I have altered this patch to provide the listio support through a
separate syscall.

The code is in RFC stage at the moment and is only compile-tested on
i386. I have refrained from modifying unistd.h for now in order to
avoid touching too many files. I plan to do actual tests (which
involves user space changes to aio libraries) only if there is an
agreement with this syscall approach.

More details about the interface are in the patch itself.

Regards,
Bharata.
