Subject: [PATCH 04/14] KVM: arm64: Rename KVM_PTE_LEAF_ATTR_S2_IGNORED
Date: Mon, 19 Jul 2021 11:47:25 +0100 [thread overview]
Message-ID: <20210719104735.3681732-5-qperret@google.com> (raw)
In-Reply-To: <20210719104735.3681732-1-qperret@google.com>
The ignored bits for both stage-1 and stage-2 page and block
descriptors are in [55:58], so rename KVM_PTE_LEAF_ATTR_S2_IGNORED to
make it applicable to both.
