[PATCH 04/18] KVM: arm64: Skip computing hyp VA layout for VHE
From: Marc Zyngier <maz@kernel.org>
Date: 2021-01-07 11:23:14
Also in:
kvm, kvmarm
Subsystem:
arm64 port (aarch64 architecture), the rest · Maintainers:
Catalin Marinas, Will Deacon, Linus Torvalds
From: David Brazdil <redacted> Computing the hyp VA layout is redundant when the kernel runs in EL2 and hyp shares its VA mappings. Make calling kvm_compute_layout() conditional on not just CONFIG_KVM but also !is_kernel_in_hyp_mode().
