Dave, Daniel,

A couple of fixes for vmwgfx. Two fixes for a DMA sg-list debug warning
message. These are not cc'd stable since there is no evidence of actual
breakage.
On fix for the high-bandwidth backdoor port which is cc'd stable due to
upcoming hardware, on which the code would otherwise break.

The following changes since commit 5ed7f4b5eca11c3c69e7c8b53e4321812bc1ee1e:

  drm/vmwgfx: integer underflow in vmw_cmd_dx_set_shader() leading to an invalid read (2019-05-21 10:23:10 +0200)
