On a Dell R6515, acpimadt(4) prints this 512 times during boot:
acpimadt0: unknown apic structure type 80
Previous generations of machines had a few of these, and they were easy
enough to ignore, but 512 is a bit excessive.
On further inspection, it seems types 0x80 through 0xFF are reserved for
OEM specific uses, which we're never going to be able to work with, so
complaining about it seems pointless. If we encounter a non-OEM type we
don't know about, we should still report that though.
ok?
