Title:
  Ubuntu - Fixing RTAS call from xmon (running ppc64le on PowerVM)

Status in linux package in Ubuntu:
  New

Bug description:
  ---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:
