dma-buf synchronization patches

The following series implements fence and converts dma-buf and android sync to use it. Patch 6 and 7 add support for polling to dma-buf, blocking until all fences are signaled.

Maarten Lankhorst (7):
sched: allow try_to_wake_up to be used internally outside of core.c
fence: dma-buf cross-device synchronization (v16)
seqno-fence: Hardware dma-buf implementation of fencing (v4)
dma-buf: use reservation objects
android: convert sync to fence api, v3
reservation: add support for fences to enable cross-device synchronisation
dma-buf: add poll support
