commit 88647f4cbb09baaf0113c7ed0ea615e6b7cb1118
Author: Michael Opdenacker <michael.opdenacker at free-electrons.com>
Date:   Fri Mar 10 14:26:40 2017 +0100

    Mark old DocBook resources as temporarily broken
    
    - Some documentation is still in DocBook format, but no
      longer published on http://kernel.org/doc/
    
      This will be fixed in the next releases
    
    - Preferring to keep the broken links which we can
      detect and fix
