[PATCH 03/14] arm64: KVM: Drop VHE-specific HYP call stub
From: Christoffer Dall <hidden>
Date: 2019-01-24 14:01:45
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
From: Marc Zyngier <redacted> We now call VHE code directly, without going through any central dispatching function. Let's drop that code.
