Subject: [PATCH v5 3/6] KVM: arm64: Add mm_ops member for structure stage2_attr_data
Date: Thu, 15 Apr 2021 19:50:29 +0800 [thread overview]
Message-ID: <20210415115032.35760-4-wangyanan55@huawei.com> (raw)
In-Reply-To: <20210415115032.35760-1-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 address transformation.
