There are three build regressions and two build warnings.
1)
Regressions on x86_64 with defconfig builds with clang-nightly toolchain
on the stable-rc 6.1.136-rc1.
* x86_64, build
- clang-nightly-lkftconfig
- clang-nightly-x86_64_defconfig
Regression Analysis:
- New regression? Yes
- Reproducibility? Yes
