  Log:
  Don't allow MAXMEM or hw.physmem to extend the top of memory if our memory
  map was obtained from the SMAP.  SMAP is trustworthy, and the memory
  extending feature is a band-aid for older systems where FreeBSD's methods
  of detecting memory were not always trustworthy.  This fixes the issue
  where using hw.physmem could result in the ACPI tables getting trashed
  breaking ACPI.
