From ad195fdafd71f96c2b924fdec4d81c359a0ebe2b Mon Sep 17 00:00:00 2001 From: jhb Date: Wed, 8 Jan 2003 20:46:25 +0000 Subject: [PATCH] Add code to parse the contents of an ACPI MADT table and to dump its contents in the form of a comment in the acpidump output. The output is not in the prettiest output, but it does work correctly.
