---Problem Description---
/sys/class/scsi_host/host0/partition_number and .../mad_version showing up BE on LE Ubuntu.
 
---uname output---
Linux neo34 3.19.0-10-generic #10-Ubuntu SMP Mon Mar 23 16:18:35 UTC 2015 ppc64le ppc64le ppc64le GNU/Linux
 
---Additional Hardware Info---
Dual VIOS, Ubuntu partition is full virtual. 

 
---Patches Installed---
VMC device driver for Neo project.  Ask Steve Royer (seroyer@us) if it matters.
 
Machine Type = type_model=8247-22L 
 
---Debugger---
A debugger is not configured
 
---Steps to Reproduce---
 neo@neo34:/sys/class/scsi_disk$ cat /sys/module/ibmvscsi/drivers/vio\:ibmvscsi/30000006/host1/scsi_host/host1/partition_number 
50331648
neo@neo34:/sys/class/scsi_disk$ cat /sys/module/ibmvscsi/drivers/vio\:ibmvscsi/30000006/host1/scsi_host/host1/mad_version 
16777216

Turns out these numbers are really big-endian versions of their real values.
In [60]: print("0x%x" % 50331648)
0x3000000

The actual partition ID of host1 is 3.
neo@neo34:/sys/class/scsi_disk$ lssyscfg -r lpar -F lpar_id --filter lpar_names=vios2
3

 
Userspace tool common name: Not sure what this means.  Use 'cat' to reproduce the bug. 
 
The userspace tool has the following bit modes: ? 

Userspace rpm: Not sure what this means either.  And I'm on Ubuntu, no
RPMs.

Userspace tool obtained from project website:  na
