There was this chunk in the patch, maybe it could be done nicer,
but I didn't find the nicer way.
I checked it compilation/work with(out) ia32/x32/64-bit configs
before sending.
Yeah, I know and it's just crap. WTF is wrong with:
Oh, here it is the nicer way.
I've forgot that `git grep` doesn't look into generated files.
#ifdef CONFIG_IA32_EMULATION
#include <asm/unistd_32_ia32.h>
#endif
It's not rocket science, really.
Sorry about that, I'll resend.
