My repro is:

1. Clone and build [0]. If using Manjaro or anything else Arch-based,
   you can install llvm-git from AUR.
2. Clone the latest net-next (or mainline or linux-next or whatever).
3. Use some default distro kernel .config -- I'm using Fedora's,
   Arch/Manjaro/etc. would also work.
4. make -j$(($(nproc) + 1)) LLVM=/path/to/built/llvm-git/bin/ LLVM_IAS=1
   all
