Thanks Nathan, that was quick!

I tried it, and it worked like a charm. bindgen reports:

    $ bindgen --version --verbose
    bindgen 0.65.1
    Clang: ClangBuiltLinux clang version 18.1.0rc
(https://github.com/llvm/llvm-project.git
c6c86965d967886ca5a2ed8968c949cd42cdd49a)

 And I built next-20240213 for LoongArch kernel with Rust enabled:

    # Linux/loongarch 6.8.0-rc4 Kernel Configuration
    CONFIG_CC_VERSION_TEXT=3D"ClangBuiltLinux clang version 18.1.0rc

    CONFIG_WERROR=3Dy
    CONFIG_RUST=3Dy
    CONFIG_RUSTC_VERSION_TEXT=3D"rustc 1.75.0 (82e1608df 2023-12-21)"
    CONFIG_BINDGEN_VERSION_TEXT=3D"bindgen 0.65.1"

I also built our rust-next branch for x86_64 and QEMU-boot tested it
with the couple Rust samples:

    [ 0.000000] Linux version 6.8.0-rc1-gf090f0d0eea9

I have hooked it up into my small CI to keep using your toolchain in a
subset of the builds :)

Not sure if you pick tags for this sort of thing, but in case it is useful:

Thanks again!
