Probably a symptom of needing finer grained locking, but if we wait on
the incoming fence-fd (which could come from a different context) while
holding struct_mutex, that blocks retire_worker so gpu fences cannot get
signalled.

This causes a problem if userspace manages to get more than a frame
ahead, leaving the atomic-commit worker blocked waiting on fences that
cannot be signaled because submit is blocked waiting for a fence
signalled from vblank (after the atomic commit which is blocked).

If we start having multiple fence ctxs for the gpu, submit_fence_sync()
would probably need to move outside of struct_mutex as well.

In particular, attach() and unmap() need pm-runtime get/put to ensure
iommu clks are enabled.

Significantly simplifies things.  Also iommu_unmap() can unmap an entire
iova range.

(If backporting to downstream kernel you might need to revert this.  Or
at least double check older iommu implementation.)

A few more things for 4.12:
- ttm and amdgpu support for non-contiguous vram CPU mappings
- lots of bug fixes and cleanups for vega10
- misc bug fixes and code cleanups

[airlied: fix do_div error on 32-bit arm, not sure it's 100% correct]

* 'drm-next-4.12' of git://people.freedesktop.org/~agd5f/linux: (58 commits)
  drm/amdgpu: use uintptr_t instead of unsigned long to store pointer
  drm/amdgpu: Avoid using signed integer to store pointer value
  drm/amdgpu:invoke new implemented AI MB func
  drm/amdgpu/vega10:timeout set to equal with VI
  drm/amdgpu:implement the reset MB func for vega10
  drm/amdgpu:fix typo for mxgpu_ai
  drm/amdgpu:no need to involv HDP in KIQ
  drm/amdgpu:add PSP block only load_type=PSP (v2)
  drm/amdgpu/smu9: update to latest driver interface
  drm/amd/amdgpu: cleanup gfx_v9_0_gpu_init()
  drm/amd/amdgpu: cleanup gfx_v9_0_rlc_reset()
  drm/amd/amdgpu: cleanup gfx_v9_0_rlc_start()
  drm/amd/amdgpu: simplify gfx_v9_0_cp_gfx_enable()

  drm/amdgpu: Move function amdgpu_has_atpx near other similar functions
  ...

Highlights:
- Cooling device support from Russell, to allow GPU throttling on system
thermal overload.
- Explicit fencing support from Philipp, implemented in a similar way to
drm/msm.

* 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux:
  drm/etnaviv: submit support for out-fences
  drm/etnaviv: return GPU fence through the submit structure
  drm/etnaviv: submit support for in-fences
  drm/etnaviv: add etnaviv cooling device
  drm/etnaviv: switch to postclose
  drm/etnaviv: add lockdep assert to fence allocation

imx-drm module/dependency changes

- The PRE/PRG drivers added an unwanted DRM dependency to the ipu-v3 driver.
  Remove the dependency by conditionally disabling PRE/PRG support depending
  on CONFIG_DRM.
- Merge the imx-ipuv3-crtc module into the imxdrm module. There is no reason
  anymore for a separation between core drm driver and crtc/plane drivers,
  especially since commit eb8c8880 ("drm/imx: add deferred plane
  disabling"), which added a dependency on imx-ipuv3-crtc to the imxdrm
  module.

* tag 'imx-drm-next-2017-04-04' of git://git.pengutronix.de/git/pza/linux:
  drm/imx: merge imx-drm-core and ipuv3-crtc in one module
  gpu: ipu-v3: don't depend on DRM being enabled
