This patch adds the hugepagesz boot-time parameter for ppc64 that lets you pick the size for your huge pages. The choices available are 64K and 16M. It defaults to 16M (previously the only choice) if nothing or an invalid choice is specified. Tested 64K huge pages with the libhugetlbfs 1.2 release with its 'make func' and 'make stress' test invocations. This patch requires the patch posted by Mel Gorman that adds HUGETLB_PAGE_SIZE_VARIABLE; "[PATCH] Fix boot problem with iSeries lacking hugepage support" on 2007-11-15.

Any chance of spelling it as "hugepagesize" so that it's a little less cryptic and more difficult to typo as "hugepages"? (i.e., less confusion between them)
