6.7-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 3380fcad2c906872110d31ddf7aa1fdea57f9df6 ]
This needs to be set to 1 to avoid a potential deadlock in the GC 10.x and newer. On GC 9.x and older, this needs to be set to 0. This can lead to hangs in some mixed graphics and compute workloads. Updated firmware is also required for AQL.
