  Modified files:
    sys/alpha/alpha      machdep.c 
  Log:
  Optimize bzero() by unrolling the aligned quadword loop and moving the length
  manipulation away from the length comparison.  Measurements on beast.cdrom.com
  show >3X improvement over the original code on large block sizes, putting the
  performance on par with the optimized assembly code in libc.
