[Mesa-dev] [PATCH 0/4] GBM map/unmap support

[Rob Herring]

This series adds map and unmap functions to GBM. These are needed to 
provide a device independent buffer allocation interface to Android's 
gralloc.

Major changes from RFC[1]:
- Split up patches
- Consistently use map instead of lock for function names
- Clean up and propogate mapping usage flags
- Add extension version checking
- Add returned stride for mapped buffer
- Got rid of pipe_private ptr passing it back to caller instead
- Move context creation to gbm_device_create and add destroyContext call
- Add/fix function comments

Open questions:
- Is creating a context internally in GBM okay? Does it need special 
  flags for context creation? 
- Need to flush context on unmap?
- Need fences for gralloc lockAsync support?
