---Problem Description---
Kernel fails to invoke xmon, instead print following messages

System Dump Info:
The system is not configured to capture a system dump.
This patch has been sent upstream: http://patchwork.ozlabs.org/patch/413744/ |
SRU Justification:
[Impact]
Users of LE Power8 hardware might not be able to use XMON properly.
[Test Case]
# echo x > /proc/sysrq-trigger
This should put us in the xmon debugger without errors.
[Fix]
3b8a3c01096925a824ed3272601082289d9c23a5 can be cleanly cherry-picked to 3.13/3.16. It only adds cpu_to_be32 macros which shouldn't change the behavior of BE mode CPUs.
