** Description changed:

  == Justification ==
  When running the ftrace in ubunut_kernel_selftests, the "Kprobe event argument syntax" will fail on Bionic PowerPC.
  
  This is because PowerPC was not supported by this test.
  
  == Fix ==
  9855c462 (selftests/ftrace: Add ppc support for kprobe args tests)
+ This patch can be cherry-picked for Bionic and Xenial.
+ Although we don't run this ftrace test in Xenial, it will still be a plus to fix this.
+ 
+ It's already been applied in C/D.
  
  == Test ==
  Patch tested with Bionic P8. Test passed as expected:
  [23] Kprobe event argument syntax	[PASS]
  
  == Regression potential ==
  None.
  This patch is just for the kernel testing tool.
- 
  
  == Original bug report ==
  This issue was not spotted on the other arches.
