2c83f58161 drm/sti: Use 64-bit timestamps
'struct timespec' uses a 32-bit field for seconds, which
will overflow in year 2038 and beyond. This patch is part
of a larger attempt to remove instances of timeval, timespec
and time_t, all of which suffer from the y2038 issue, from the
kernel.

Again a pile of things all over
- Conversion to rst from docbook from Jani. Looks real pretty, and the
  source is now actually readable (compared to horrible, horrible docbook
  xml)! https://01.org/linuxgraphics/gfx-docs/drm/
- device register/unregister rework from Chris, with follow-up work from
  Benjamin. Allows more drivers to demidlayer load/unload and others to
  remove a bit of boilerplate.
- master/auth related cleanup, with docs
- some dma-buf polish, merged by Sumit
- small stuff all over (like build fixes from Arnd)

Group maintainership seems to slowly take off, with both Thierry and Sumit
pushing a few things. No hiccups thus far.

A bit bigger than I would normally like, but most of the large changes are
for polaris support and since polaris went upstream in 4.7, I'd like
to get the fixes in so it's in good shape when the hw becomes available.
The major changes only touch the polaris code so there is little chance
for regressions on other asics.  The rest are just the usual collection
of bug fixes.

that Display panel didn't work correctly when trigger mode was changed

For this, we keep trigger mode with SW trigger mode in default mode

However, we will need to consider PSR(Panel Self Reflash) mode to resolve
this issue fundamentally later.

0aae5920a8 drm: Clear up master tracking booleans
- is_master can be removed, we can compute this by checking allowed_master
  (which really just tracks whether a master struct has been allocated
  for this fpriv in either open or set_master), and whether the fpriv is
  the current master on the device.

- that frees up is_master as a good replacement name for allowed_master.
  With that it's clear that it tracks whether the fpriv is a master (with
  possibly clients attached to it and authenticated against it), and that
  one of those fprivs with is_master set is the current master.

v2: Fix kerneldoc for is_master (Emil).

a325725633 drm: Lobotomize set_busid nonsense for !pci drivers
We already have a fallback in place to fill out the unique from
dev->unique, which is set to something reasonable in drm_dev_alloc.

Which means we only need to have a special set_busid for pci devices,
to be able to care the backwards compat code for drm 1.1 around, which
libdrm still needs.

While developing and testing this patch things blew up in really
interesting ways, and the code is rather confusing in naming things
between the kernel code, ioctl #defines and libdrm. For the next brave
dragon slayer, document all this madness properly in the userspace
interface section of gpu.tmpl.

v2: Make drm_dev_set_unique static and update kerneldoc.

v3: Entire rewrite, plus document what's going on for posterity in the
gpu docbook uapi section.

v4: Drop accidental amdgpu hunk (Emil).

v5: Drop accidental omapdrm vblank counter change (Emil).

v6: Rebase on top of the sphinx conversion.

that for hilarity both the kernel-internal functions (set_busid) and

95c081c17f drm: Move master pointer from drm_minor to drm_device
There can only be one current master, and it's for the overall device.
Render/control minors don't support master-based auth at all.

This simplifies the master logic a lot, at least in my eyes: All these
additional pointer chases are just confusing.

While doing the conversion I spotted some locking fail:
- drm_lock/drm_auth check dev->master without holding the
  master_mutex. This is fallout from

  commit c996fd0b95
  Author: Thomas Hellstrom <thellstrom@vmware.com>
  Date:   Tue Feb 25 19:57:44 2014 +0100

      drm: Protect the master management with a drm_device::master_mutex v3

  but I honestly don't care one bit about those old legacy drivers
  using this.

- debugfs name info should just grab master_mutex.

- And the fbdev helper looked at it to figure out whether someone is
  using KMS. We just need a consistent value, so READ_ONCE. Aside: We
  should probably check if anyone has opened a control node too, but I
  guess current userspace doesn't really do that yet.

v2: Balance locking, reported by Julia.

v3: Rebase on top of Chris' oops fixes.

This will allow to convert driver .load() to

sti_compositor bring up 2 crtc but only one debugfs init is
needed so use drm_crtc_index to do it on the first one.
This can't be done in sti_drv because only sti_compositor have

It is almost the same for sti_encoder which handle multiple
encoder while one only debugfs entry is needed so add a boolean
to avoid multiple debugfs initialization

1e3fa0acfe drm/i915/fbc: Disable on HSW by default for now
>From https://bugs.freedesktop.org/show_bug.cgi?id=96461 :

This was kind of a difficult bug to track down. If you're using a
Haswell system running GNOME and you have fbc completely enabled and
working, playing videos can result in video artifacts. Steps to
reproduce:

- Run GNOME
- Ensure FBC is enabled and active
- Download a movie, I used the ogg version of Big Buck Bunny for this
- Run `gst-launch-1.0 filesrc location='some_movie.ogg' ! decodebin !
  glimagesink` in a terminal
- Watch for about over a minute, you'll see small horizontal lines go
  down the screen.

For the time being, disable FBC for Haswell by default.

Stefan Richter reported kernel freezes (no video artifacts) when fbc
is on.  (E3-1245 v3 with HD P4600; openbox and some KDE and LXDE
applications, thread begins at https://lkml.org/lkml/2016/4/26/813).
We also got reports from Steven Honeyman on openbox+roxterm.

v2 (From Paulo):
  - Add extra information to the commit message
  - Add Fixes tag
  - Rebase
