+Subject: [PATCH 1412/4131] drm/amdgpu: Add PDE0 vm fault as invalid address
+ protection fault
+
+The VM generally raises two kind of invalid address protection fault:
+PDE0 (page directory entry not present) or VALID(page table entry
+not valid). Both need to be reported as invalid protection fault to user.
