Pandoc really did a bad job of converting the big KMS properties table
to RST. Instead, put the properties into a separate plain text CSV file,
and include it in the RST file. The generated output isn't very pretty,
but at least the information is there, and it's stored in a format
that's easier to process and improve upon at a later time.
The CSV file was generated by copy-pasting the table from the HTML
generated by the DocBook toolchain into LibreOffice Calc, and then saved
as CSV, unmodified.

While splitting the document up, the headings "shifted" from what pandoc
generated. Use the following order for headings for consistency:
==============
Document title
==============
First
=====
Second
------
Third
~~~~~
Leave the lower level headings as they are; I think those are less
important. Although RST doesn't mandate a specific order ("Rather than
imposing a fixed number and order of section title adornment styles, the
order enforced will be the order as encountered."), having the higher
levels the same overall makes it easier to follow the documents.
[I'm sort of kind of writing the recommendation for docs-next in the
mean time, but this order seems sensible, and is what I'm proposing.]

This is the first step towards converting the DocBook gpu.tmpl to Sphinx
and reStructuredText, the new kernel documentation tool and markup.
Use Jon's "cheesy conversion script" in Documentation/sphinx/tmplcvt to
do the rough conversion. Do the manual edits in follow-up patches. Add a
new Documentation/gpu directories for the graphics related
documentation. (Hooray, now we can have directories based on topics
rather than tools under Documentation.)
We also won't remove the DocBook gpu.tmpl yet so it's easier to build
both and compare the results for parity.

Currently the driver calls drm_dev_register() directly after allocating
the DRM device and then continues with further initialization. This is
incorrect, because drm_dev_register() is supposed to be called after all
initialization is done. This problem was masked by the fact that
drm_dev_register() did not use to do anything special before, but
recently it started to call drm_connector_register_all(), which leads to
a crash if the driver is not fully initialized.
This patch fixes the problem by moving the call to drm_dev_register() to
the end of the initialization sequence and also removing the, now
unnecessary, call to drm_connector_register_all() from driver code.

Simplifies cleanup, and there's no reason drivers should ever care
about authmagic at all - it's all handled in the core.
And with that, Ladies and Gentlemen, it's time to pop the champagen
and celebrate: dev->struct_mutex is now officially gone from modern
drivers, and if a driver is using gem_free_object_unlocked and doesn't
do anything else silly it's positively impossible to ever touch
dev->struct_mutex at runtime, anywhere.
Well except for the mutex_init on driver load ;-)

It's related, and soon authmagic will also use the master_mutex.
There is an ever-so-slightly semantic change here:
- authmagic will only be cleaned up for primary_client drm_minors. But
it's impossible to create authmagic on render/control nodes, so this
is fine.
- The cleanup is moved down a bit in the release processing. Doesn't
matter at all since authmagic is purely internal logic used by the
core ioctl access checks, and when we're in a file's release
callback no one can do ioctls any more.

The callback function dma_buf_describe() returns an int not void so the
function pointer cast in dma_buf_show() is wrong. dma_buf_describe() can
also fail when acquiring the mutex gets interrupted so always returning
0 in dma_buf_show() is wrong, too.
Fix both issues by avoiding the indirection via dma_buf_show() and call
dma_buf_describe() directly. Rename it to dma_buf_debug_show() to get it
in line with the other functions.
This type mismatch was caught by the PaX RAP plugin.

The drm_dp_aux is associated with the intel_dp encoder and not the
connector. Since the encoder is destroyed before the connector,
attempting to free the drm_dp_aux from inside the connector cleanup
causes a use-after-free.
This was applied to the patch that CI was happy with, but in the
confusion of so many series trying to make CI happy, the unready
patch was plucked.

not be part of the kernel, causing the link to fail:

A few things:
- Rename the cleanup function from drm_master_release to
drm_legacy_lock_release. It doesn't relase any master stuff, but
just the legacy hw lock.
- Hide it in drm_lock.c, which allows us to make a few more functions
static in there. To avoid forward decl we need to shuffle the code a
bit though.
- Push the check for ->master into the function itself.
- Only call this for !DRIVER_MODESET.
End result: Another place that takes struct_mutex gone for good for
modern drivers.
v2: Remove leftover comment.

- best_encoder cleanup from Boris.
- drm_simple_display_pipe helpers from Noralf. Looks really neat imo, and
there's 2-3 in-flight drivers which look like they could/should use it.
Anyway, with this we have now helpers and everything in place to write
drivers for simple hw with fewer complexity in the driver than what
fbdev would need. That was the last complaint I've heard from embedded
folks after we made atomic happen. Mission accomplished!
- nonblocking commit helpers for atomic, plus a bunch of driver patches
for that.
- Prep patch from Laurent for cleaned up pixel format functions.
- More of Gustavo's cleanup for drm vblank functions.
- and a few oddball things in between
Plus the merge of docs-next to prep the docbook->sphinx conversion as
discussed. Jon cc'ed as fyi.
