernel@...r.kernel.org, llvm@...ts.linux.dev, patches@...ts.linux.dev, Nathan Chancellor <nathan@...nel.org> Subject: [PATCH 11/11] s390: Link vmlinux with '-z notext' ld.bfd defaults to '-z notext' (although it is customizable with the '--enable-textrel-check' configure option) but ld.lld defaults to '-z text', which causes issues with building the kernel due to the presence of dynamic relocations in sections that are not writable. ld.lld: error: relocation R_390_64 cannot be used against local symbol; recompile with -fPIC Add '-z notext' to avoid these errors, as this is expected, which matches other architectures.
