Following two build regressions found one on riscv and s390.

1)
Regressions on riscv build with allyesconfig and allmodconfig with toolchains
gcc-13 and clang-20 failed on stable-rc 6.6.89-rc1.

* riscv, build
  - clang-20-allmodconfig
  - gcc-13-allmodconfig
  - gcc-13-allyesconfig

Regression Analysis:
 - New regression? Yes
 - Reproducibility? Yes
