  "message": "powerpc/vdso: Filter clang\u0027s auto var init zero enabler when linking\n\nAfter commit 8d9acfce3332 (\"kbuild: Stop using \u0027-Qunused-arguments\u0027 with\nclang\"), the PowerPC vDSO shows the following error with clang-13 and\nolder when CONFIG_INIT_STACK_ALL_ZERO is enabled:\n\n  clang: error: argument unused during compilation: \u0027-enable-trivial-auto-var-init-zero-knowing-it-will-be-removed-from-clang\u0027 [-Werror,-Wunused-command-line-argument]\n\nclang-14 added a change to make sure this flag never triggers\n-Wunused-command-line-argument, so it is fixed with newer releases. For\nolder releases that the kernel still supports building with, just filter\nout this flag, as has been done for other flags.\n\nFixes: f0a42fbab447 (\"powerpc/vdso: Improve linker flags\")\nFixes: 8d9acfce3332 (\"kbuild: Stop using \u0027-Qunused-arguments\u0027 with clang\")\nLink: https://github.com/llvm/llvm-project/commit/ca6d5813d17598cd180995fb3bdfca00f364475f\nSigned-off-by: Nathan Chancellor \u003cnathan@kernel.org\u003e\nSigned-off-by: Masahiro Yamada \u003cmasahiroy@kernel.org\u003e\n",
