Subject: [PATCH 3/4] KVM: arm64: nv: Move full s2_mmu unmap over to kvm_stage2_unmap_all()
Date: Sat, 12 Sep 2026 11:48:33 +0100 [thread overview]
Message-ID: <20260912104834.3093878-4-maz@kernel.org> (raw)
In-Reply-To: <20260912104834.3093878-1-maz@kernel.org>
Now that we have kvm_stage2_unmap_all(), use it when getting rid of a
shadow S2 MMU.
