  "message": "ANDROID: mm: skip pte_alloc during speculative page fault\n\nSpeculative page fault checks pmd to be valid before starting to handle\nthe page fault and pte_alloc() should do nothing if pmd stays valid.\nIf pmd gets changed during speculative page fault, we will detect the\nchange later and retry with mmap_lock. Therefore pte_alloc() can be\nsafely skipped and this prevents the racy pmd_lock() call which can\naccess pmd-\u003eptl after pmd was cleared.\n\nBug: 257443051\nChange-Id: Iec57df5530dba6e0e0bdf9f7500f910851c3d3fd\nSigned-off-by: Suren Baghdasaryan \u003csurenb@google.com\u003e\n",
