6ef4ead1b2 drm/nouveau/bios: log if auxch accesses fail, also return 0x00 from rd when it does
Logging at trace level, rather than as en error, as it seems conceivable
that failure could be normal under certain circumstances (new bios,
older sink that doesn't support a particular DPCD address)

ba6e34e612 drm/gm204/devinit: initial implementation
Starting from GM204, certain registers are no longer accessible by the host
(or unsigned PMU firmware).

This commit implements devinit on PMU, using a signed microcode image, and
devinit data, from the VBIOS.

ad4a362635 drm/nouveau/bios: split out shadow methods
We're about to need to be able to fetch additional chunks of data beyond
the primary bios image, which makes fetching a lot more complicated.

This splits out the verious shadowing routines to be nothing more than
very dumb "fetch this much data from this offset" routines, and leaves
the logic of what and how much to fetch in common code.

355a701838 drm/gem: Warn on illegal use of the dumb buffer interface v2
It happens on occasion that developers of generic user-space applications
abuse the dumb buffer API to get hold of drm buffers that they can both
mmap() and use for GPU acceleration, using the assumptions that dumb buffers
and buffers available for GPU are
a) The same type and can be aribtrarily type-casted.
b) fully coherent.

This patch makes the most widely used drivers warn nicely when that happens,
the next step will be to fail.

v2: Move drmP.h changes to drm_gem.h. Fix Radeon dumb mmap breakage.

3cb9ae4fd8 drm: Move drm_crtc_init from drm_crtc.h to drm_plane_helper.h
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.

40ac948e02 drm/gt215/gr: fix initialisation on gddr5 boards
The binary driver modifies the default context to have this value, rather
than 0x3d0040, *after* it's filled the buffer with the usual golden data.

We don't really have anything in place to locate the correct offset to do
these type of modifications outside of the generation function, so this
will have to do.

6fbb702e27 drm/nouveau: make sure display hardware is reinitialised on runtime resume
Linus commit 05c63c2ff2 modified the
runtime suspend/resume paths to skip over display-related tasks to
avoid locking issues on resume.

Unfortunately, this resulted in the display hardware being left in
a partially initialised state, preventing subsequent modesets from
completing.

This commit unifies the (many) suspend/resume paths, bringing back
display (and fbcon) handling in the runtime paths.

634ffcccfb drm/nouveau: punt fbcon resume out to a workqueue
Preparation for some runtime pm fixes.  Currently we skip over fbcon
suspend/resume in the runtime path, which causes issues on resume if
fbcon tries to write to the framebuffer before the BAR subdev has
been resumed to restore the BAR1 VM setup.

As we might be woken up via a sysfs connector, we are unable to call
fb_set_suspend() in the resume path as it could make its way down to
a modeset and cause all sorts of locking hilarity.

To solve this, we'll just delay the fbcon resume to a workqueue.

f2f9a2cbaf drm/nouveau: fix regression on original nv50 board
Xorg (and any non-DRM client really) doesn't have permission to directly
touch VRAM on nv50 and up, which the fence code prior to g84 depends on.

It's less invasive to temporarily grant it premission to do so, as it
previously did, than it is to rework fencenv50 to use the VM.  That
will come later on.

1dadba87cb drm/nouveau: nv84+: fix fence context seqno's
This fixes a regression introduced by "drm/nouveau: rework to new fence interface"
(commit 29ba89b237).

The fence sequence should not be reset after creation, the old value is used instead.
On destruction the final value is written, to prevent another source of accidental
wraparound in case of a channel being destroyed after a hang, and unblocking any other
channel that may wait on the about-to-be-deleted channel to signal.

I'm nothing if not optimistic about any hope of recovery from that. ;-)

f91ce35e47 ACPIPHP / radeon / nouveau: Remove acpi_bus_no_hotplug()
Revert parts of f244d8b623 ("ACPIPHP / radeon / nouveau: Fix VGA
switcheroo problem related to hotplug").

A previous commit 5493b31f0b55 ("PCI: Add pci_ignore_hotplug() to ignore
hotplug events for a device") added equivalent functionality implemented in
a different way for both acpiphp and pciehp.
