David Gibson d1837cba5d powerpc/mm: Cleanup initialization of hugepages on powerpc ... This patch simplifies the logic used to initialize hugepages on powerpc. The somewhat oddly named set_huge_psize() is renamed to add_huge_page_size() and now does all necessary verification of whether it's given a valid hugepage sizes (instead of just some) and instantiates the generic hstate structure (but no more). hugetlbpage_init() now steps through the available pagesizes, checks if they're valid for hugepages by calling add_huge_page_size() and initializes the kmem_caches for the hugepage pagetables. This means we can now eliminate the mmu_huge_psizes array, since we no longer need to pass the sizing information for the pagetable caches from set_huge_psize() into hugetlbpage_init() Determination of the default huge page size is also moved from the hash code into the general hugepage code.
