Subject: [PATCH v2 05/16] KVM: arm64: Pass the walk_info structure to compute_par_s1()
Date: Mon, 15 Sep 2025 12:44:40 +0100 [thread overview]
Message-ID: <20250915114451.660351-6-maz@kernel.org> (raw)
In-Reply-To: <20250915114451.660351-1-maz@kernel.org>
Instead of just passing the translation regime, pass the full
walk_info structure to compute_par_s1(). This will help further
chamges that will require it.
