+Subject: drm/xe/mocs: Initialize MOCS index early
+
+From: Balasubramani Vivekanandan <balasubramani.vivekanandan@intel.com>
+
+commit 2a58b21adee3df10ca6f4491af965c4890d2d8e3 upstream.
+
+MOCS uc_index is used even before it is initialized in the following
+callstack
+    guc_prepare_xfer()
+    __xe_guc_upload()
+    xe_guc_min_load_for_hwconfig()
+    xe_uc_init_hwconfig()
+    xe_gt_init_hwconfig()
+
+Do MOCS index initialization earlier in the device probe.

+Subject: drm/xe: Move page fault init after topology init
+
+From: Matthew Brost <matthew.brost@intel.com>
+
+commit 3155ac89251dcb5e35a3ec2f60a74a6ed22c56fd upstream.
+
+We need the topology to determine GT page fault queue size, move page
+fault init after topology init.
