There is no\ndma map of src pages and migration. j is 0 and svm_migrate_copy_memory_gart()\nwill return an uninitialized r. That can trigger out_free_vram_pages to drop\nall VRAM just set up.\n\nInitialize r and only call the last svm_migrate_copy_memory_gart if j > 0.\n\nCurrent code postponed the last page to the final copy. This patch flushes on\nthe last page when reach to the end of current drm_buddy_block; avoids another\nsvm_migrate_copy_memory_gart.",
