[Mesa-stable] Nomination of a patch series for stable (virgl/performance)

[Gert Wollny]

Hello, 

I'd like to nominate the following three patches for stable:

c0773315af76cd735152c322cb7f710b4b053148
   virgl: quadruple command
buffer size
d18492c64f0abb4eb638d2b213b4b1ff3d775965
   virgl: avoid large inline transfers
89b4798c0619a2ba99046d5ad36f0e6851625f7a 
   virgl: don't mark buffers as unclean after a write

These patches improve 3D performance for virgl users significantly. The
following numbers were measured running Qemu with virgl on top of a
r600 (AMD 6870 HD) host:

## Unigine Valley (1024x768, Q:High, AA:2x)

        | FPS avrg |  Score  
--------------------------------
before  |   8.2    |   343
after   |  21.9    |   916

## Unigine Heaven (1024x768, Q:High, Tess: Disabled, AA:2x) 

        | FPS avrg |  Score  
--------------------------------
before  | 
13.2    |   333
after   |  32.3    |   790


many thanks,
