3.2.81-rc1 review patch. If anyone has any objections, please let me know.

commit e6bd18f57aad1a2d1ef40e646d03ed0f2515c9e3 upstream.
The drivers/infiniband stack uses write() as a replacement for
bi-directional ioctl(). This is not safe. There are ways to
trigger write calls that result in the return structure that
is normally written to user space being shunted off to user
specified kernel memory instead.
