Nouveau will need this on GeForce 8 and up to account for the GPU
reordering physical VRAM for some memory types.

It seems on some chipsets that doing this from the 0x20 handler causes the
display engine to not ever signal the final 0x40 stage.

This removes the previous prepare_access() and finish_access() hooks, and
replaces it with a much simpler flush() hook.
All the chipset-specific code before nv50 has its use removed completely,
as it's not required there at all.

The previous handler basically worked correctly for a full-blown mode
change. However, it did nothing at all when a partial (encoder only)
reconfiguation was necessary, leading to the display hanging on certain
types of mode switch.

Create connectors before encoders to avoid having to do another loop across
encoder list whenever we create a new connector. This allows us to pass
the connector to the encoder creation functions, and avoid using a
create_resources() callback since we can now call it directly.
This can also potentially modify the connector ordering on nv50. On cards
where the DCB connector and encoder tables are in the same order, things
will be unchanged. However, there's some cards where the ordering between
the tables differ, and in one case, leads us to naming the connectors
"wrongly".

After thinking it over a lot it made more sense for the core to deal with
the output polling especially so it can notify X.
v2: drop plans for fake connector - per Michel's comments - fix X patch sent to xorg-devel, add intel polled/hpd setting, add initial nouveau polled/hpd settings.
v3: add config lock take inside polling, add intel/nouveau poll init/fini calls
v4: config lock was a bit agressive, only needed around connector list reading.
otherwise it could re-enter.

* drm-fbdev-cleanup:
drm/fb: remove drm_fb_helper_setcolreg
drm/kms/fb: use slow work mechanism for normal hotplug also.
drm/kms/fb: add polling support for when nothing is connected.
drm/kms/fb: provide a 1024x768 fbcon if no outputs found.
drm/kms/fb: separate fbdev connector list from core drm connectors
drm/kms/fb: move to using fb helper crtc grouping instead of core crtc list
drm/fb: fix fbdev object model + cleanup properly.

As opposed to repeatedly reading the amount back from the GPU every
time we need to know the VRAM size.
We should now fail to load gracefully on detecting no VRAM, rather than
something potentially messy happening.

a) slow work is always used now for any fbcon hotplug, as its not
a fast task and is more suited to being ran under slow work.
b) attempt to not do any fbdev changes when X is running as we'll
just mess it up. This hooks set_par to hopefully do the changes
once X hands control to fbdev.
This also adds the nouveau/intel hotplug support.

The connector table index in the DCB entry for each output type is an
index into the connector table, and does *not* necessarily match up
with what was previously called "index" in the connector table entries
themselves.
Not real sure what that index is exactly, renamed to "index2" as we
still use it to prevent creating multiple TV connectors.

This makes this code common to both the nv04 and nv50 paths.
For the moment, we keep the previous behaviour with HDMI/eDP connectors
and report them as DVI-D/DP instead. This will be fixed once the rest
of the code has been fixed to deal with those types.

- Use driver level (0x2) for NV_DEBUG instead of all levels
- Create a NV_DEBUG_KMS for KMS level (0x4) and use them in modesetting code
- Remove a few odd NV_TRACE calls and replace some of them with NV_DEBUG_KMS or
NV_INFO

This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.
This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.
This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.
This driver is reverse engineered, and is in no way supported by nVidia.
Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.
This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.
