[Qemu-devel] [PATCH 6/8] spapr: init CPUState->cpu_index with index relative to core-id

[Igor Mammedov]

It will enshure that cpu_index for a given cpu stays the same
regardless of the order cpus has been created/deleted and so
it would be possible to migrate QEMU instance with out of order
created CPU.
