 * This is similar to ipath_get_user_pages, but it's always one page, and we

 * mark the page as locked for I/O, and shared.  This is used for the user

 * process page that contains the destination address for the rcvhdrq tail

 * update, so we need to have the vma. If we don't do this, the page can be

 * taken away from us on fork, even if the child never touches it, and then

 * the user process never sees the tail register updates.
