Subject: [Qemu-devel] [PATCH 6/8] spapr: init CPUState->cpu_index with index relative to core-id
Date: Thu, 21 Jul 2016 17:54:37 +0200	[thread overview]
Message-ID: <1469116479-233280-7-git-send-email-imammedo@redhat.com> (raw)
In-Reply-To: <1469116479-233280-1-git-send-email-imammedo@redhat.com>

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.
