nios2 allocates kernel PTE pages with __get_free_pages(GFP_KERNEL | __GFP_ZERO, PTE_ORDER); and user page tables with pte = alloc_pages(GFP_KERNEL, PTE_ORDER); if (pte) clear_highpage(); The PTE_ORDER is hardwired to zero, which makes nios2 implementation almost identical to the generic one. Switch nios2 to the generic version that does exactly the same thing for the kernel page tables and adds __GFP_ACCOUNT for the user PTEs. The pte_free_kernel() and pte_free() versions on nios2 are identical to the generic ones and can be simply dropped.
