From eab0b2dc4f6f34147e3d10da49ab8032e15dbea0 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Fri, 9 Jun 2017 12:49:44 +0100 Subject: KVM: arm64: vgic-v3: Add misc Group-0 handlers A number of Group-0 registers can be handled by the same accessors as that of Group-1, so let's add the required system register encodings and catch them in the dispatching function.
