svn commit: r219630 - projects/altix/sys/conf

[Marcel Moolenaar]

Author: marcel
Date: Mon Mar 14 05:16:12 2011
New Revision: 219630
URL: http://svn.freebsd.org/changeset/base/219630

Log:
  Move the actual code to the front of the segment and make sure the IVT
  can be put right at the front when put in its own section. This makes
  sure that when the loader can only map a relatively small part of the
  PBVM, the IVT and the startup code is wired.
