Subject: [PATCH 02/11] vmwgfx: Avoid HW operations when not master

Note that for DRI2, a dri2_copy_region becomes a NOP when not master.
Additionally, all dri2 operations that lead to a potential kernel
access will return FALSE.

Subject: [PATCH 03/11] vmwgfx: Implement textured video completely on top of
 XA.

Remove device-specific hacks. This may increase resource usage a little
on old hardware revisions, but we don't need separate code paths on
different hardware revisions.

Subject: [PATCH 07/11] vmwgfx: Support also XA version 1 v2

We need to support also XA version 1, since we want to be backwards
compatible with older mesa releases.
Unfortunately, the intended way of detecting XA major version at
compile-time was broken on mesa 10 so we need a workaround that tests
for XA version 2 at config time.

v2: Update the test for XA version 2.

Subject: [PATCH 09/11] Revert "vmwgfx: Get rid of device-specific DMA code"

This reverts commit 45b2457516a9db4bd1d60fbb24a1efbe2d9dd932.

Reverting this because using direct DMA for shared pixmaps should
boost performance. It should be usable both in a composited environment
and when running hosted. Need to retest the DMA flaws I saw before disabling
this code.
