I'm not sure if it's a bug. As you may notice, in
arch/parisc/include/uapi/asm/socket.h, it has its own management of
definitions.

I'm worried that since this file is uapi, is it allowed to adjust the
number like this patch does if it's not a bug.

Otherwise, the change looks good to me.

Thanks,
Jason
