Implement HugeTLB for 32-bit BookE PowerPC. There is also some infrastructure in place for 64-bit BookE as well from David Gibson; I'm not sure if we want to include this at this time or not. I have only been able to build test the 64-bit configurations. Ben, let me know how you want to proceed here.
The bulk of this patch series is powerpc-specific, but there are a couple of minor fixes to the generic fs and mm code included, hence the cross-post. Note that to use this fully some modifications to libhugetlbfs are required; I expect to publish those shortly. Diffstat below.
