details:   https://anonhg.NetBSD.org/src/rev/e0f360cc8465
branches:  trunk
changeset: 993826:e0f360cc8465

description:
- Decode DMAR's ANDD (ACPI Name Space).
- Add X2APIC_MODE flag of DMAR. Note that Intel's VT-d's document says the
  flag's name is DMA_CTRL_PLATFORM_OPT_IN but actbl1.h says it's
  DMAR_X2APIC_MODE.
