    """Return system-wide CPU times as a namedtuple.
    Every CPU time represents the seconds the CPU has spent in the given mode.
    The namedtuple's fields availability varies depending on the platform:
     - user
     - system
     - idle
     - nice (UNIX)
     - iowait (Linux)
     - irq (Linux, FreeBSD)
     - softirq (Linux)
     - steal (Linux >= 2.6.11)
     - guest (Linux >= 2.6.24)
     - guest_nice (Linux >= 3.2.0)

    When percpu is True return a list of namedtuples for each CPU.
    First element of the list refers to first CPU, second element
    to second CPU and so on.
    The order of the list is consistent across calls.
