I'm sorry, I thought we agreed at the summit to convert this to
whitelisting because it was likely better to simply not expose unknown
ACPI tables to guests.

I guess the commit message could be something like:

"The following list of whitelisted APIC tables are either known to work
or don't require any resources to be mapped in either the IO or the
memory space.

This list is expected to be expanded as more testing is performed."

Thanks, Roger.
