Build regressions were detected on multiple architectures (arm, arm64,
riscv) with the Linux next-20250818 tag when building with Rust-enabled
configurations (rust-gcc and rust-clang) from selftests/rust/config.
Duplicate definition of ARCH_KMALLOC_MINALIGN in Rust bindings is
causing build failures across affected toolchains.
First seen on next-20250818
Good: next-20250815
Bad: next-20250818 and next-20250819
Regression Analysis:
- New regression? yes
- Reproducibility? yes
