Title:
  [SRU] lscpu reports incorrect number of NUMA nodes on systems with
  discontinuous NUMA nodes

Status in util-linux package in Ubuntu:
  Fix Released
Status in util-linux source package in Trusty:
  Fix Committed

Bug description:
  [Impact]
  Running 'lscpu' on a system with discontinuous NUMA nodes (such as some IBM Power 8 hardware) will only display the continuous NUMA nodes.  Users may be confused due to incorrect information.

  [Test Case]
  On a system with discontinuous NUMA nodes, just run the lscpu command
  # ls -d /sys/devices/system/node/node*
  /sys/devices/system/node/node0  /sys/devices/system/node/node1  /sys/devices/system/node/node16  /sys/devices/system/node/node17
  # lscpu|grep NUMA
  NUMA node(s):          2
  NUMA node0 CPU(s):     0-39
  NUMA node1 CPU(s):     40-79

  [Regression Potential]
  Since this is an informational command, anything relying on its output may experience new behavior.


  This affects Trusty, but Utopic and Vivid are based on newer upstream
  releases that don't include this error.
