Subject: [PATCH 0/5] Hugetlb for 32-bit FSL PowerPC BookE

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.

Cheers,
Becky
