The core takes care of handling the send_event vs. close() issues, we
can remove that driver code.

I didn't spot anything that would require ordering here (well not
anywhere else either), and I'm trying to unify at least modern drivers
on one close hook.

The newly added a5xx support fails to build when debugfs is diabled:

drivers/gpu/drm/msm/adreno/a5xx_gpu.c:849:4: error: 'struct msm_gpu_funcs' has no member named 'show'
drivers/gpu/drm/msm/adreno/a5xx_gpu.c:849:11: error: 'a5xx_show' undeclared here (not in a function); did you mean 'a5xx_irq'?

This adds a missing #ifdef.

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

Signed-off-by: Rob Clark <robdclark@gmail.com>

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

  ...

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
