Pull drm fixes from Dave Airlie:
 "Misc fixes for v4.11-rc1.

  This is a selection of fixes for recent bugs, the vmwgfx one is
  important to avoid a regression, and compat ioctl one is pretty urgent
  for stable. Otherwise nothing too much.

  I've got a separate pull req for some AST hw IBM need to enable"
