From c0f98ea0e7eafb3ca5ea4a178de6d0ce36333ae7 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Wed, 7 Feb 2024 17:15:01 -0700 Subject: s390/boot: vmlinux.lds.S: handle commonly discarded sections When building with CONFIG_LD_ORPHAN_WARN after selecting CONFIG_ARCH_HAS_LD_ORPHAN_WARN, there are several series of warnings from the various discardable sections that the kernel adds for build purposes that are not needed at runtime: s390-linux-ld: warning: orphan section `.export_symbol' from `arch/s390/boot/decompressor.o' being placed in section `.export_symbol' s390-linux-ld: warning: orphan section `.discard.addressable' from `arch/s390/boot/decompressor.o' being placed in section `.discard.addressable' s390-linux-ld: warning: orphan section `.modinfo' from `arch/s390/boot/decompressor.o' being placed in section `.modinfo' include/asm-generic/vmlinux.lds.h has a macro for easily discarding these sections across the kernel named COMMON_DISCARDS, use it to clear up the warnings.
