SPARSEMEM support for Atmel AT91SAM9G45 and M10

Hi,

     I'm resurrecting an old thread
(http://lists.arm.linux.org.uk/lurker/message/20090914.072902.97115112.en.html)
about using the two memory banks available
on Atmel AT91SAM9G45/M10. I managed to make it work on 2.6.30 by
following Russell King advice on how to configure SPARSEMEM.
     I submitted a working patch for 2.6.34 here:
http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=6143/1

The problem is that I'm unsure how to get rid of the #define that
forces high_memory value in mm/init.c, should I add a fixup function
to board-sam9m10g45ek.c to provide meminfo information ?

Regards,
Nicu Pavel.
