Hello,

We ran automated tests on a recent commit from this kernel tree:

       Kernel repo: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git
            Commit: ee00910f75ff - powerpc/powernv/vas: Release reference to tgid during window close

The results of these automated tests are provided below.

    Overall result: FAILED (see details below)
             Merge: OK
           Compile: FAILED

All kernel binaries, config files, and logs are available for download here:

  https://arr-cki-prod-datawarehouse-public.s3.amazonaws.com/index.html?prefix=datawarehouse-public/2021/07/15/337656806

We attempted to compile the kernel for multiple architectures, but the compile
failed on one or more architectures:

           ppc64le: FAILED (see build-ppc64le.log.xz attachment)
            x86_64: FAILED (see build-x86_64.log.xz attachment)

We hope that these logs can help you find the problem quickly. For the full
detail on our testing procedures, please scroll to the bottom of this message.

Please reply to this email if you have any questions about the tests that we
ran or if you have any suggestions on how to make future tests more effective.

Are you sure?  I fixed a different build bug in that area a few hours
ago, if you rebuild the tree it should be resolved.

If not, please let me know.

Yes. All runs of the queue hit the problem, including the latest
b438694730fd. I also ran a test of the second latest completed
run with a patch revert and the issue disappeared.

That said, the c139bde0fdca rebase (second latest) introduced
an s390x compilation problem that did not happen before. It
is also visible with the latest head. I don't know what commit
introduced it yet as the run barely finished:

I hit this same failure building in koji.  All of the s390 patches are
related, and appear to be an incomplete set:


s390-signal-switch-to-using-vdso-for-sigreturn-and-syscall-restart.patch
s390-vdso64-add-sigreturn-rt_sigreturn-and-restart_syscall.patch
s390-vdso-add-minimal-compat-vdso.patch
s390-vdso-always-enable-vdso.patch
s390-vdso-rename-vdso64_lbase-to-vdso_lbase.patch
