New Revision: 261135
URL: http://svnweb.freebsd.org/changeset/base/261135

Log:
  In an effort to diagnose possible corruption of struct vm_page on some
  sparc64 machines make the page queue assert in vm_page_dequeue() more
  precise.  While I'm here switch the page lock assert to the newer style.
