From 7d39f9e32c761abaa84bef7c4a4d9349ba8638e0 Mon Sep 17 00:00:00 2001 From: wanghaibin Date: Mon, 17 Nov 2014 09:27:37 +0000 Subject: [PATCH] KVM: ARM: VGIC: Optimize the vGIC vgic_update_irq_pending function. When vgic_update_irq_pending with level-sensitive false, it is need to deactivates an interrupt, and, it can go to out directly. Here return a false value, because it will be not need to kick.
