[Qemu-devel] [PULL 44/44] monitor: fix crash for platforms without a CPU 0 |

Now that we allow CPU hot unplug on a few platforms, we can end up in a
situation where we don't have a CPU with index 0. Or at least we could,
if we didn't have code to explicitly prohibit unplug of CPU 0.
Longer term we want to allow CPU 0 unplug, this patch is an early step in
allowing this, by removing an assumption in the monitor code that CPU 0
always exists.
