After having re-read the ACPI spec a few days ago, I agree that more
ACPI stuff is gonna wind up in the kernel. We don't want to have to
bounce back to userspace just to parse tables which tell us key things
like APIC or CPU info.

(fwiw here is a kernel traffic reference for ACPI: )

Parsing tables is way different from parsing AML. Why does there need
to be an AML parser in the kernel? It seems like Andy adequate
responded to your list of drawbacks at the above link, so I hope you
mind my request for a clarification of the issue.
