KVM: PPC: Emulate trap SRR1 flags properly
Book3S needs some flags in SRR1 to get to know details about an interrupt. One such example is the trap instruction. It tells the guest kernel that a program interrupt is due to a trap using a bit in SRR1. This patch implements above behavior, making WARN_ON behave like WARN_ON.
