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. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
