  drm/vmwgfx: Allow dropped masters render-node like access on legacy nodes v2

Merge branch 'exynos-drm-next' of git://git./linux/kernel/git/daeinki/drm-exynos into drm-next

   This is a last pull request, which includes two g2d patches
   I missed, and more cleanup series of Exynos drm driver.

   The cleanup series makes Exynos drm driver more simple,
   and removes unnecessary codes, and considers multiple plane format
   of framebuffer. I hope this not to be late.

drm/exynos: remove buf_cnt from struct exynos_drm_fb

Looking other drm drivers, there is no the restriction that framebuffer

If this limitation is removed, there is no reason keeping buffer count

drm/exynos: add macro to get the address of START_S reg

This macro is need to get the value of the START shadow register, that
will tell if an framebuffer is currently displayed on the screen or not.

drm/exynos: check for pending fb before finish update

The current code was ignoring the end of update for all overlay planes,
caring only for the primary plane update in case of pageflip.

This change adds a change to start to check for pending updates for all
planes through exynos_plane->pending_fb. At the start of plane update the
pending_fb is set with the fb to be shown on the screen. Then only when to
fb is already presented in the screen we set pending_fb to NULL to
signal that the update was finished.

drm/exynos: add prepare and cleanup phases for planes

From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

.prepare_plane() and .cleanup_plane() allows to perform extra operations
before and after the update of planes. For FIMD for example this will
be used to enable disable the shadow protection bit.

Merge branch 'linux-4.3' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next

Rather large pull request this time around, due to the long-pending
cleanup of the kernel driver being here.  There's a stupidly large
number of commits for that, as I wanted to have the series be
bisectable at a fairly fine-grained level.  That said, a very large
portion of the churn in the rework was automated, and a very large
number of boards from right across the whole range we support have
been tested.  I'm fairly confident there shouldn't be (too many)
issues from this.

Beyond correcting some not-so-great design decisions and making the
code a lot easier to work with, there's not much exciting (lower
memory usage, GPU VM should be a lot faster, etc) to be gained by the
end-user as a result of the cleanup, it mostly lays the groundwork for
future improvements.

A big thanks goes to Alexandre Courbot for testing/debugging the GK20A
codepaths for me :)

Highlights:
- A heap of perfmon work, providing a more useful userspace interface
and specifying counters for a bunch of boards
- Support for GT200 reclocking + other misc pm improvements
- Initial patches towards supporting GM20B (Tegra X1)
- Maxwell DisplayPort fixes
- Cleanup of the kernel driver
- The usual collection of random fixes
