Roughly (without looking back as fs/pipe.c). When you have your
patch, you will need to restart this discussion on the linux-kernel
mailing list (since you'll be touching a generic file). Some random
grepping for PAGE_SIZE (well PAGE_SHIFT) shows that some
other artchitectures have some support for page size > PIPE_BUF.
So there should be some interest in this fix.
