---Problem Description---
The commit 3b8a3c010969 ("powerpc/pseries: Fix endiannes issue in RTAS call from xmon") was fixing an endianness issue in the call made from xmon to RTAS. However, as Michael Ellerman noticed, this fix was not complete, the token value was not byte swapped. This lead to call an unexpected and most of the time unexisting RTAS function, which is silently ignored by RTAS.
This bug is opened to ensure Linux distro will taking up this upstream patch:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e6eb2eba494d6f99e69ca3c3748cd37a2544ab38
This bug is affecting Ubuntu 15.04 and 15.10. |

[Test Case]
# echo x > /proc/sysrq-trigger
This should put us in the xmon debugger without errors.
