Merge revision 183061 from head to stable/7.

> Allow multiple locks to be acquired by detecting corresponding
> bit flag, otherwise if a thread acquired a lock, another thread
> or the current thread itself can no longer acquire another lock
> because thread_mask_set() return whole flag word, this results
> bit leaking in the word and misbehavior in later locking and
> unlocking.
