Pull drm fixes from Dave Airlie:
 "The main drm fixes pull for rc4: one regression fix in the connector
  refcounting, and an MST fix.

  There rest is nouveau, amdkfd, i915, etnaviv, and radeon/amdgpu fixes,
  mostly regression or black screen fixes"

drm/etnaviv: initialize iommu domain page size

2016-06-15T09:18:39+00:00

Since d16e0faab91 (iommu: Allow selecting page sizes per domain) the
iommu core demands the page size to be set per domain, otherwise any
mapping attempts will be dropped. Make sure to set a valid page size
for the etnaviv iommu.

drm/nouveau/Revert "drm/nouveau/device/pci: set as non-CPU-coherent on ARM64"

2016-06-15T06:16:13+00:00

This reverts commit 1733a2ad36741b1812cf8b3f3037c28d0af53f50.

There is apparently something amiss with the way the TTM code handles
DMA buffers, which the above commit was attempting to work around for
arm64 systems with non-coherent PCI. Unfortunately, this completely
breaks systems *with* coherent PCI (which appear to be the majority).

Booting a plain arm64 defconfig + CONFIG_DRM + CONFIG_DRM_NOUVEAU on
a machine with a PCI GPU having coherent dma_map_ops (in this case a
7600GT card plugged into an ARM Juno board) results in a fatal crash:

In a toss-up between the GPU seeing stale data artefacts on some systems
vs. catastrophic kernel crashes on other systems, the latter would seem
to take precedence, so revert this change until the real underlying
problem can be fixed.

2016-06-15T01:14:36+00:00

Not clearing mst manager's proposed vcpis table for destroyed connectors when the manager is stopped leaves it pointing to unrefernced memory, this causes pagefault when the manager is restarted when plugging back a branch.
