Subject: [PATCH 4/4] kbuild: vdso_install: drop build ID architecture allow-list
Date: Fri, 20 Mar 2026 17:36:56 +0100 [thread overview]
Message-ID: <20260320-kbuild-vdso-install-v1-4-e2e8a0970889@weissschuh.net> (raw)
In-Reply-To: <20260320-kbuild-vdso-install-v1-0-e2e8a0970889@weissschuh.net>
Many architectures which do generate build IDs are missing from this
list. For example arm64, riscv, loongarch, mips.
Now that errors from readelf and binaries without any build ID are
handled gracefully, the allow-list is not necessary anymore, drop it.
