Subject: [REPOST PATCH 0/8] fence synchronization patches
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.
Patch 7 and 8 provide some helpers, and allow use of RCU in the
reservation api. The helpers make it easier to convert ttm, and
make dealing with rcu less painful.
Patches slightly updated to fix compilation with armada and
new atomic primitives, but otherwise identical.
