Hi, we tested your kernel and here are the results:

    Overall result: FAILED
             Merge: OK
           Compile: FAILED


Kernel information:
    Commit message: Linux 6.14-rc1

You can find all the details about the test run at

One or more kernel builds failed:
    Unrecognized or new issues:

If you find a failure unrelated to your changes, please ask the test maintainer to review it.
This will prevent the failures from being incorrectly reported in the future.

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.

It looks like the build fails thanks to a rust panic:

00:00:10   EXPORTS rust/exports_helpers_generated.h
00:00:11 panicked at main.rs:52:36:
00:00:11 Unable to generate bindings: ClangDiagnostic("error: unknown argument: '-fzero-init-padding-bits=all'\n")
00:00:11 make[4]: *** [rust/Makefile:332: rust/bindings/bindings_helpers_generated.rs] Error 101

Presumably introduced by dce4aab8441d ("kbuild: Use
-fzero-init-padding-bits=all"). I'm guessing that option isn't supposed
to propagate to .rs sources?

How is that getting passed to Clang? That's a GCC-only option, with
"cc-option":

+KBUILD_CFLAGS += $(call cc-option,-fzero-init-padding-bits=all)

I will take a look...

It seems like the error comes from bindgen. Does this patch help?
