PSARC 2008/732 DRM IOCTL Addition for i915 Driver [Self Review]

[Frank Che]

The project team would like to add two more exported interfaces for this 
project, as described below. I think it's qualified for self review. 
Since this project hasn't been integrate into Nevada yet, I think it 
should be OK to just reply to this mail and add new information for 
recording purpose.

Two more exported interfaces:

------------------------------------------------------------------------------------------------- 

| Interface exported          | Classifications | 
Comments                                      |

| DRM_IOCTL_UPDATE_DRAW       | External        | Update drawable 
information.                  |
| DRM_IOCTL_I915_VBLANK_SWAP  | External        | Schedule buffer swap 
at given vertical blank. |
