  - drm/xe/guc: Hold device ref until queue teardown completes GuC exec queue destruction can run
    asynchronously. If the final device put happens from a destroy worker, drmm cleanup can end up draining
    the same workqueue and deadlock. Hold a drm_device reference for the queue lifetime and drop it after
    queue teardown completes. This keeps drmm cleanup from running while async destroy work is still pending.
    Move GuC destroy work to a module-lifetime Xe workqueue and flush it on PCI remove so hot-unbind/rebind
    still waits for pending destroy work. With queue-held device refs, guc_submit_sw_fini() cannot run with
    live GuC IDs. Replace the fini wait with an assertion and remove the unused fini_wq. v2: - Rebase v3: -
    Switch to queue-lifetime drm_dev_get()/drm_dev_put() model. (Matt) - Queue async teardown on system_dfl_wq
    instead of xe->destroy_wq. (Matt) - Drop separate deferred drm_dev_put worker. - Remove stale
    drain_workqueue(xe->destroy_wq) from guc_submit_sw_fini(). v4: - Replace the guc_submit_sw_fini() wait
    with an assertion and remove the now-unused fini_wq. (sashiko) v5: - Move destroy work to a module-
    lifetime Xe workqueue instead of system_dfl_wq. (Matt) - Flush the module-lifetime destroy workqueue
    during PCI remove to preserve the old device-remove wait semantics. v6: - Keep SVM pagemap destroy work on
    the per-device destroy_wq to avoid letting it outlive the xe_device/drm_device. (Sashiko) - Use
    WQ_MEM_RECLAIM for xe->destroy_wq because SVM pagemap destroy work can be queued from the reclaim path.
    v7: - Drop the per-device xe->destroy_wq and use the module-level destroy WQ for SVM pagemap destroy as
    well. (Matt) - Rename xe_exec_queue_destroy_wq_*() helpers to xe_destroy_wq_*() helpers because the WQ is
    no longer exec-queue specific. (Matt) v8: - Rebase. v9: - Keep SVM pagemap destroy work on the per-device
    WQ_MEM_RECLAIM destroy_wq because it can be queued from reclaim and embeds the dev_pagemap used by devres
    teardown. (Sashiko) - Keep the module-level destroy WQ GuC-only and drop WQ_MEM_RECLAIM from it. - Update
    the module-WQ kdoc to document the GuC/SVM split. v10: - Keep xe->destroy_wq per-cpu while adding
    WQ_MEM_RECLAIM to fix the workqueue allocation warning. v11: - Drop the SVM pagemap destroy comment as it
    was revision-specific. (Thomas) v12: - Rebase. (cherry picked from commit
    da1124abac689cc2b1d8995e5f0a816f8a122edb) (CVE-2026-68382)
