This patch makes possible to use full 1G of memory without HIGHMEM  enabled on
PPC32 machines.

But please note it's a hack and may cause problems, I use such kernel on my
system by 2-3 week's without any problems, but you have been warnded. Look
at "Enable full 1G" option descrition for more informations.

To enable it enable: 

* Code maturity level options -> Prompt for development and/or incomplete code/drivers
* Kernel options -> Enable full 1G

WARNING: yabot expects KERNEL_START to be set to 0xc0000000 then it will refuse
         to load kernel compiled with this option enabled ! Look at
