KVM: PPC: Book3S HV: Don't crash host on unknown guest interrupt
If we come out of a guest with an interrupt that we don't know about, instead of crashing the host with a BUG(), we now return to userspace with the exit reason set to KVM_EXIT_UNKNOWN and the trap vector in the hw.hardware_exit_reason field of the kvm_run structure, as is done on x86. Note that run->exit_reason is already set to KVM_EXIT_UNKNOWN at the beginning of kvmppc_handle_exit(). Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Alexander Graf <agraf@suse.de>
