Subject: [PATCHv3 00/17] Add missing __PAGETABLE_{PUD,PMD}_FOLDED defines and introduce CONFIG_PGTABLE_LEVELS

This is rearrangment of CONFIG_PGTABLE_LEVELS patchset.

The first patch adds all missing __PAGETABLE_{PUD,PMD}_FOLDED defines.
This will fix mm->nr_pmds underflow on affected architectures and should
go into v4.0.

The rest is just a rebase of CONFIG_PGTABLE_LEVELS patchset and can wait
until 4.1.

Kirill A. Shutemov (17):
  mm: add missing __PAGETABLE_{PUD,PMD}_FOLDED defines
  alpha: expose number of page table levels on Kconfig level
  arm64: expose number of page table levels on Kconfig level
  arm: expose number of page table levels on Kconfig level
  ia64: expose number of page table levels on Kconfig level
  m68k: mark PMD folded and expose number of page table levels
  mips: expose number of page table levels on Kconfig level
  parisc: expose number of page table levels on Kconfig level
  powerpc: expose number of page table levels on Kconfig level
  s390: expose number of page table levels
  sh: expose number of page table levels
  sparc: expose number of page table levels
  tile: expose number of page table levels
  um: expose number of page table levels
  x86: expose number of page table levels on Kconfig level
  mm: define default PGTABLE_LEVELS to two
  mm: do not add nr_pmds into mm_struct if PMD is folded
