Hello,

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

       Kernel repo: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
            Commit: f1583cb1be35 - Merge tag 'linux-kselftest-next-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

The results of these automated tests are provided below.

    Overall result: FAILED (see details below)
             Merge: OK
           Compile: FAILED
 Selftests 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/2021/09/03/365103273

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)
             s390x: FAILED (see build-s390x.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.

Compile testing
---------------

We compiled the kernel for 4 architectures:

    aarch64:
      make options: make LLVM=1 -j24 INSTALL_MOD_STRIP=1 targz-pkg

    ppc64le:
      make options: make CC=clang -j24 INSTALL_MOD_STRIP=1 targz-pkg

    s390x:
      make options: make CC=clang -j24 INSTALL_MOD_STRIP=1 targz-pkg

    x86_64:
      make options: make LLVM=1 -j24 INSTALL_MOD_STRIP=1 targz-pkg


We built the following selftests:

  x86_64:
      net: OK
      bpf: fail
      install and packaging: OK

You can find the full log (build-selftests.log) in the artifact storage above.

This is caused by the implicit switch to the integrated assembler in commit
f12b034afeb3 ("scripts/Makefile.clang: default to LLVM_IAS=1"). Please add
'LLVM_IAS=0' to the 'CC=clang' commands above and the build should be back to
passing like before.

Cheers,
Nathan

Thank you! I filed [1][2] to fix/track this.
