    sys/ia64/ia64        mp_machdep.c pmap.c 
    sys/ia64/include     pmap.h 
  o  s/vhpt_size/pmap_vhpt_log2size/g
  o  s/vhpt_base/pmap_vhpt_base/g
  o  s/vhpt_bucket/pmap_vhpt_bucket/g
  o  Declare the above in <machine/pmap.h>
  o  Move the vm.stats.vhpt.* sysctls to machdep.vhpt.*
  o  Create a tunable machdep.vhpt.log2size, with corresponding sysctl.
     The tunable allows the user to specify the VHPT size from the loader.
  o  Don't keep track of the number of PTEs in the VHPT. Calculate the
     population when necessary by iterating the buckets and summing up
     the length of the buckets.
  o  Don't perform the tpa instruction with a bucket lock held. The
     instruction can (theoretically) fault and locking is not needed.
