This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

All are accepted upstream in 4.17. Three of those are already in bionic, leaving a total of 9 remaining commits needed in bionic. This pull request is for those other 9 commits. == Regression Potential == All of the commits are specific to powerpc. == Test Case == A test kernel was built with these patches and tested by IBM. == Comment: #0 - Barry B.
