Vulnerability Title
drm/xe: Process deferred GGTT node removals on device unwind
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Process deferred GGTT node removals on device unwind
While we are indirectly draining our dedicated workqueue ggtt->wq
that we use to complete asynchronous removal of some GGTT nodes,
this happends as part of the managed-drm unwinding (ggtt_fini_early),
which could be later then manage-device unwinding, where we could
already unmap our MMIO/GMS mapping (mmio_fini).
This was recently observed during unsuccessful VF initialization:
[ ] xe 0000:00:02.1: probe with driver xe failed with error -62
[ ] xe 0000:00:02.1: DEVRES REL ffff88811e747340 __xe_bo_unpin_map_no_vm (16 bytes)

[ ] xe 0000:00:02.1: [drm:drm_managed_release] REL ffff88810ef80140 ggtt_fini_early (8 bytes)
and this was leading to:
[ ] BUG: unable to handle page fault for address: ffffc900058162a0
[ ] #PF: supervisor write access in kernel mode
[ ] #PF: error_code(0x0002) - not-present page
[ ] Oops: Oops: 0002 [#1] SMP NOPTI

[ ] Call Trace:

Add managed-device action that will explicitly drain the workqueue
with all pending node removals prior to releasing MMIO/GSM mapping.
