Also, grep for READ_ONCE/WRITE_ONCE in the kernel tree if you want to see how big the issue is

I'm already aware of the comment in include/asm-generic/rwonce.h about load tearing and 64-bit loads on 32-bit architectures. That's partly why I mentioned long long alignment on i386. Perhaps, for being so common, i386 has generally lowered expectations?
