Kirill A. Shutemov c07af4f1ce mm: add missing __PAGETABLE_{PUD,PMD}_FOLDED defines ... Core mm expects __PAGETABLE_{PUD,PMD}_FOLDED to be defined if these page table levels folded. Usually, these defines are provided by <asm-generic/pgtable-nopmd.h> and <asm-generic/pgtable-nopud.h>. But some architectures fold page table levels in a custom way. They need to define these macros themself. This patch adds missing defines. The patch fixes mm->nr_pmds underflow and eliminates dead __pmd_alloc() and __pud_alloc() on architectures without these page table levels. Signed-off-by: Kirill A.
