Many drivers (21 to be exact) create connectors that are always
connected (for instance to an LVDS or DSI panel). Instead of forcing
them to implement a dummy .detect() handler, make the callback optional
and consider the connector as always connected in that case.

This fixes a regression in all these drivers since the cache
mode tracking was fixed for mixed mappings. It uses the new
arch API to add the VRAM range to the PAT mapping tracking
tables.

Lots of drivers don't properly compile without this when CONFIG_FB=n.
It's kinda a hack, but since CONFIG_FB doesn't stub any fucntions when
it's disabled I think it makes sense to add it to drm_fb_helper.h.
Long term we probably need to rethink all the logic to unload firmware
framebuffer drivers, at least if we want to be able to move away from
CONFIG_FB and fbcon.
v2: Unfortunately just stubbing out remove_conflicting_framebuffers in
drm_fb_helper.h upset gcc about static vs. non-static declarations, so
a new wrapper it needs to be. Means more churn :(

drm_gem_object_unreference_unlocked()

git://anongit.freedesktop.org/drm-intel into drm-next
As promised, piles of prep work all around:
- drm_atomic_state rework, prep for nonblocking commit helpers
- fence patches from Gustavo and Christian to prep for atomic fences and
some cool work in ttm/amdgpu from Christian
- drm event prep for both nonblocking commit and atomic fences
- Gustavo seems on a crusade against the non-kms-native version of the
vblank functions.
- prep work from Boris to nuke all the silly ->best_encoder
implementations we have (we really only need that for truly dynamic
cases like dvi-i vs dvi-d or dp mst selecting the right transcoder on
intel)
- prep work from Laurent to rework the format handling functions
- and few small things all over

Change return value to int to propagate errors from gamma_set,
and remove start parameter. Updates always use the full size,
and some drivers even ignore the start parameter altogether.
This is needed for atomic drivers, where an atomic commit can
fail with -EINTR or -ENOMEM and should be restarted. This is already
and issue for drm_atomic_helper_legacy_set_gamma, which this patch
fixes up.
Changes since v1:
- Fix compiler warning. (Emil)
- Fix commit message (Daniel)

This allows us to ditch a ton of ugly #ifdefs from a bunch of drm modeset
drivers.
v2: Make the dummy function actually return a sane value, spotted by

v3: Because the patch is still in limbo there's no more drivers to
convert, noticed by Emil.
v4: Rebase once more, because hooray. I'll just go ahead an apply this
one later on to drm-misc.

The cursor code may be entered with file_priv == NULL && handle == NULL.
The problem was introduced by:
"bf89209 drm/mga200g: Hold a proper reference for cursor_set"
which calls drm_gem_object_lookup(dev, file_priv...). Previously this wasn't
a problem because we checked the handle. Move the check early in the function
can fix the problem.

mgag200_driver_load's error path just calls the drm driver's
driver_unload op. It isn't safe to call this because it doesn't handle
things well if driver_load fails somewhere mid way.
Replace the call to mgag200_driver_unload with a more finegrained
error handling path.

calling mga_fbdev_destroy.

Looking up an obj, immediate dropping the acquired reference and then
continuing to use it isn't how this is supposed to work. Fix this by
holding a reference for the entire function.
While at it stop grabbing dev->struct_mutex, it doesn't protect
anything here.

Since David Herrmann's mmap vma manager rework we don't need to grab
dev->struct_mutex any more to prevent races when looking up the mmap
offset. Drop it and instead don't forget to use the unref_unlocked
variant (since the drm core still cares).

Make drm_fb_helper_initial_config() return an int rather than a bool so
that the error can be properly propagated. While at it, update drivers
to propagate errors further rather than just ignore them.
v2:
- cirrus: No cleanup is required, the top-level cirrus_driver_load()
will do it as part of cirrus_driver_unload() in its cleanup path.

Just a bit of OCD cleanup on headers - this function isn't the core
interface any more but just a helper for drivers who haven't yet
transitioned to universal planes. Put the declaration at the right
spot and sprinkle necessary #includes over all drivers.
Maybe this helps to encourage driver maintainers to do the switch.
v2: Fix #include ordering for tegra, reported by 0-day builder.
v3: Include required headers, reported by Thierry.

- i915 still uses the legacy pci dma alloc api, so grows an include.
Everything else fairly standard.
