    ttm porting: Translate locking primitives
    
    * rw locks to lockmgr locks
    
    * sx locks to lockmgr locks
    
    * Some mtx locks to lockmgr locks
    
    * Some mtx_locks to spinlocks
    
    Some more locks could probably be converted to spinlocks but this
    can be dangerous.
    Better use lockmgr locks first and be sure the code runs without any
    issue before trying to optimize it.
