This set improves per queue reset support for GC10+. This enables the legacy enforce isolation behavior to serialize access to GC for kernel queues so that only one process uses the queue at a time. When we reset the queue, only that process is effected which improves the user experience when a queue is reset. This mirrors how windows handles per queue resets. Tested on GC 10 and 11 chips with a game running and then running hang tests. The game pauses when the hang happens, then continues after the queue reset.
I tried this same approach and GC8 and 9, but it was not as reliable as soft recovery. I also compared this to Christian's reset patches, but I was not able to make them work as reliably as this series.
