#     KVM: PPC: Book3s: mmio: Deliver DSI after emulation failure
#     
#     MMIO emulation can fail if the guest uses an instruction that we are
#     not prepared to emulate. Since these instructions can be and most
#     likely are valid ones, this is (slightly) closer to an access fault
#     than to an illegal instruction, so deliver a Data Storage interrupt
#     instead of a Program interrupt.
#     
#     BookE ignores bad faults, so it will keep using a Program interrupt
#     because a DSI would cause a fault loop in the guest.
