[PATCH 00/10] IB/hfi1: Clean up cdevs, convert write to ioctl, and destage driver

[Dennis Dalessandro <dennis.dalessandro-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

The purpose of this patch series is to get the hfi1 driver out of staging and
into the drivers/infiniband mainline. We have made significant changes beyond
what was originally requested in the TODO list. The biggest areas of contention
have simply been removed: snoop/capture, eprom, ui and the write()/writev()
problem has been solved. We will be working with the community to get back the
removed functionality, particularly the snoop/capture.

This patch series combines the previously posted series which converts write()
to ioctl() [1] and the previously posted series to remove cdevs [2]. These have
been merged into a single series to have a more logical order and aid in review.
For instance there is no change to convert eprom to ioctl then remove it. It is
just removed.

Other changes in this series which were not included in [1] and [2] include:

* Dropped sysfs version file
* Added a new ioctl to get the sw version
* Remove ioctl access OK helper function and rely on get_user and friends
* Adds kref object accounting for opening/closing the cdev to prevent parent
  structure from being removed.

This patch series should apply on Doug's k.o/for-4.7 branch.

Patches can also be viewed in my repo at:
https://github.com/ddalessa/kernel/tree/for-4.7
