Merge branch 'vmwgfx-fixes-4.15' of git://people.freedesktop.org/~thomash/linux into drm-fixes

Two important fixes for vmwgfx.
The off-by-one fix could cause a malicious user to potentially crash the
kernel.
The framebuffer map cache fix can under some circumstances enable a user to
read from or write to freed pages.

* 'vmwgfx-fixes-4.15' of git://people.freedesktop.org/~thomash/linux:
  drm/vmwgfx: Potential off by one in vmw_view_add()
  drm/vmwgfx: Don't cache framebuffer maps
