kbuild: Check for functions with ambiguous -ffunction-sections section names Commit 9c7dc1dd897a ("objtool: Warn on functions with ambiguous -ffunction-sections section names") only works for drivers which are compiled on architectures supported by objtool. Make a script to perform the same check for all architectures.

kbuild: prefer ${NM} in check-function-names.sh The check-function-names.sh scripts invokes 'nm' directly and this can be problematic during cross-compilation when the toolchain is different from the system's default (e.g. LLVM=1). scripts/check-function-names.sh: nm: not found Let's prefer the ${NM} variable which is already set by kbuild. However, still fallback to plain 'nm' to ensure the script is still usable when called directly.
