[PATCH 0/6] dma-buf synchronization patches (updated)

[Maarten Lankhorst]

The following series implements fence and converts dma-buf and
android sync to use it. Patch 5 and 6 add support for polling
to dma-buf, blocking until all fences are signaled.

Patches that received some minor updates:
- seqno fence (wait condition member added)
- android (whitespace changes and a comment removed)
- add poll support to dma-buf (added comment)
