mm: memcontrol: account pagetables per node
...
For many workloads, pagetable consumption is significant and it makes
sense to expose it in the memory.stat for the memory cgroups. However at
the moment, the pagetables are accounted per-zone. Converting them to
per-node and using the right interface will correctly account for the
memory cgroups as well.

asm-generic: pgalloc: provide generic pgd_free()
...
Most architectures define pgd_free() as a wrapper for free_page().
Provide a generic version in asm-generic/pgalloc.h and enable its use for
most architectures.

nds32: use pgtable-nopmd instead of 4level-fixup
...
nds32 has only two-level page tables and can use pgtable-nopmd and
folding of the upper layers.
Replace usage of include/asm-generic/4level-fixup.h and explicit
definition of __PAGETABLE_PMD_FOLDED in nds32 with
include/asm-generic/pgtable-nopmd.h and adjust page table manipulation
macros and functions accordingly.
