Title:
  Ubuntu14.04: /sys/bus/pci/slots show weird numbers as slot_name on
  PPC64LE

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  ---Problem Description---
  root@powerio-le21:/sys/bus/pci/slots# ls -l
  total 0
  drwxr-xr-x 2 root root 0 Jul 15 21:03 1
  drwxr-xr-x 2 root root 0 Jul 15 21:03 16

  In /sys/bus/pci/slots directory, there are bunch of numbers. What
  these numbers mean? Do we expect slot_name for each pci device here?

  Some applications read these number as slot_name for pci device. For
  example, there is a Solstice SAS adapter on this system, when we dump
  detail information for this adapter, we got "Platform Location = 8".

  ---Steps to Reproduce---
  iprconfig->1
   
  In other distros, we see the real location code in this directory. For example:

  [root@jupiter1-lp1 slots]# pwd
  /sys/bus/pci/slots

  drwxr-xr-x. 2 root root 0 Jul  9 12:15 UTMP3.C02.01AC022-P1-C10
  drwxr-xr-x. 2 root root 0 Jul  9 12:15 UTMP3.C02.01AC022-P1-C2
  drwxr-xr-x. 2 root root 0 Jul  9 12:15 UTMP3.C02.01AC022-P1-C3
  drwxr-xr-x. 2 root root 0 Jul  9 12:15 UTMP3.C02.01AC022-P1-C9

  or in PowerKVM, It is empty in /sys/bus/pci/slots.

  In Ubuntu, these random numbers break some code in iprconfig. What is
  generating these in Ubuntu?

  Thanks,
  Wendy
