So if I'm not missing something important this will make the compat syscall define available even for

CONFIG_X86_64=y CONFIG_IA32_EMULATION=n CONFIG_X86_X32=n

which is wrong because in that configuration we don't have any 32bit executable support. So why would we need a compat syscall in that case?
