Subject: [PATCH v3 07/13] arm64: vdso32: Always build compat vDSO object as little-endian
Date: Fri, 18 Sep 2026 15:52:09 +0100 [thread overview]
Message-ID: <20260918145217.1669-8-will@kernel.org> (raw)
In-Reply-To: <20260918145217.1669-1-will@kernel.org>
Big-endian support on arm64 depends on BROKEN. In preparation for
removing the dead code altogether, remove support for building a
big-endian 32-bit vDSO.
