The S390 defconfig builds failed on the Linux stable-rc 6.6.112-rc1
and 6.12.53-rc1 tag build due to following build warnings / errors
with gcc and clang toolchains.
Also seen on 6.12.53-rc1
First seen on 6.6.112-rc1
Good: v6.6.111
Bad: 6.6.112-rc1 also seen on 6.12.53-rc1
Regression Analysis:
- New regression? Yes
- Reproducibility? Yes
