[PATCH v8 04/11] KVM: arm64: Pass struct kvm to per-EC handlers
From: Fuad Tabba <hidden>
Date: 2021-10-10 15:00:13
Also in:
kvm, kvmarm
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
We need struct kvm to check for protected VMs to be able to pick the right handlers for them in subsequent patches.
