    [S390] /proc/stat idle field for idle cpus · e1c80530
    Martin Schwidefsky authored
    The cpu idle field in the output of /proc/stat is too small for cpus
    that have been idle for more than a tick. Add the architecture hook
    arch_idle_time that allows to add the not accounted idle time of a
    sleeping cpu without waking the cpu.
    
    The s390 implementation of arch_idle_time uses the already existing
    s390_idle_data per_cpu variable to find the sleep time of a neighboring
    idle cpu.
