It apparently blows up on some machines.

drm/radeon: fix runtime suspend breaking secondary GPUs

2014-03-28T02:27:25Z

Same fix as for nouveau, when we fail with EINVAL, subsequent gets fail hard, causing the device not to open. Signed-off-by: Dave Airlie Reviewed-by: Alex Deucher

drm/nouveau: fail runtime pm properly.

2014-03-27T02:20:37Z

If we were on a non-optimus device, we'd return -EINVAL, this would lead to the over engineered runtime pm system to go into an error state, subsequent get_sync's would fail, so we'd never be able to open the device again. (like really get_sync shouldn't fail if the device isn't powered down). Signed-off-by: Dave Airlie Reviewed-by: Alex Deucher

drm/udl: take reference to device struct for dma-bufs

2014-03-27T02:19:50Z

this stops the device from being deleted before all the dma-bufs on it are freed, this fixes an oops when you unplug a udl device while it has imported a buffer from another device. Signed-off-by: Dave Airlie

drm/i915: Disable stolen memory when DMAR is active

2014-03-19T08:05:38Z

We have reports of heavy screen corruption if we try to use the stolen memory reserved by the BIOS whilst the DMA-Remapper is active. This quirk may be only specific to a few machines or BIOSes, but first lets apply the big hammer and always disable use of stolen memory when DMAR is active. v2 by Jani: Rebase on -fixes, only look at intel_iommu_gfx_mapped.
