[Qemu-devel] [PATCH v2 16/20] target-tilegx: move cpu_exec_realize() to realize function

[Laurent Vivier <lvivier@redhat.com>]

I've removed the cannot_destroy_with_object_finalize_yet field as
unsafe references have been moved to cpu_exec_realize().
(not tested with QOM command as tilegx is only available in linux-user
 mode)
