    kernel - kernel - Incidental MPLOCK removal (usched, affinity)
    
    * Affinity code needs to be protected via p->p_token and lwp->lwp_token.
      Remove use of the mplock.
    
    * If tid is -1 getaffinity() will lookup the lowest-numbered thread,
      and setaffinity will adjust ALL threads associated with the process.
    
    * usched doesn't need mplock2.h
