From fcfdbd266a41d3e41d17666de410a24995fde03a Mon Sep 17 00:00:00 2001 From: Hollis Blanchard Date: Wed, 5 Nov 2008 09:36:24 -0600 Subject: KVM: ppc: improve trap emulation set ESR[PTR] when emulating a guest trap. This allows Linux guests to properly handle WARN_ON() (i.e. detect that it's a non-fatal trap). Also remove debugging printk in trap emulation.
