Bug Description

SRU Justification

       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The following upstream
       stable patches should be included in the Ubuntu kernel:

* HID: Add 044f:b320 ThrustMaster, Inc. 2 in 1 DT

I have removed the following commit from the Xenial tree given that it was causing a build failure on s390x.

* Revert "perf test 6: Fix missing kvm module load for s390"

This issue had already been resolved by "UBUNTU: SAUCE: Fix perf test 6: Fix missing kvm module load for s390", so the upstream fix was not needed.

    Revert "perf test 6: Fix missing kvm module load for s390"

Above patch should not have applied cleanly from linux-4.4.y because we fixed it up already. It is not mentioned above that there was anything specially done. However the committed result is not what the upstream stable did. Instead of removing a function, it gets added (a second time as the fixed up version we did is still present). Not sure how this did happen.

I have been using the stable updates toolchain that was used for the Bionic stable updates project. Generally, if a patch doesn't apply one of the tools checks to see if it was already applied. If it doesn't believe the patch is applied, and it doesn't apply cleanly, we use "patch" because it tries a little bit harder than "git am" for fitting the hunks in at different offsets.

In this case, it didn't see this patch was effectively applied under an "UBUNTU: SAUCE:" prefix. This is something that it should do, so I'll work on trying to get a patch sent for that toolchain.

Ok, but in this case the patch from upstream did a bigger hunk of removals. That would not have worked even with patch because to fix the build, we have replaced two function calls within that hunk. The change applied under the title of the revert was actually a re-do of the initial addition of that hunk. Not the revert.
