Author: marcel Date: Sat Jul 3 20:19:20 2010 New Revision: 209671 URL: http://svn.freebsd.org/changeset/base/209671 Log: Allocate and setup an interrupt vector for corrected machine checks. For now, just print when we get the interrupt, but eventually we need to collect the details and provide a more useful report.
