Due to this change, the above code that sets CONFIG_X86_32 to the opposite of CONFIG_64BIT is no longer included in xor-sse.c, which uses CONFIG_X86_32. So if the above code actually did anything, this change would have broken it for xor-sse.c. However, based on arch/x86/um/Kconfig, CONFIG_X86_32 is always the opposite of CONFIG_64BIT, so the above code actually has no effect. Does that sound right? - Eric
