a55b68e06b drm/nv50/disp: silence compiler warning
NFI why this only started appearing now.  The use of the uninitialised var
can't actually happen, so perhaps my compiler just got stupider.

60f60bf1bc drm/nv50-nvc0: request and wait on notification of modeset completion
This should prevent a number of races from occuring, the most obvious of
which will be exposed when we start making use of the "display sync" evo
channel for page flipping.  The DS channel will reject any command stream
that doesn't completely agree with the current "master" state.

f13e435c59 drm/nv50-nvc0: switch to tasklet for display isr bh
We need to be able to have the bh run while possibly spinning waiting for
the EVO notifier to signal.  This apparently happens in some circumstances
with preempt disabled, so our workqueue was never being run.

d82f8e6c80 drm/nouveau: use system_wq instead of dev_priv->wq
With cmwq, there's no reason for nouveau to use a dedicated workqueue.
Drop dev_priv->wq and use system_wq instead.  Each work item is sync
flushed when the containing structure is unregistered/destroyed.

Note that this change also makes sure that nv50_gpio_handler is not
freed while the contained work item is still running.

fce2bad0ee drm/nv50: rework PGPIO IRQ handling and hotplug detection
Allows callers to install their own handlers for when a GPIO line
changes state (such as for hotplug detect).

This also fixes a bug where we weren't acknowledging the GPIO IRQ
until after the bottom half had run, causing a severe IRQ storm
in some cases.

1f6d2de2c5 drm/nv50: Keep track of the head a channel is vsync'ing to.
In a multihead setup vblank interrupts may end up enabled in both
heads. In that case we want to ignore the vblank interrupts coming
from the wrong CRTC to avoid tearing and unbalanced calls to
drm_vblank_get/put (fdo bug 31074).

8f1a60868f drm/nouveau: tidy connector/encoder creation a little
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".

eb1f8e4f3b drm/fbdev: rework output polling to be back in the core. (v4)
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.
