From 4ce7ebdfc69d1d5d166eec103ed2976eb45a6173 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Sun, 26 Oct 2014 23:18:14 +0000 Subject: [PATCH] arm/arm64: KVM: dont rely on a valid GICH base address To check whether the vGIC was already initialized, we currently check the GICH base address for not being NULL. Since with GICv3 we may get along without this address, lets use the irqchip_in_kernel() function to detect an already initialized vGIC.
