From fc675e355e705a046df7b635d3f3330c0ad94569 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Tue, 8 Jul 2014 12:09:03 +0100 Subject: [PATCH] arm/arm64: KVM: vgic: kill VGIC_MAX_CPUS We now have the information about the number of CPU interfaces in the distributor itself. Let's get rid of VGIC_MAX_CPUS, and just rely on KVM_MAX_VCPUS where we don't have the choice. Yet.
