If the intention is to check i386/x86_64 excluding UML, testing CONFIG_X86_{32,64} is simpler. The reason for checking __i386__ / __x86_64__ was perhaps because lib/raid6/algos.c is built not only for the kernel but also for testing the library code from userspace. However, lib/raid6/test/Makefile passes -DCONFIG_X86_{32,64} for this case. So, I do not see a reason to not use CONFIG option here. Signed-off-by: Masahiro Yamada <masahiroy@xxxxxxxxxx> Acked-by: H.
