Author: neel Date: Fri Dec 21 01:31:56 2012 New Revision: 244526 URL: http://svnweb.freebsd.org/changeset/base/244526 Log: The MPtable specification allows for an 8-bit "BUS ID" and "I/O APIC ID". Since the 'busses[]' and 'apics[]' arrays are indexed by these 8-bit IDs make sure that they have enough space to accomodate up to 256 entries.
