ppc64el versions of the Xenial test kernel are now available here:
http://kernel.ubuntu.com/~jsalisbury/lp1762928/xenial
Xenial required the following two prereq commits:

Bug description:
---Problem Description---
tm_trap_test failed on P8 compat mode [16.04.04 daily build as well bionic ]
guests on a P9 host running bionic final beta version.
Contact Information = srikanth/[email protected]
---uname output---
16.04.04 Guest running in P8compat mode:
Linux guest 4.15.0-15-generic #16~16.04.1-Ubuntu SMP Thu Apr 5 12:18:22 UTC
2018 ppc64le ppc64le ppc64le GNU/Linux
18.04 guest running in P8compat mode:
Linux ubuntu 4.15.0-15-generic #16-Ubuntu SMP Wed Apr 4 13:57:51 UTC 2018
ppc64le ppc64le ppc64le GNU/Linux
Machine Type = boston-LC
---Debugger---
A debugger is not configured
---Steps to Reproduce---
1. Log into P9 Ubuntu 18.04 host, take console of guest
`srikanth_ubuntu160404`
2. Run TM selftests
git clone --depth 1 https://github.com/torvalds/linux.git;cd
linux/tools/testing/selftests/powerpc/;git log --oneline -1;make;make -C tm
run_tests
We will observe one of the tm tests failing, mentioned below:
selftests: tm-trap
========================================
test: tm_trap_test
tags: git_version:c18bb39
Little-Endian machine detected. Checking if endianness flips inadvertently on
trap in TM... yes!
failure: tm_trap_test
not ok 1..11 selftests: tm-trap [FAIL]
Expected result: All tm selftests should have been pass on the P8 compat
guest.. giventhat we had TM workaround patches in latest Ubuntu BIONIC host
kernel
Stack trace output:
no
Oops output:
no
System Dump Info:
The system is not configured to capture a system dump.
*Additional Instructions for srikanth/[email protected]:
