charset="utf-8" QEMU will be terminated if the specified CPU type isn't supported in machine_run_board_init(). The list of supported CPU type names is tracked by mc->valid_cpu_types. The error handling can be used to propagate error messages, to be consistent how the errors are handled for other situations in the same function. No functional change intended.
