From a691c8a6efe0220f244f7bb59a3af39383b57d2c Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Wed, 7 Feb 2024 17:14:56 -0700 Subject: s390: vmlinux.lds.S: explicitly keep various sections When building with CONFIG_LD_ORPHAN_WARN after selecting CONFIG_ARCH_HAS_LD_ORPHAN_WARN, there are some warnings around certain ELF sections: s390-linux-ld: warning: orphan section `.dynstr' from `arch/s390/kernel/head64.o' being placed in section `.dynstr' s390-linux-ld: warning: orphan section `.dynamic' from `arch/s390/kernel/head64.o' being placed in section `.dynamic' s390-linux-ld: warning: orphan section `.hash' from `arch/s390/kernel/head64.o' being placed in section `.hash' s390-linux-ld: warning: orphan section `.gnu.hash' from `arch/s390/kernel/head64.o' being placed in section `.gnu.hash' Explicitly keep those sections like other architectures when CONFIG_RELOCATABLE is enabled, which is always true for s390.
