From 67c9dddc95ac16a09db996e8e4dcacfd94cf2306 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 10 May 2016 17:01:23 +0200 Subject: [PATCH] KVM: x86: make hwapic_isr_update and hwapic_irr_update look the same MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Neither APICv nor AVIC actually need the first argument of hwapic_isr_update, but the vCPU makes more sense than passing the pointer to the whole virtual machine! In fact in the APICv case it's just happening that the vCPU is used implicitly, through the loaded VMCS. The second argument instead is named differently, make it consistent.
