We ran automated tests on a patchset that was proposed for merging into this kernel tree. The patches were applied to:
Kernel repo: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git Commit: d3da1f09fff2 - Linux 5.0.10The results of these automated tests are provided below.
Overall result: FAILED (see details below) Merge: OK Compile: FAILEDWe attempted to compile the kernel for multiple architectures, but the compile failed on one or more architectures:
s390x: FAILED (see build-s390x.log.xz attachment)We took another look at this one and the failure seems to be valid after retrying the build. The same issue cropped up both times:

We spotted this recently in mainline as well.
Yeah, a patch to fix this was just submitted upstream, hopefully it lands soon, or I will pull this out of the tree.
