- Use the headers from ACPI-CA to define various constants and structures
for table layouts, etc. rather than homerolling our own structures and constants in acpidump.h. - Verify the extended checksum on the RSDP. - Handle new ACPI 3.0 fields in MADT including X2APIC entries and UIDs for local SAPICs. - Add handling for new ACPI 3.0 flags in the FADT.
