commit 95df18e42dead7a96c27c07b74b461b0e77abd84
Author: François Tigeot <ftigeot@wolfpond.org>
Date:   Sat Mar 31 20:23:56 2012 +0200

    Kernel - Restore the 64KB max. IO size limit
    
    * Some drivers and part of the kernel are dependent on an implicit
      64KB maximum IO size limit
    
    * Explicitely set it to 64KB (or MAXPHYS if it is smaller) for devices
      which do not report a default value
    
    * This should fix ATA DMA errors reported in issue #2342
