1) Some sysctl vars are declared __read_mostly
2) We can avoid updating stack[] when doing an AVL lookup only.
lookup() macro is extended to receive a second parameter, that may be NULL
in case of a pure lookup (no need to save the AVL path). This removes
unnecessary instructions, because compiler knows if this _stack parameter is
NULL or not.
