| Subject: habanalabs/gaudi: set the correct cpu_id on MME2_QM failure |
| |
| From: Koby Elbaz <kelbaz@habana.ai> |
| |
| [ Upstream commit b92c637c5f5ef7e3e21dbc7bfa7f1999450f3902 ] |

| This fix was applied since there was an incorrect reported CPU ID to GIC |
| such that an error in MME2 QMAN aliased to be an arriving from DMA0_QM. |
