The SLUB allocator relies on struct page fields first_page and slab, overwritten by ptl when SPLIT_PTLOCK: so the SLUB allocator cannot then be used for the lowest level of pagetable pages. This was obstructing SLUB on PowerPC, which uses kmem_caches for its pagetables. So convert its pte level to use normal gfp pages (whereas pmd, pud and 64k-page pgd want partpages, so continue to use kmem_caches for pmd, pud and pgd).
