    sys/sys              param.h proc.h 
    sys/kern             kern_synch.c 
  Log:
  Remove PUSER entirely.  Since p_priority has nothing to do with kernel
  thread priorities, the userland scheduler can now use the entire range 0-127.
  
  Document the estcpu and other macros related to the p_priority calculation.
  
  Adjust the default values such that a cpu bound nice -20 process will not
  completely starve a nice +0 process (though it gets close!).  Note that a
  nice +2 process will not run at all in the face of a cpu bound nice -20
  process.
