Please set it somewhere in linux-user/ and bsd-user/ instead, I would
like to keep the TCG code more similar to KVM/Xen/qtest. Probably the whole
qemu_thread_get_self(cpu->thread);
cpu->thread_id = qemu_get_thread_id();
cpu->created = true;
cpu->can_do_io = 1;
current_cpu = cpu;
should be moved into a new function (rcu_register_thread too?).
