    sys/i386/i386        locore.s pmap.c 
  Log:
  In order to satisfy ACPI's need for an identity mapping, modify the
  temporary mapping created by locore so that the lowest two to four
  megabytes can become a permanent identity mapping.  This implementation
  avoids any use of a large page mapping.
