  ---Problem Description---
  cpupower monitor shows multiple stop Idle_Stats
   

   
  ---uname output---
  Linux zz376p1 4.10.0-26-generic #30~16.04.1-Ubuntu SMP Tue Jun 27 09:38:48 
UTC 2017 ppc64le ppc64le ppc64le GNU/Linux
   
  Machine Type = P9 
   
  ---Debugger---
  A debugger is not configured
   
  ---Steps to Reproduce---
  Install a P9 8375-42A Hardware with Ubuntu 16.04.3 OS.
  Then execute the cpupower monitor command to fetch all the Idle_Stats values.

  root@zz376p1:~# cpupower monitor
                |Idle_Stats
  PKG |CORE|CPU | snoo | stop | stop
     0|   8|   0|  0.00|  0.00|  2.79
     0|   8|   1|  0.00|  0.00| 70.68
     0|   8|   2|  0.00|  0.00| 99.87
     0|   8|   3|  0.00|  0.00| 67.28
     0|  12|   4|  0.00|  0.00|  5.17
     0|  12|   5|  0.00|  0.00| 12.50
     0|  12|   6|  0.00|  0.00| 99.74
     0|  12|   7|  0.00|  0.00|  0.00
     8|2048|   8|  0.00|  0.00| 22.14
     8|2048|   9|  0.00|  0.00| 102.3
     8|2048|  10|  0.00|  0.00|  0.00
     8|2048|  11|  0.00|  0.00| 99.97
     8|2052|  12|  0.00|  0.00| 99.70
     8|2052|  13|  0.00|  0.00| 23.86
     8|2052|  14|  0.00|  0.00| 113.1
     8|2052|  15|  0.00|  0.00|  0.00

  As can be seen it shows 2 columns for stop.

  There are 3 idle_stats (3 states) in this system.

  cpu monitor will print the results of all the 3 available idle_stats .

  The first stop -> stop0_lite stats
  and
  The second stop -> stop1_lite stats.

  cpupower monitor header prints the header list by getting the name of
  the idle stats.

  name          (name description)
  snoo   [T] -> snooze
  stop   [T] -> stop0_lite
  stop   [T] -> stop1_lite

  We can change the header to be more meaningful so user won't interpret
  it as 2 columns for stop.

  May be we need to change the code to print the header to use name description 
instead of name.
  .
  I will work on the patch and get it resolve.

  I have executed the command again with the fixed cpupower utility.

  
  Submitted patch upstream and awaiting response.
