    sys/kern             sysv_msg.c sysv_sem.c sysv_shm.c 
  Log:
  Explicitly use an unsigned index for 'which' in shmsys(), msgsys(), and
  semsys(), so the implications of the use of a negative index become obvious.
  Fix the misdocumented 'which' UAP argument, which is actually signed.
  
  Note: There is no security issue because sizeof() is unsigned but such
  non-explicit comparisons are a very dangerous way to code and this fixes
  that.
