It was intentional, and I don't actually think it was even a change. The access_ok() in question is not done on the actual array that we fill up with the result of the operation, but on the address range that is being queried, and if the queried address range is bogus, we should return ENOMEM. It's even mentioned in the man-page.. We *do* return -EFAULT for the case where the "vec" array itself is not mapped.
