Subject: [PATCH 08/12] KVM: arm64: Remove support for a big-endian hypervisor object
Date: Tue, 11 Aug 2026 15:01:27 +0100	[thread overview]
Message-ID: <20260811140132.22778-9-will@kernel.org> (raw)
In-Reply-To: <20260811140132.22778-1-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.
