[PATCH 0/3] Rework work queue usage

[Matthew Brost <matthew.brost@intel.com>]

Avoid sleeping or grabbing locks in work queues shared with the system.
Recent changes to work queues [1] have exposed deadlocks [2] in Xe.

I believe only patch #1 is required to unblock CI in 6.9rc1 [2] but
likely all patches should be included in stable kernels.
