2012-08-17drm/i915: Haswell HDMI audio initializationWang Xingchao
Added new haswell_write_eld() to initialize Haswell HDMI audio registers to generate an unsolicited response to the audio controller driver to indicate that the controller sequence should start.

2012-08-17drm/i915: implement dma buf begin_cpu_access (v2)Dave Airlie
In order for udl vmap to work properly, we need to push the object into the CPU domain before we start copying the data to the USB device. This along with the udl change avoids userspace explicit mapping to be used. v2: add a flag for userspace to query to know if Intel kernel driver can deal with the vmap flushing properly. In theory udl would need a flag also, but I intend to push the patches very close to each other and other drivers should do the right thing from the start. I've added a test to my intel-gpu-tools prime branch, however testing this is a bit messy since the only way to get udl to vmap is to rendering something. I've tested this with real code as well to make sure it works.

2012-08-17drm/fb-helper: don't clobber output routing in setup_crtcsDaniel Vetter
Yet again the too close relationship between the fb helper and the crtc helper code strikes. This time around the fb helper resets all encoder->crtc pointers to NULL before starting to set up it's own mode. Which is total bullocks, because this will clobber the existing output routing, which the new drm/i915 code depends upon to be absolutely correct. The crtc helper itself doesn't really care about that, since it disables unused encoders in a rather roundabout way anyway. Two places call drm_setup_crts: - For the initial fb config. I've auditted all current drivers, and they all allocate their encoders with kzalloc. So there's no need to clear encoder->crtc once more. - When processing hotplug events while showing the fb console. This one is a bit more tricky, but both the crtc helper code and the new drm/i915 modeset code disable encoders if their crtc is changed and that encoder isn't part of the new config. Also, both disable any disconnected outputs, too. Which only leaves encoders that are on, connected, but for some odd reason the fb helper code doesn't want to use. That would be a bug in the fb configuration selector, since it tries to light up as many outputs as possible. v2: Kill the now unused encoders variable.

2012-08-17drm/i915: simplify dvo dpms interfaceDaniel Vetter
All dvo drivers only support 2 dpms states, and our dvo driver even switches of the dvo port for anything else than DPMS_ON. Hence ditch this complexity and simply use bool enable. While reading through this code I've noticed that the mode_set function of ch7017 is a bit peculiar - it disable the lvds again, even though the crtc helper code should have done that ... This might be to work around an issue at driver load, we pretty much ignore the hw state when taking over. v2: Also do the conversion for the new ns2501 driver.

2012-08-17drm/i915: prepare load-detect pipe code for dpms changesDaniel Vetter
A few things need adjustement: - Change the dpms state by calling the dpms connector function and not some crtc helper internal callbacks. Otherwise this will break once we switch to our own dpms handling. - Instead of tracking and restoring intel_crtc->dpms_mode use the connector's dpms variable - the former relies on the dpms compuation rules used by the crtc helper. And it would break when the encoder is cloned and the other output has a different dpms state. But luckily no one is crazy enough for that. - Properly clear the connector -> encoder -> crtc linking, even when failing (note that the crtc helper removes the encoder -> crtc link in disabled_unused_functions for us).

We drop packet unconditionally when we fail to mirror it. This is not intended in some cases. Consdier for kvm guest, we may mirror the traffic of the bridge to a tap device used by a VM. When kernel fails to mirror the packet in conditions such as when qemu crashes or stop polling the tap, it's hard for the management software to detect such condition and clean the the mirroring before. This would lead all packets to the bridge to be dropped and break the netowrk of other virtual machines.

To work around this, I've renamed the modules to "nfsv2.ko" "nfsv3.ko" and "nfsv4.ko". I also had to move the nfs4_fs_type back to nfs.ko to ensure that `mount -t nfs4` still works.

2012-08-16staging:iio:ad7780: Mark channels as unsignedLars-Peter Clausen
The values reported by the AD7780 are unsigned with a binary offset: 0x000000 is negative fullscale 0x800000 is zeroscale 0xffffff is positive fullscale So mark the channel in the channel spec as unsigned rather than signed.
