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
