Hi Dave and Sima,

Please pull the drm-xe-fixes for this week targeting v6.9-rc3.

This is a little late in the week as I was waiting a critical fix to be
applied to get our CI back. This is mainly due to some stress tests
creating hundreds of exec queues and that not playing nice with the
workqueue changes introduced in v6.9. That shouldn't be the normal use
case but was causing CI to abort further tests.  Other changes include
fixes around rebinding and TLB invalidation.

thanks
Lucas De Marchi

drm-xe-fixes-2024-04-04:
- Stop using system_unbound_wq for preempt fences,
   as this can cause starvation when reaching more
   than max_active defined by workqueue
- Fix saving unordered rebinding fences by attaching
   them as kernel feces to the vm's resv
- Fix TLB invalidation fences completing out of order
- Move rebind TLB invalidation to the ring ops to reduce
   the latency
