Subject: [PATCH v6 2/4] KVM: arm64: Introduce mm_ops member for structure stage2_attr_data
Date: Wed, 16 Jun 2021 17:51:58 +0800 [thread overview]
Message-ID: <20210616095200.38008-3-wangyanan55@huawei.com> (raw)
In-Reply-To: <20210616095200.38008-1-wangyanan55@huawei.com>
Also add a mm_ops member for structure stage2_attr_data, since we
will move I-cache maintenance for guest stage-2 to the permission
path and as a result will need mm_ops for some callbacks.
