OK, so as Andrew said, it looks like Viro's conversion from aio to
iterators has a length and offset problem on 32 bits.

my suspicion is that iov_offset and count in struct iov_iter have to
become loff_t quantities ... plus a lot of other size_t to loff_t
conversions.  Hopefully Viro will fix it as a matter of urgency.
