[git pull] vmwgfx-next

[Thomas Hellstrom]

Hi, Dave

I realize this is probably too late for the next merge window. If that's the case, then
we can just postpone it for 4.21.

Mostly code reorganizations and optimizations for vmwgfx.
- Move TTM code that's only used by vmwgfx to vmwgfx
- Break out the vmwgfx buffer- and resource validation code to a separate source file
- Get rid of a number of atomic operations during command buffer validation.

The following changes since commit 36c9c3c91128e2b892c9be0dd9ee9bd82cbe82ad:

  Merge branch 'drm-next-4.20' of git://people.freedesktop.org/~agd5f/linux into drm-next (2018-09-21 09:52:53 +1000)
