[Qemu-devel] [PATCH 08/58] PPC: Set MPIC IDE for IPI to 0 |

We use the IDE register with IPIs as a mask to keep track which processors
have already acknowledged the respective interrupt. So we need to initialize
it to 0 to make sure that it doesn't accidently fire an IPI on CPU0 when the
first IPI is triggered.
