In the function cpu_exec_init_all(), the call to cpu_gen_init() (and I suppose to io_mem_init()) is still required. So we can not move the whole function to tcg_init(). But I can maybe use "if (!tcg_enabled())" instead of a check to xen. Until no tcg code is use when kvm/xen is enabled. -- Anthony PERARD
