    Shilpasri G Bhat 提交于
    Create sysfs attributes to export throttle information in
    /sys/devices/system/cpu/cpuX/cpufreq/throttle_stats directory. The
    newly added sysfs files are as follows:
    
     1)/sys/devices/system/cpu/cpuX/cpufreq/throttle_stats/turbo_stat
     2)/sys/devices/system/cpu/cpuX/cpufreq/throttle_stats/sub-turbo_stat
     3)/sys/devices/system/cpu/cpuX/cpufreq/throttle_stats/unthrottle
     4)/sys/devices/system/cpu/cpuX/cpufreq/throttle_stats/powercap
     5)/sys/devices/system/cpu/cpuX/cpufreq/throttle_stats/overtemp
     6)/sys/devices/system/cpu/cpuX/cpufreq/throttle_stats/supply_fault
     7)/sys/devices/system/cpu/cpuX/cpufreq/throttle_stats/overcurrent
     8)/sys/devices/system/cpu/cpuX/cpufreq/throttle_stats/occ_reset
    
    Detailed explanation of each attribute is added to
    Documentation/ABI/testing/sysfs-devices-system-cpu
