From 0b09b6e51931ef5b4e0d7adee0a666c7f4b1867b Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Sat, 18 Mar 2017 13:41:54 +0100 Subject: [PATCH] KVM: arm/arm64: vgic: Don't check vgic_initialized in sync/flush Now when we do an early init of the static parts of the VGIC data structures, we can do things like checking if the AP lists are empty directly without having to explicitly check if the vgic is initialized and reduce a bit of work in our critical path.
