[PATCH 00/10] Reset improvements for GC10+

[Alex Deucher]

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.
