I just thought it was a good idea to scan builtin.modules in the name uniqueness checking, but a couple of false positives were found. Stephen reported a false positive for ppc64_defconfig: warning: same basename if the following are built as modules: arch/powerpc/platforms/powermac/nvram.ko drivers/char/nvram.ko The former is never built as a module as you see in arch/powerpc/platforms/powermac/Makefile: # CONFIG_NVRAM is an arch. independent tristate symbol, for pmac32 we really # need this to be a bool. Cheat here and pretend CONFIG_NVRAM=m is really # CONFIG_NVRAM=y obj-$(CONFIG_NVRAM:m=y) += nvram.o Another example of false positive is arm64 defconfig: warning: same basename if the following are built as modules: arch/arm64/lib/crc32.ko lib/crc32.ko It is true CONFIG_CRC32 is a tristate option but it is always 'y' since it is select'ed by ARM64. Hence, neither of them is built as a module for the arm64 build. From the above, modules.builtin essentially contains false positives. I do not think it is a big deal as far as kmod is concerned, but false positive warnings in the kernel build make people upset. It is better to not check it. Even without builtin.modules checked, we have enough (and more solid) test coverage with allmodconfig. While I touched this part, I replaced the sed code with neater one provided by Stephen.
