6 multi-threaded applications due high contention on the lock. To improve
7 scalability, split page table lock was introduced.
9 With split page table lock we have separate per-table lock to serialize
10 access to the table. At the moment we use split lock for PTE and PMD
13 There are helpers to lock/unlock a table and other accessor functions:
15 maps pte and takes PTE table lock, returns pointer to the taken
16 lock;
20 allocates PTE table if needed and take the lock, returns pointer
21 to taken lock or NULL if allocation failed;
