[PATCH v7 2/4] KVM: arm64: Introduce mm_ops member for structure stage2_attr_data
From: Yanan Wang <hidden>
Date: 2021-06-17 10:58:55
Also in:
kvm, kvmarm, lkml
Subsystem:
arm64 port (aarch64 architecture), kernel virtual machine for arm64 (kvm/arm64), the rest · Maintainers:
Catalin Marinas, Will Deacon, Marc Zyngier, Oliver Upton, Linus Torvalds
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.
