That should work, but I don't think it is the proper fix. The underlying
issue here is that ZONE_DMA/DMA32 sizing is something that needs to
be propagated to memblock and dma-direct as is based around addressing
limitations. But our zone initialization is such a mess that we
can't just reuse a variable. Nicolas has started to clean some of
this up, but we need to clean that whole zone initialization mess up
a lot more.
