  Modified files:
    sys/i386/i386        genassym.c pmap.c swtch.s 
    sys/i386/include     pmap.h 
  Log:
  Put in place the infrastructure for improved UP and SMP TLB management.
  
  In particular, replace the unused field pmap::pm_flag by pmap::pm_active,
  which is a bit mask representing which processors have the pmap activated.
  (Thus, it is a simple Boolean on UPs.)
  
  Also, eliminate an unnecessary memory reference from cpu_switch()
  in swtch.s.
