You are right. I didn't think that through when I replied. We do lose
some of it for MMIO (not IO). So we cannot really go all the way to 4G

should the commit header really be >= 4G. I don't think
This patch enables 32bit PPC's (with 36bit physical address space, e.g.
IBM/AMCC PPC44x) to run with more than 2GB of RAM. Mostly its just
replacing types (unsigned long -> phys_addr_t).
Tested on an AMCC Katmai with 4GB of DDR2.
