    kernel - Detect edge cases in ELF note handling
    
    * Do more stringent tests on ELF note structures and headers to
      avoid possible panics on page-crossings.
    
    * Patch constructed from examination of a similar fix made to FreeBSD
      cvs/1.227.  However, our patch is written a different way.
