There is still a risk with this approach when the Kconfig isn't entirely correct. For example, on ARM we have (I pushed a patch already): config CPU_32v6K depends on CPU_V6 config CPU_V7 select CPU_32v6K In this simple approach, we end up selecting CPU_V6 when we only need CPU_V7. There other places like this in the kernel. Of course, kbuild could still warn but if people rely on this feature to select options automatically I suspect they would ignore the warnings. -- Catalin _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
