Subject: [PATCH v2 05/16] KVM: arm64: Rename KVM_PTE_LEAF_ATTR_S2_IGNORED
Date: Mon, 26 Jul 2021 10:28:54 +0100	[thread overview]
Message-ID: <20210726092905.2198501-6-qperret@google.com> (raw)
In-Reply-To: <20210726092905.2198501-1-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. And while at it, since these bits are more
commonly known as 'software' bits, rename accordingly.
