Subject: [PATCH v3 08/13] KVM: arm64: Remove support for a big-endian hypervisor object
Date: Fri, 18 Sep 2026 15:52:10 +0100 [thread overview]
Message-ID: <20260918145217.1669-9-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 the support for generating
ELF relocations for a big-endian hypervisor object and drop the unused
big-endian spinlock definition from nVHE.
