| Subject: CVE-2024-44979: drm/xe: Fix missing workqueue destroy in xe_gt_pagefault |

| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/xe: Fix missing workqueue destroy in xe_gt_pagefault |
| |

| access counter workqueues. Add those destroy calls here. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
| https://git.kernel.org/stable/c/b09ef3b762a7fc641fb2f89afd3ebdb65b8ba1b9 |
