Merge tag 'drm-fixes-for-v4.10-rc6' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "drm fixes across the board.

  Okay holidays and LCA kinda caught up with me, I thought I'd get some
  of this dequeued last week, but Hobart was sunny and warm and not all
  gloomy and rainy as usual.

  This is a bit large, but not too much considering it's two weeks stuff
  from AMD and Intel.

  core:
   - one locking fix that helps with dynamic suspend/resume races

  i915:
   - mostly GVT updates, GVT was a recent introduction so fixes for it
     shouldn't cause any notable side effects.

  amdgpu:
   - a bunch of fixes for GPUs with a different memory controller design
     that need different firmware.

  exynos:
   - decon regression fixes

  msm:
   - two regression fixes

  etnaviv:
   - a workaround for an mmu bug that needs a lot more work.

  virtio:
   - sparse fix, and a maintainers update"

This is a KMS driver for emulated cirrus device in qemu.
It is *NOT* intended for real cirrus devices. This requires
the modesetting userspace X.org driver.
Cirrus is obsolete, the hardware was designed in the 90ies
and can't keep up with todays needs. More background:
https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered-harmful/
Better alternatives are:
- stdvga (DRM_BOCHS, qemu -vga std, default in qemu 2.2+)
- qxl (DRM_QXL, qemu -vga qxl, works best with spice)
- virtio (DRM_VIRTIO_GPU), qemu -vga virtio)

* @vgpu: virtual GPU
* @dmlr: vGPU Device Model Level Reset or GT Reset
* @engine_mask: engines to reset for GT reset
*
* This function is called when user wants to reset a virtual GPU through
* device model reset or GT reset. The caller should hold the gvt lock.
*
* vGPU Device Model Level Reset (DMLR) simulates the PCI level reset to reset
* the whole vGPU to default state as when it is created. This vGPU function
* is required both for functionary and security concerns.The ultimate goal
* of vGPU FLR is that reuse a vGPU instance by virtual machines. When we
* assign a vGPU to a virtual machine we must isse such reset first.
*
* Full GT Reset and Per-Engine GT Reset are soft reset flow for GPU engines
* (Render, Blitter, Video, Video Enhancement). It is defined by GPU Spec.
* Unlike the FLR, GT reset only reset particular resource of a vGPU per
* the reset request. Guest driver can issue a GT reset by programming the
* virtual GDRST register to reset specific virtual GPU engine or all
* engines.
*
* The parameter dev_level is to identify if we will do DMLR or GT reset.
* The parameter engine_mask is to specific the engines that need to be
* resetted. If value ALL_ENGINES is given for engine_mask, it means
* the caller requests a full GT reset that we will reset all virtual
* GPU engines. For FLR, engine_mask is ignored.
