Sinclair Yeh 5858511646 drm/vmwgfx: Add support for imported Fence File Descriptor
This allows vmwgfx to wait on a fence created by another
device.

v2:
* Remove special handling for vmwgfx fence and just use dma_fence_wait()
* Use interruptible waits
* Added function documentation

Chris Wilson f54d186700 dma-buf: Rename struct fence to dma_fence
I plan to usurp the short name of struct fence for a core kernel struct,
and so I need to rename the specialised fence/timeline for DMA
operations to make room.

A consensus was reached in
https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html
that making clear this fence applies to DMA operations was a good thing.
Since then the patch has grown a bit as usage increases, so hopefully it
remains a good thing!

(v2...: rebase, rerun spatch)
v3: Compile on msm, spotted a manual fixup that I broke.
v4: Try again for msm, sorry Daniel

Daniel Vetter 1c0230de6d drm/vmwgfx: Nuke preclose hook
Again since the drm core takes care of event unlinking/disarming this
is now just needless code.

v2: I've completely missed eaction->fpriv_head and all the related
code. We need to nuke that too to avoid accidentally deferencing the
freed-up vmwgfx-private fpriv.

v3: Also remove vmw_fpriv->fence_events and unused variables I missed.

Thomas Hellstrom 6b82ef50d8 vmwgfx: Clean up pending event references to struct drm_file objects on close
Pending events may have stale pointer references to struct drm_file objects
after a file has been closed, but before the event is supposed to be
attached to the drm file. Remove such events on file close.

Tested with "modetest".

Add a way to send DRM events down the gpu fifo by attaching them to
fence objects. This may be useful for Xserver swapbuffer throttling and
page-flip done notifications.
