I can look more into this tomorrow. When I was testing linux-next
last week, the fixups weren't working with device tree anyway, so I
might need to come up with another solution.

The fixups are called with the ATAGS, which aren't available with DT.
The meminfo is passed to the fixup, but it hasn't been initialized
from the old ATAG information, so there isn't anything to fix up.

I think I'm just going to have to convince our bootloader people to
actually pass in the right memory information in the first place.
