For NSys, we're interested in having detailed information on what task waits on a particular prefence or requests a particular postfence. This is implemented by adding two extra fields, 'task_syncpt_id' and 'task_syncpt_thresh' to 'struct nvhost_task_fence', to record the task this particular fence is associated with. To avoid race conditon in pva_submit (similar to what was fixed in 0c2065fd669926536f79fd9e8ec33f33cbdcae2e), PVA task memory management is changed to use simple kref-based scheme, much like it's done in DLA. Finally, this patch renames syncpoint fields of 'task_fence' to 'syncpt_id' and 'syncpt_thresh' to match the same field names in other events, which is intended to simplify Python scripting.
