From 07d6f555d536aad1d74bb8b41dae9385007ecc26 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Tue, 28 Sep 2010 16:37:42 +0200 Subject: [PATCH] KVM: VMX: Add AX to list of registers clobbered by guest switch By chance this caused no harm so far. We overwrite AX during switch to/from guest context, so we must declare this.
