Mike Rapoport fc7835c2f8 nios2: switch to generic version of pte allocation ...

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.
