Subject: [PATCH 0/2] aio: fix the vectored aio routines

Hi,

It was reported[1] that 32 bit readv and writev AIO operations were
not functioning properly.  It turns out that the code to convert the
32bit io vectors to 64 bits was never written.  The results of that
can be pretty bad, but in my testing, it mostly ended up in generating
EFAULT as we walked off the list of I/O vectors provided.

This patch set fixes the problem in my environment.  Comments, as always,
are greatly appreciated.

Cheers,
Jeff
