    sys/amd64/include    pmap.h 
  Log:
  Add support for automatic promotion of 4KB page mappings to 2MB page
  mappings.  Automatic promotion can be enabled by setting the tunable
  "vm.pmap.pg_ps_enabled" to a non-zero value.  By default, automatic
  promotion is disabled.  (Expect this to change.)
