This patch set builds on Andi Kleen's patches for GB pages for hugetlb posted on March 16th. This set adds support for 16G huge pages on ppc64. Supporting multiple huge page sizes on ppc64 as defined in Andi's patches is not a part of this set; that will be included in a future patch.
The first patch here adds an arch callback since the 16G pages are not allocated from bootmem. The 16G pages have to be reserved prior to boot-time. The location of these pages are indicated in the device tree. Support for 16G pages requires a POWER5+ or later machine and a little bit of memory.
