[PATCH V2 00/10] Reset improvements for GC10+

[Alex Deucher]

This set improves per queue reset support for GC10+.
This uses vmid resets for GFX.  GFX resets all state
associated with a vmid and then continues where it
left off.  Since once the IB uses the vmid, only
the IB is reset and execution continues after the IB.
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.
