From f8210229f1f3e187ed4c40191b0101a8504b2f80 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Wed, 11 Jan 2023 20:05:06 -0700 Subject: [PATCH] s390/vdso: Drop unused '-s' flag from KBUILD_AFLAGS_64 When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, it warns: clang-16: error: argument unused during compilation: '-s' [-Werror,-Wunused-command-line-argument] The compiler's '-s' flag is a linking option (it is passed along to the linker directly), which means it does nothing when the linker is not invoked by the compiler. The kernel builds all .o files with '-c', which stops the compilation pipeline before linking, so '-s' can be safely dropped from KBUILD_AFLAGS_64.
