drm/probe-helper: clamp unknown connector status in the poll work
On some chipset we try to avoid possibly invasive output detection
methods (like load detect which can cause flickering elsewhere) in the
output poll work. Drivers could hence return unknown when a previous
full ->detect call returned a different state.
This change will generate a hotplug event, forcing userspace to do a
full scan. This in turn updates the connector->status field so that we
will _again_ get a state change when the hotplug work re-runs in 10
seconds.
To avoid this ping-pong loop detect this situation and clamp the
connector state to the old value.
Patch is inspired by a patch from Knut Peterson. Knut's patch
completely ignored connector state changes if either the old or new
status was unknown, which seemed to be a bit too agressive to me.
v2: Rebased onto the drm_probe_helper.c extraction.

drm/probe-helper: don't lose hotplug event
There's a race window (small for hpd, 10s large for polled outputs)
where userspace could sneak in with an unrelated connnector probe
ioctl call and eat the hotplug event (since neither the hpd nor the
poll code see a state change).
To avoid this, check whether the connector state changes in all other
->detect calls (in the current helper code that's only probe_single)
and if that's the case, fire off a hotplug event. Note that we can't
directly call the hotplug event handler, since that expects that no
locks are held (due to reentrancy with the fb code to update the kms
console).
Also, this requires that drivers using the probe_single helper
function set up the poll work. All current drivers do that already,
and with the reworked hpd handling there'll be no downside to
unconditionally setting up the poll work any more.
v2: Review from Rob Clark
- Don't bail out of the output poll work immediately if it's disabled
to make sure we deliver the delayed hoptplug events. Instead just
jump to the tail.
- Don't scheduel the work when it's not set up. Would be a driver bug
since using probe helpers for anything dynamic without them
initialized makes them all noops.

Merge branch 'linux-3.20' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
There's a huge amount of no-op churn here renaming the majority of the
driver from nouveau_ to nvkm_, in preparation for splitting the module
into two down the track. Also switched to NVIDIA's unit and chipset
names at the same time. Despite the massive amount of code touch, the
commits should be safe as objdump was used to verify nothing got
changed accidentally in the renames.
Aside from that, not much in this first pull request:
- nouveau_platform.ko for GK20A was merged into nouveau.ko
- GK20A dynamic reclocking support
- no more vt-switches across suspend/resume
- changed output scaling policy. if the mode comes from the display's
edid, we program that directly rather than using the gpu to scale to
the panel's native mode. this should address complaints of having to
jump through hoops for 24/120Hz modes etc
- various other minor fixups and cleanups

drm/nouveau: finalise nvkm namespace switch (no binary change)
The namespace of NVKM is being changed to nvkm_ instead of nouveau_,

done in order to make it very clear as to what part of the driver a

Because there's already a large amount of churn here anyway, this is

The [ SUBDEV] specified in log output will be a bit different for

the object (so, up object.parent somewhere).
Later patches will append object and class identifiers to messages,

includes separating modules into ASIC-specific functionality, adding
new properties that are relevant for VI, making sure that shared code is
reused, etc.
- Improve mechanism of submitting packets to HIQ (the kernel queue that amdkfd
uses to issue commands to the GPU). The driver used to verify that each CS
was read by the GPU. However, this proved to be both unnecessary and erroneous.
Therefore, we cancelled this verification.

I was not able to reproduce this problem, as it seems that -m32 works
fine for my cross compiler gcc 4.6.3, but I have to assume that -m32
was deprecated somewhere between 4.6 and 4.8. As it still seems to

drm: Make drm_read() more robust against multithreaded races
The current implementation of drm_read() faces a number of issues:
1. Upon an error, it consumes the event which may lead to the client
blocking.
2. Upon an error, it forgets about events already copied
3. If it fails to copy a single event with O_NONBLOCK it falls into a
infinite loop of reporting EAGAIN.
3. There is a race between multiple waiters and blocking reads of the
events list.
Here, we inline drm_dequeue_event() into drm_read() so that we can take
the spinlock around the list walking and event copying, and importantly
reorder the error handling to avoid the issues above.
