10 With split page table lock we have separate per-table lock to serialize
11 access to the table. At the moment we use split lock for PTE and PMD
42 If split lock is disabled, all tables are guarded by mm->page_table_lock.
47 Hugetlb and split page table lock
50 Hugetlb can support several page sizes. We use split lock only for PMD
56 takes pmd split lock for PMD_SIZE page, mm->page_table_lock
61 Support of split page table lock by an architecture
64 There's no need in special enabling of PTE split page table lock: everything
72 PMD split lock only makes sense if you have more than two page table
