Author: jhb Date: Wed Apr 11 20:19:29 2012 New Revision: 234146 URL: http://svn.freebsd.org/changeset/base/234146 Log: MFC 232228,233613: Move the DTrace return IDT vector back up from 0x20 to 0x92. The 0x20 vector is currently dedicated to servicing IRQ 0 from the 8259A's, so it shouldn't be overloaded for DTrace.
