    sys/i386/acpica      madt.c 
  Log:
  - Change madt_map_table() to verify the checksum of any table it is asked
    to map.  If the checksum fails, the table is unmapped and a NULL pointer
    returned.
  - For ACPI version >= 2.0, check the extended checksum of the RSDP.
    AcpiOsGetRootPointer() already checks the version 1.0 checksum.
  - Remap the full MADT table at the end of madt_probe() so that we verify
    its checksum before saying it is really there.
