My recommendation - don't do this. Why do you need to allocate this 
big chunk of consistent memory in the first place? You can do DMA 
_without_ allocating "consistent" memory. In fact, this is how 
virtually all devices work in Linux. For more info about DMA API - 
look at Documentation/DMA-API.txt.

Technically, you can make consistent pool bigger, if you really insist 
on using this approach.
