Merge tag 'drm-next-2018-10-24' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie:
"This is going to rebuild more than drm as it adds a new helper to
list.h for doing bulk updates. Seemed like a reasonable addition to
me.
Otherwise the usual merge window stuff lots of i915 and amdgpu, not so
much nouveau, and piles of everything else.
Core:
- Adds a new list.h helper for doing bulk list updates for TTM.
- Don't leak fb address in smem_start to userspace (comes with EXPORT
workaround for people using mali out of tree hacks)
- udmabuf device to turn memfd regions into dma-buf
- Per-plane blend mode property
- ref/unref replacements with get/put
- fbdev conflicting framebuffers code cleaned up
- host-endian format variants
- panel orientation quirk for Acer One 10
bridge:
- TI SN65DSI86 chip support
vkms:
- GEM support.
- Cursor support

- xGMI support
- DC i2c/aux cleanup
- Ycbcr 4:2:0 support
- GPUVM improvements
- Powerplay and powerplay endian fixes
- Display underflow fixes

qxl:
- use more helpers
i915:
- GGTT coherency getparam
- Turn off resource streamer API
- More Icelake enablement + DMC firmware
- Full PPGTT for Ivybridge, Haswell and Valleyview
- DDB distribution based on resolution
- Limited range DP display support
nouveau:
- CEC over DP AUX support
- Initial HDMI 2.0 support
virtio-gpu:
- vmap support for PRIME objects
tegra:
