[Qemu-devel] [PATCH 05/19] target-arm: move cpu_exec_realize() to realize function

[Laurent Vivier <lvivier@redhat.com>]

I've removed the cannot_destroy_with_object_finalize_yet field as
cpu_exec_init() is not called by arm_cpu_initfn() anymore
(tested with QOM command provided by commit 4c315c27 with
 "arm1026-arm-cpu")
