Title:
  Huge PCI BAR support needed for Ubuntu 14.10

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Utopic:
  Fix Released

Bug description:
  == Comment: #0 - Brian Hart <hartb@xxxxxxxxxx> - 2014-08-04 17:26:34 ==
  ---Problem Description---
  Our project requires Huge BAR Support (i.e. support for PCI BAR spaces > 1G) in Ubuntu 14.10.  Guo and Gavin are working on the kernel changes (and Sapphire/OPAL changes?) and have already submitted patches.  The patches did not make the 3.16 cut-off, so will need to be back-ported to the 14.10 kernel.

  I believe the patches are the set described by:

  https://lists.ozlabs.org/pipermail/linuxppc-dev/2014-July/119170.html
   
  Contact Information = Brian Hart (hartb@xxxxxxxxxx), Dave Marquardt (davemarq@xxxxxxxxxx) 
   
  ---uname output---
  Linux tul115p1 3.16.0-6-generic #11-Ubuntu SMP Mon Jul 28 02:00:45 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux
   
  ---Additional Hardware Info---
  Problem is seen with PCI adapters that request > 1G of BAR space.  We've seen it with GPUs that request a BAR1 of size 16G. 

   
  Machine Type = 8286-42A 
   
  ---Debugger---
  A debugger is not configured
   
  ---Steps to Reproduce---
   Add a PCI adapter which requests huge BAR space in the system.  The huge BARs will not be assigned and the adapter will likely not initialize.
   
  Stack trace output:
   no
   
  Oops output:
   no
   
  System Dump Info:
    The system is not configured to capture a system dump.
   
  *Additional Instructions for Brian Hart (hartb@xxxxxxxxxx), Dave Marquardt (davemarq@xxxxxxxxxx): 
  -Attach sysctl -a output output to the bug.
